[Prior Art] In recent years, various portable electronic devices such as notebook computers and mobile phones have been used for a long time without charging, and people are trying to use fuel cells for power supplies of such portable electronic devices. The fuel cell can generate electricity by supplying fuel and air. As long as the fuel is replenished, it can generate electricity for a long time. Therefore, as long as the fuel cell can be reduced, it becomes a very advantageous system for powering the portable electronic device. In particular, a direct methanol fuel cell (DMFC) using a methanol fuel having a high energy density can be miniaturized and the fuel is easily handled, so that it is considered to be a power source of the portable device φ. The known liquid fuel supply method of the DMFC includes an active mode such as a gas supply type and a liquid supply type, or an internal vaporization type in which a liquid fuel in a fuel tank is vaporized inside the battery to be supplied to the fuel electrode. Wait for the Passive method. Among them, the passive mode is conducive to the miniaturization of the DMFC. In the internal vaporization type passive DMFC, the liquid fuel in the fuel storage portion is vaporized by a fuel impregnation layer or a fuel vaporization layer, and is supplied to the fuel electrode (see, for example, Patent Documents 1 to 2). For the supply of the methanol fuel in the fuel accommodating portion, for example, a fuel tank of a satellite type (external injection type) is used. - 201025714 When a methanol fuel is supplied by a fuel cartridge, a socket for a fuel cell and a fuel cell are generally used. A fuel cell coupler composed of a piug. Each of the fuel cell socket and the fuel cell plug has a valve mechanism having a built-in valve body (valve body), and the valve body of the fuel cell is connected to the fuel cell socket to connect the valve body of the fuel cell to the valve body. The institution has become open. In this case, for example, when the fuel cell is equipped with a fuel cell socket, a fuel cell plug is attached to the fuel cartridge, and the fuel cell plug is inserted into the fuel cell socket, so that the liquid fuel contained in the fuel cartridge can be supplied to the fuel cell. The fuel cell, specifically the fuel containment unit. Further, the fuel cell plug is pulled out from the fuel cell socket, and the valve body separation setting valve mechanism is closed, whereby the supply of the liquid fuel can be shut off. With regard to such a fuel cell coupler, for example, the concentration (purity) of the liquid fuel necessary for the specification of the fuel cell is not constant, and therefore, an identification means is provided so that only a specific concentration of fuel conforming to the specifications of the fuel cell can be supplied. 'Cannot supply other concentrations incorrectly. Specifically, one of the key grooves or the keys is provided on the inner diameter side of the fuel cell socket, and the other side is provided on the outer diameter side of the fuel cell plug, thereby performing the fuel cell socket and the fuel cell plug. Identification between (for example, Patent Document 3).

A reduced diameter portion 2 2c whose diameter is reduced from the front end side toward the rear end side is formed between the nozzle fitting portion 22a and the main body fitting portion 22b on the front end side of the fitting member 22. In this manner, the identification member 24 is pushed and pressed by the distal end side, and the fitting member 22 can be moved toward the outer diameter side. Further, on the rear end side of the fitting member 22, for example, at the same position as the rear end surface of the nozzle fitting portion 22a, a flat portion 22d is formed, and for the flat portion 22d, the elastic portion for the guiding portion 19 is formed by the rear end side. By pushing and pressing, the entire nozzle guide portion 14 including the fitting member 22 can be pressed toward the distal end side. Further, a groove portion 22e' extending in the circumferential direction is formed on the outer diameter side of the main body fitting portion 22b.

In addition, Fig. 4(a) shows an external view in which the upper side is the front end side, and Fig. 4(b) shows an external view in which the upper side is the rear end side. Also shown in Fig. 4 is the fitting portion pressing member 23. The fitting member 22 of Fig. 4 is formed by forming the main body fitting portion 22b, the reduced diameter portion 22c, the flat portion 22d, and the groove portion 22e in a substantially annular shape. With respect to the fitting member 22, the opening portion 22f' is formed in a part of the circumferential direction by the easy expansion of the diameter, and the appearance is c-shaped. Further, the nozzle fitting portions 22a to 201025714 are formed, for example, at equal intervals in the circumferential direction. In either case, the fitting member 2 is pressed by the fitting portion pressing member 23 from the outer diameter side, so that the nozzle fitting portion 22a of the fitting member 22 is fitted into the guide portion of the nozzle 1 lb. In addition, since the recessed portion 1 is expanded in diameter toward the outer diameter side of the fitting member 22, the nozzle fitting portion 22a of the fitting member 22 can be removed by the guide portion recess 1 If of the nozzle Ub. After the diameter is expanded and the diameter is reduced again, the guide portion recessed portion Ilf of the nozzle lib is again fitted into the nozzle fitting portion 22a of the fitting member 22. Further, when only the fitting member 22 can be appropriately expanded in diameter and reduced in diameter, it is not necessary to provide the fitting portion pressing member 23. The identification member 24 and the identification convex portion 41b of the identification means of the socket 2 are disposed so as to be the identification means, and the reduced diameter portion of the fitting member 22 is pressed by the pressing of the identification convex portion 41b of the socket 2. 22c, in this way, the fixing of the nozzle lib to the cylindrical body 21 by the fitting member 22 is released, and the nozzle lib can be protruded from the cylindrical body 21. The identification member 24 is disposed on the front end side of the fitting member 22, particularly the reduced diameter portion 22c. Further, the arrangement of the reduced diameter portion 22c of the fitting member 22, the identification member 24', and the identification convex portion 4 1 b of the identification means of the socket 2 is arranged correspondingly. With this configuration, the function of the identification means can be utilized, and the fixing of the nozzle lib by the fitting member 22 to the cylindrical body 21 can be effectively released. The identification member 24 has, for example, a plate-like portion 24a, and a convex portion 24b formed at a substantially central portion on the outer diameter side of the plate-like portion 24a. The plate-like portion 24a is movably disposed between the nozzle Ub and the cylindrical body 21 for transmitting the pressing of the identification convex portion 41b of the socket -16 to 201025714 to the reduced diameter portion 22c of the fitting member 22. Further, the convex portion 24b is movably fitted and disposed in the groove portion 21b of the cylindrical body 21, whereby the movement of the identification member 24 in the circumferential direction is suppressed, and the axial direction can be appropriately moved. FIG. 5 shows an example of the identification member 24. Fig. 5(a) shows an external view of the state viewed from the outer diameter side, Fig. 5(b) shows a plan view of the state viewed from the distal end side, and Fig. 5(c) shows a state of the state viewed from the outer diameter side. Floor plan. The plate-like portion 24a is formed in a substantially rectangular shape, for example, and is curved in a convex shape on the outer diameter side in accordance with the inner surface shape of the cylindrical body 21. Further, the convex portion 24b is formed, for example, in a substantially hemispherical shape, and is formed integrally with the substantially central portion on the outer diameter side of the plate-like portion 24a. Such a substantially rectangular shaped member 24 is generally arranged such that the longitudinal direction coincides with the axial direction of the plug 1. Such a plug 1 is generally other than a non-metallic material such as polypropylene (PP) or polyphenylene sulfide (PPS) except for the ankle rings 16, 17 , the valve elastic body 18, and the φ portion elastic body 1 9 . In addition to high-density polyethylene (HDPE), polystyrene (PS), etc., it is also possible to use super-plastic plastics such as polyetheretherketone (PEEK) and liquid crystal polymer (LCP) which are resistant to methanol. Or PET (polyethylene terephthalate), PBT (polybutylene terephthalate), polyoxymethylene (POM) and other general engineering plastics. Further, the socket 2 is also referred to as a female side coupler, and has a socket body 41; and a valve body 42 disposed inside the shaft direction. -17- 201025714 The socket body 4 1 has, for example, a slightly cylindrical front end side cylindrical portion 43 disposed on the front end side, and an intermediate cylindrical portion 44 which is fitted and fixed by the rear end side cylindrical portion 43 and the rear end side thereof; And a rear end side tubular portion 45 that is fitted and fixed by the rear end side of the intermediate tubular portion 44. The front end side of the socket main body 41 serves as a nozzle insertion opening 41a for inserting the nozzle lib of the plug 1. Further, on the front end side of the socket main body 41, for example, the identification convex portion 41b protruding from the front end side is formed at two positions in the circumferential direction as the identification means of the socket 2. As described above, the identification convex portion 41b is disposed in the circumferential direction in alignment with the identification member 24 of the plug 1, and the fixing member 24 of the plug 1 is pressed to release the fixing of the nozzle lib to the cylindrical body 21. The nozzle lib can be protruded from the cylindrical body 21. Further, the identification convex portion 41b is formed integrally with the socket main body 41, specifically, a portion of the distal end side tubular portion 43 extending from the distal end side. Further, the identification convex portion 4 1 b is formed, for example, by projecting an end surface of the fuel receiving portion 9 to which the socket 2 is attached. The intermediate tubular portion 44 and the rear end side tubular portion 45 together form a valve chamber, and a guide hole 44a for inserting the valve body 42 is formed on the distal end side. Further, the rear end side tubular portion 45 is formed with a valve apex portion 45a in the axial center portion for defining the movement of the valve body 42 toward the rear end side, and a majority of the flow path of the liquid fuel is formed at equal intervals on the outer circumference thereof. Hole 45b. The valve body 42 has a valve head portion 42b, and has a small diameter 'the front end side spool portion 42a and the rear end side spool portion 42c formed at both ends of the valve portion head 42b. . The front end side spool portion 4 2 a ' is movably inserted into the guide hole 4 4 a, and the extension 201025714 extends to the inside of the front end side tubular portion 43. A groove portion that serves as a flow path of the liquid fuel in the axial direction (not shown) is formed on the side surface portion of the distal end side spool portion 42a. In this way, the liquid fuel can be effectively passed through the pilot hole 44a. Further, the valve head portion 42b and the rear end side spool portion 42c are movably disposed inside the intermediate tubular portion 44. In the inside of the rear end side tubular portion 45, a 〇 ring 46 is disposed on the front end side of the valve head portion 42b, and a valve φ elastic body 47 such as a compression spring is disposed on the rear end side for the valve body 42. Press to the front side. The valve elastic body 47 is disposed, for example, on the rear end side of the valve head portion 42b so as to surround the outer periphery of the rear end side spool portion 42c and the valve top portion 45a. In the separated state, the valve body 42 (the valve head portion 42b) is pressed to the front end side by the valve elastic body 47. Thus, the guide hole 44a is blocked by the ring 46 and the valve head portion 42b, and the valve mechanism is set to In the closed state, the outflow (countercurrent) of the liquid fuel of the outlet 2 is suppressed. Due to this point of view, the outer diameter of the annulus 46 or the valve head 42b is set to be larger than the inner diameter of the guide hole 44a. φ Further, in the connected state, the valve body 42 is moved toward the rear end side, the guide hole 44a is opened, and the valve mechanism is opened. In this way, the liquid fuel ejected from the plug 1 can pass through the guide hole 44a through the rear end side. In the inside of the distal end side tubular portion 43, an elastic body retainer 48 having a bellows shape constituted by a rubber retainer or the like is disposed so as to cover the outer periphery of the distal end side spool portion 42a. The elastomer holder 48' is formed such that the front end side thereof is fitted to the seal recess portion lid of the nozzle 11b, and the inside of the seal holder iib is sealed. The elastic body retainer 48 can be stretched in the axial direction according to the shape of the bellows and the material property (rubber elasticity), and -19-201025714 can be contracted by the insertion of the nozzle lib, and the sealing state can be maintained even when the nozzle lib is inserted. A holder supporting member 49 is disposed on the outer peripheral side of the front end side of the elastic body holder 48, and the front end side of the elastic body holder 48 is supported by the holder supporting member 49. Further, while the holder portion 49 is formed on the inner diameter side of the distal end side tubular portion 43, the movement of the holder supporting member 49 toward the distal end side is restricted, and the elastic holder is placed on the rear end side of the holder supporting member 49. 48 is disposed in a slightly contracted state in the axial direction. Thus, the rear end side of the elastic body retainer 48Q is brought into contact with the periphery of the pilot hole 44a of the intermediate tubular portion 44 to be in a sealed state. The support member elastic body 51 such as a compression spring is disposed on the rear end side of the holder supporting member 49 to move the holder supporting member 49 to the rear end side and then return to the original position. The material of the socket 2 is generally other than a non-metallic material such as polypropylene (PP) or polyphenyl except for the annulus 46, the valve elastic body 47, the elastomer holder 48, and the support member elastic body 51. It is composed of sulphide (PPS), high-density polyethylene (HDPE), polystyrene (PS), etc., and may also be made of polyetheretherketone (PEEK) or liquid crystal polymer (LCP) having methanol resistance. Such as super engineering plastics, or PET (polyethylene terephthalate), PBT (polybutylene terephthalate), polyoxymethylene (POM) and other general engineering plastics. The connection of the plug 1 to the socket 2 will be described below. First, when the plug is connected to the socket 2 by the state shown in FIG. 2, the identification means of the socket 2, that is, the identification convex portion 4丨b, is inserted into the nozzle guide portion 14 of the plug 1 as shown in FIG. Strictly speaking, it should be the inner diameter side of the cylindrical body 21 -20-201025714, which is connected to the identification member 24. Further, when the plug 1 is pressed toward the socket 2, the identification member 24 is moved toward the rear end side because the identification convex portion 4 1 b of the socket 2 is pressed in the reverse direction. At this time, the identification member 24 pushes the compression-diameter portion 22c from the distal end side to move the fitting member 22 toward the outer diameter side. In particular, with respect to the outer diameter side of the fitting member 22, the guide portion recessed portion 1 If of the nozzle 1 lb is removed by the nozzle fitting portion 22a of the fitting member 22, and the nozzle 1 lb is released. The fixing of the body 21 φ allows the nozzle lib to protrude from the cylindrical body 21. As described above, when the push plug 1 that can be pushed is pressed against the socket 2 again, as shown in FIG. 7, the nozzle lib can be protruded from the tubular body 21 and inserted into the inside of the socket 2, so that the valve body 12 of both, 42 is connected. At this time, the elastomer retainer 48 of the socket 24 is fitted into the seal recess 11d of the nozzle lib, and the seal recess 11d and the elastomer retainer 48 are sealed, and the outflow of the liquid fuel is suppressed. Further, when the plug 1 is pushed toward the socket 2, as shown in Fig. 8, the valve body 42 of the socket 2 among the valve bodies 12, 42 of the top φ is moved toward the rear end side, and the valve mechanism of the socket 2 is opened. status. Among them, the reason why the valve mechanism of the socket 2 is first opened is that it is effective to make the valve mechanism of the liquid fuel supply side open to the open state in order to ensure safety. Here, in order to make the valve mechanism of the socket 2 open first, the pressing valve body 12 in the plug 1 is caused by the rebounding force of the valve elastic body 47 caused by the pressing valve body 42 in the socket 2. The spring force of the valve elastic body 18 is set to be large, so that the valve mechanism of the socket 2 is first opened. -21 - 201025714 Further, when the plug 1 is pushed toward the socket 2, as shown in Fig. 9, the valve body 12 is pushed backward by the valve body 42 which is abutted against the valve top portion 45a. When the side moves, the valve mechanism of the plug 1 becomes open. In this manner, while the liquid fuel is ejected from the nozzle Ub of the plug 1, the liquid fuel is finally supplied to the fuel receiving portion 9 through the elastomer holder 48 of the socket 2. Further, when the plug 1 is removed from the socket 2, when the plug 1 is pulled out from the socket 2, as shown in Fig. 8, first, the valve body 12 of the plug 1 is moved toward the distal end side, and the valve mechanism of the plug 1 is closed. Thereafter, when the plug 1 is pulled out by the socket 2, as shown in Fig. 7, the valve body 42 of the socket 2 is moved toward the front end side, and the valve mechanism of the socket 2 is closed. Further, when the plug 1 is pulled out by the socket 2, the nozzle 1 1 b moves toward the rear end side with respect to the nozzle guide portion 14, and as shown in Fig. 6, the guide portion recess portion Ilf of the nozzle 1 1 b is fitted. At the position of the nozzle fitting portion 22a of the member 22, the nozzle fitting portion 22a of the fitting member 22 is fitted into the guiding portion recess Uf of the nozzle 1 lb. In this way, the cylindrical body 21 can be fixed to the nozzle lib again, so that the nozzle lib does not protrude from the cylindrical body 21. According to the plug 1 and the socket 2, only the identification means of the socket 2, that is, the size and arrangement of the identification convex portion 41b, coincide with the identification means of the plug 1, that is, the size and configuration of the identification member 24, or the socket 2 In the case where the outer diameter of the inner diameter level coincides with the gap between the nozzle 1 lb of the plug 1 and the nozzle guide portion 14, the nozzle 1 1 b can protrude from the nozzle guide portion 14 and the plug 1 can be connected to Socket 2. In addition, the identification means of the socket 2 does not coincide with the identification means of the plug 1-22-201025714, or the outer diameter of the inner diameter of the socket 2, and the gap between the nozzle lib of the plug 1 and the nozzle guide 14 are inconsistent. The nozzle 1 1 b cannot protrude from the nozzle guide portion 14, and the plug 1 cannot be connected to the socket 2. Further, when it is to be connected to a socket which is excessively large for the nozzle lib, for example, the nozzle guide portion 14 provided on the outer diameter side of the nozzle '11b, specifically, the cylindrical body 21, is attached to the insertion port of the socket 2. At the edge portion, the nozzle Ub cannot be inserted into the inside of the socket 2, the valve mechanism is kept in the closed state, and the outflow of the liquid fuel is ❿ίΦ Μ ° The other plug 1 of the present invention will be described below. Fig. 10 is a cross-sectional view showing the state in which the plug 1 of the present invention and the coupler 3 of the socket 2 suitable for the plug 1 are separated. Figure 11 shows the nozzle guide 31 of the plug 1. Fig. 11 (a) is an external view of the state observed from the front end side, Fig. 1 1 (b) is a plan view of the state viewed from the front end side, and Fig. 1 1 (c) shows the nozzle shown in Fig. 11 (b) The right side view of the state in which the lead portion 3 1 is viewed from the right side, and FIG. 1 1 (d) is the lower side view of the state in which the φ nozzle guide portion 3 1 shown in FIG. 1 1 (b) is viewed from the lower side, FIG. (e) is a cross-sectional view taken along line AA of the nozzle guide portion 31 shown in Fig. 11 (b). The plug 1 has a configuration of the nozzle guide portion 31 and its supporting structure ', which is different from the configuration of the nozzle guide portion 14 of Fig. 2 and its supporting structure. Specifically, the nozzle guide portion 31 has a structure in which the cylindrical body 21, the fitting member 22, and the identification member 24 of the nozzle guide portion 14 of Fig. 2 are substantially integrated. Further, the other parts of the plug 1 and the socket 2 are the same as those of the plug of Fig. 2 and the socket 2, so the difference will be described below. -23-201025714 The nozzle guide portion 3 1 ' has, for example, a main body portion 31a having a substantially annular shape as shown in Fig. 11; and a nozzle fitting portion 31b formed to protrude from the inner diameter side of the main body portion 31a. And a reduced diameter portion 3 1 c having a reduced diameter from the front end side to the rear end side is formed on the outer diameter side of the nozzle fitting portion 31b and on the front end side of the main body portion 31a. The body portion 3 1 a is formed, for example, in a portion of the circumferential direction to form a notch portion -

31d，外觀被設爲C字狀。藉由設爲具有缺口部31d的C 字狀者，可以成爲彈性變形之擴徑容易者。本體部3 1 a ’ Q 例如係具有：頂接於導引部用彈性體1 9 ’朝前端側推壓用 的平面部3 1 e ;及由平面部3 1 e外徑側朝前端側延伸被形 成，接觸於支撐筒部11c之內面而抑制噴嘴導引部31之 傾斜用的外壁部3 1 f。 噴嘴嵌合部31b’係以突出於本體部31a內徑側的方 式，例如於圓周方向以等間隔配置2個。在各噴嘴嵌合部 3 1 b外徑側，於本體部3 1 a嚴格說爲平面部3 1 e之前端側 ，形成由前端側至後端側呈縮徑的縮徑部3 1 c。另外，關 G 於噴嘴嵌合部31b'縮徑部31c，係和圖3、4所示嵌合構 件22之噴嘴嵌合部22a、縮徑部22c具有同樣功能者，因 此省略說明。 _ 另外，於縮徑部3 1 c之前端側朝外徑側延伸而形成水 平部。藉由水平方向之設置，即使例如插座之插入口遠大 於噴嘴lib而有可能錯誤插入之情況下，可使該水平部卡 住該插座之插入口之緣部，可抑制兩者之閥本體之頂接， 可抑制閥機構之成爲開放狀態，可抑制液體燃料對外部之 -24 - 201025714 流出，可構成爲具有安全性、信賴性佳者。 於本體部31a外徑側，例如以和噴嘴嵌合部3lb之圓 周方向之配置一致而形成支撐筒部嵌合部31g。支撐筒部 嵌合部31g，係可移動地被嵌入形成於支撐筒部Uc之朝 • 軸方向延伸的導引部用溝部llg，如此而可界定噴嘴導引 . 部31之軸方向之一頓飯爲之同時，可抑制圓周方向之旋 轉。 φ 具有噴嘴導引部31之栓塞1，其之噴嘴嵌合部31b、 縮徑部3 1 c，係分別和圖3、4所示嵌合構件22之噴嘴嵌 合部22a '縮徑部22c相當，平面部31e，係和圖3、4所 示嵌合構件22之平面部22d相當，支撐筒部嵌合部31g, 係和圖3、4所示嵌合構件22之本體嵌合部22b相當（又 ，此情況下，支撐筒部1 1 c之導引部用溝部1 1 g，係和圖 2所示筒狀本體21之凹部21a相當）。 具有此種噴嘴導引部31之栓塞1與插座2可以如下 φ 被連接。 首先，由如圖10所示狀態欲將栓塞1連接於插座2 時，如圖12所示，使插座2之辨識手段、亦即辨識凸部 • 4 1 b，頂接於形成在栓塞1之噴嘴導引部31內徑側的縮徑 部31c。此時’噴嘴lib之密封凹部lid被嵌入插座2之 彈性體保持器48，而使噴嘴1 lb與彈性體保持器48之間 成爲密封狀態，而抑制液體燃料之流出。 更進一步將栓塞1朝插座2推壓時，如圖13所示， 由於被插座2之辨識凸部41b反向推壓而使縮徑部31c由 -25- 201025714 前端側被推壓，本體部3 1 a呈現擴徑。如此則’被嵌入噴 嘴lib之導引部用凹部Ilf的噴嘴導引部31被拆下，結 果噴嘴lib對噴嘴導引部31之固定被解除，成爲噴嘴lib 可由噴嘴導引部31突出之狀態。另外，如此而更進一步 插入噴嘴lib時，頂接之閥本體12、42之中插座2之閥 · 本體42朝後端側移動，插座2之閥機構成爲開放狀態。 - 更進一步將栓塞1朝插座2推壓時，如圖14所示， 由於被頂接於閥頂接部45a的閥本體42反向推壓而使閥 @ 本體1 2朝後端側移動，栓塞1之閥機構成爲開放狀態。 如此則，液體燃料由栓塞1之噴嘴11b被噴出之同時，該 液體燃料通過插座2之彈性體保持器48最後被供給至燃 料受容部9。 另外，由插座2取下栓塞1時，由插座2拔出栓塞1 時，如圖1 3所示，首先，栓塞1之閥本體1 2朝前端側移 動，栓塞1之閥機構成爲關閉狀態。更進一步將栓塞1由 插座2拔出時，插座2之閥本體42會朝前端側移動，插 ◎ 座2之閥機構成爲關閉狀態。 更進一步將栓塞1由插座2拔出時，相對於噴嘴導引 部3 1，噴嘴1 1 b會朝後端側移動，如圖12所示，當噴嘴 — 11b之導引部用凹部Uf位於噴嘴嵌合部31b之位置時， 噴嘴嵌合部31b被嵌入噴嘴lib之導引部用凹部Ilf。如 此則，噴嘴導引部31再度被固定於噴嘴ub，可使噴嘴 lib不會突出於噴嘴導引部31。 關於上述具有噴嘴導引部31的栓塞1，僅在插座2之 -26- 201025714 辨識手段與栓塞1之辨識手段一致，或者插座2之內徑及 外徑，和栓塞1之噴嘴lib與縮徑部31c之縮徑部31c間 之間隙成爲一致之情況下，才可使噴嘴1 1 b突出於噴嘴導 引部31，可使栓塞1連接於插座2。 - 另外，插座2之辨識手段與栓塞1之辨識手段不一致 . ，或者插座2之內徑及外徑，和栓塞1之噴嘴lib與縮徑 部3 1 c之縮徑部3 1 C間之間隙不一致之情況下，無法使噴 φ 嘴11b突出於噴嘴導引部31，無法將栓塞1連接於插座2 。另外，欲連接對於噴嘴lib呈現過大之插座時，例如設 於噴嘴1 1 b外徑側的噴嘴導引部3 1、例如形成於縮徑部 31c前端側之水平部等會卡住插座插入口周緣部，噴嘴 lib無法插入插座內部，可保持閥機構之關閉狀態，可抑 制液體燃料之流出。 以下以內部氣化型DMFC爲例說明本發明之聯結器3 適用的燃料電池5。圖1 5表示本發明之燃料電池5之一例 φ 之斷面圖。燃料電池5主要由構成發電部之燃料電池芯7 ’燃料收容部8，以及具有省略圖式之插座2之燃料受容 部9所構成。另外，具有省略圖式之插座2之燃料受容部 ' 9 ’係例如圖1所示，設置於燃料收容部8之下面側。 燃料電池芯7具有膜電極組合體（MEA: Membrane ElecUode Assembly)，其由以下構成：陽極觸媒層71與 陽極氣體擴散層72所構成之陽極（燃料極）；陰極觸媒 層73與陰極氣體擴散層74所構成之陰極（氧化劑極/空 氣極）：及被陽極觸媒層71與陰極觸媒層73所夾持之質 -27- 201025714 子（proton (氫離子））傳導性的電解質膜75。 包含於陽極觸媒層71與陰極觸媒層73之觸媒之例有 :鉑（Pt)，釕（Ru)，鍺（Rh)，銥（Ir)，餓（〇s) ，鈀（Pd)等之白金族單體，以及含有白金族元素之合金 等。具體地說，陽極觸媒層71較好是使用對甲醇或一氧 化碳具有强耐性之鉑一釕（Pt-Ru )或鉑一鉬（Pt-Μο )等 · ，陰極觸媒層73較好是使用白金或鉛一鎳（Pt-Ni )等。 另外，也可以使用如碳材料之導電性擔持體之擔持觸媒， @ 或無擔持觸媒。 構成電解質膜75之質子傳導性材料之例有：例如具 有擴酸基的全氟礎酸聚合物之氟系樹脂（Nafion (商品名 ，杜邦工司製）或Flemion (商品名，旭玻璃公司製）等 )，具有磺酸基之碳氫系樹脂，鎢酸與磷鎢酸等之無機物 等。但是，並不限定於該等。 積層於陽極觸媒層71之陽極氣體擴散層72，除了將 燃料均勻供給至陽極觸媒層71之功能之外，也兼作爲陽 © 極觸媒層71之帶電體。另方面’積層於陰陰極觸媒層73 之陰極氣體擴散層74，除了將氧化劑均勻供給至陰極觸媒 層73之功能之外，也兼作爲陰極觸媒層73之帶電體。於 陽極氣體撗散層72被積層有陽極導電層76，於陰極氣體 擴散層74被積層有陰極導電層77。 陽極導電層76與陰極導電層77，係由例如金等導電 性金屬材料所構成的網狀物或多孔質膜'或薄膜等所構成 。另外，在電解質膜75與陽極導電層76之間’以及電解 -28- 201025714 質膜75與陰極導電層77之間，介設有橡膠製的〇環78 、79，藉以防止來自燃料電池芯7之燃料洩漏或氧化劑洩 漏。 在燃料收容部8內部充塡有例如甲醇燃料做爲液體燃 ' 料F。此外，燃料收容部8在燃料電池芯7側被開口，而 - 在該燃料收容部8之開口部與燃料電池芯7之間設有氣體 選擇穿透膜52。氣體選擇摻透膜52爲僅透過液體燃料F φ 之氣化成分，而不使液體成分透過之氣液分離膜。此種氣 體選擇摻透膜52之構成材料之例有：如聚四氟乙烯等氟 樹脂。其中，所謂液體燃料F之氣化成分，在使用甲醇水 溶液做爲液體燃料F時，係指甲醇的氣化成分與水之氣化 成分所構成之混合氣體，使用純甲醇時係指甲醇之氣化成 分。 在陰極導電層77上被積層有保濕層53，再於其上有 表面層54之積層。表面層54具有調節氧化劑、亦即空氣 φ 之取入量之功能，其調節法係藉由變更形成於表面層54 之空氣導入口 5 4a之個數與大小等來進行。保溼層53含 浸著在陰極觸媒層73產生之一部分水，而具有抑制水的 * 蒸散之功能’以及藉由對陰極氣體擴散層74均勻導入氧 化劑’而亦具有促進氧化劑對陰極觸媒層73之均勻擴散 之功能。保溼層53，係由例如多孔質構造之構件所構成， 具體的構成材料有聚乙烯或聚丙烯之多孔質體等。 在燃料收容部8上被積層的氣體選擇摻透膜52、燃料 電池芯7、保溼層53及表面層54，係藉由覆蓋例如不銹 -29- 201025714 鋼製之覆蓋物55予以保持。覆蓋物55,係在與形成於表 面層54之空氣導入某54a相對應的部分設有開口 55a。另 外’在燃料收容部8設有接受覆蓋物55的棘爪55b的平 台（terrace) 8a，藉由在該平台8a嵌入棘爪55b而使全 體藉由覆蓋物55保持成一體。 在具有上述構成之燃料電池5中，燃料收容部8內之 液體燃料F(例如甲醇水溶液）被氣化，而該氣化成分穿 過氣體選擇摻透膜52被供給至燃料電池芯7。在燃料電池 芯7內’液體燃料F之氣化成分被陽極氣體擴散層72擴 散而供給至陽極觸媒層71。被供給至陽極觸媒層71之氣 化成分產生例如以下式（1 )所示之甲醇的內部改質反應 CH3〇H + H20-> C〇2 + 6H+ + 6e' ...... ( 1 ) 另外，使用純甲醇爲液體燃料F時，因爲由燃料收容 部8不供給水蒸氣，所以可以使陰極觸媒層73所產生之 水或電解質膜75中之水與甲醇反應以產生上述式（1)之 內部改質反應，或不依賴上述式（1)之內部改質反應而 利用不需要水之其他反應機構產生內部改質反應。 內部改質反應所產生之質子（H+ )將於電解質膜75 中傳導’而到達陰極觸媒層73。由表面層54之空氣導入 口 5 4a取入之空氣（氧化劑）會將保溼層53、陰極導電層 77、陰極氣體擴散層74擴散，而被供給至陰極觸媒層73 -30- 201025714 。供給到陰極觸媒層73之空氣會使以下式（2 )所示之反 應產生： (3/2)〇2 + 6H+ + 6e'-^-3H2〇 ...... ( 2 ) • 隨著基於上述反應之發電反應之進行，燃料收容部8 內之液體燃料F (例如甲醇水溶液或純甲醇）被消耗。當 φ 燃料收容部8內之液體燃料F用磬時，發電反應即停止， 因此’在該時間點或在其以前的時間點由盒4對燃料收容 部8內供給液體燃料。來自盒4之液體燃料之供給，係如 上述說明，藉由將盒4側之栓塞1插入燃料電池5側之插 座2而被實施。 以上係對本發明的燃料電池用栓塞、燃料電池用聯結 器加以說明，惟本發明的燃料電池用栓塞、燃料電池用聯 結器並非限定於上述實施形態本身，在實施階段中，可以 φ 在不跳脫該要旨的範圍內變更構成要件之形態而具體化。 另外’利用上述實施形態所揭示的多種構成要件的適當組 合，可以形成各種發明。 * 例如，也可以由實施形態所示之全部構成要素刪除幾 個構成要素。另外’例如做爲燃料電池，雖以小型化被進 展的被動型DMFC爲適合，但是只要至少具備本發明的燃 料電池用聯結器中之燃料電池用插座，液體燃料係透過該 燃料電池用插座供給者，則對於其方式與機構等並無任何 限定。 -31 - 201025714 〔產業上之可利用性〕 本發明之燃料電池用栓塞，係具有噴嘴導引部3 1，其 僅在被連接於具有適應性之燃料電池用插座之情況下才使 噴嘴1 1 b突出者，因此，僅在被連接於具有適應性之燃料 電池用插座之情況下才使兩者之閥本體頂接，而可設定閥 機構成爲開放狀態。例如即使燃料電池用插座之插入口遠 大於噴嘴，有可能錯誤插入噴嘴之情況下，藉由噴嘴導引 部之卡在該燃料電池用插座之插入口之周緣部，可以抑制 噴嘴之突出，可以抑制兩者之閥本體之頂接，可抑制閥機 構之成爲開放狀態。因此，可抑制液體燃料對外部之流出 ，可構成爲具有安全性、信賴性佳者。此種安全性、信賴 性佳之燃料電池用栓塞可適用於燃料電池用聯結器，該燃 料電池用聯結器則用於對以行動電子機器爲始之各種電子 機器之電源、亦即燃料電池供給液體燃料者。 【圖式簡單說明】 圖1表示裝配有本發明之燃料電池用栓塞的燃料盒， 以及裝配有連接著本發明之燃料電池用栓塞的燃料電池用 插座之燃料電池之槪略圖。 圖2表示本發明之燃料電池用栓塞，以及連接著該燃 料電池用栓塞的燃料電池用插座之分離狀態之斷面圖。 圖3表示嵌合構件與嵌合部按壓構件之一例的外觀圖 -32- 201025714 圖4表示嵌合構件與嵌合部按壓構件之另一例的 圖。 圖5表示辨識構件之一例的外觀圖。 圖6表示連接初期之狀態的斷面圖。 、 圖7表示連接中途之由噴嘴之導引部用凹部1 If使嵌 - 合構件之噴嘴嵌合部被取下之狀態的斷面圖。 圖8表示連接中途之燃料電池用插座之閥機構成爲開 φ 放狀態之狀態的斷面圖。 圖9表示燃料電池用栓塞之閥機構成爲開放狀態、成 爲連接狀態時之狀態的斷面圖。 圖10表示本發明之另一燃料電池用栓塞，以及連接 著該燃料電池用栓塞的燃料電池用插座之分離狀態之斷面 圖。 圖11表示噴嘴導引部之一例的外觀圖及平面圖。 圖12表示連接初期之狀態的斷面圖。 φ 圖13表示連接中途之燃料電池用插座之閥機構成爲 開放狀態之狀態的斷面圖。 圖14表示燃料電池用栓塞之閥機構成爲開放狀態、 * 成爲連接狀態時之狀態的斷面圖。 圖15表示本發明之燃料電池用聯結器適用的燃料電 池之一例之斷面圖。 【主要元件符號說明】 1 :燃料電池用栓塞 -33- 201025714 2 :燃料電池用插座 3 :燃料電池用聯結器 4 :燃料盒 5 :燃料電池 6 :盒本體 ‘ 7 :燃料電池芯（發電部） - 8 :燃料收容部 9 :燃料受容部 @ 1 1 :栓塞本體 1 1 a :底座部 1 1 b :噴嘴 1 1 c :支撐筒部 1 1 d :密封凹部 1 1 e :燃料噴出口 1 If :導引部用凹 1 lg :導引部用溝部 @ 12 :閥本體 12a :前端側閥柱部 1 2b :閥頭部 12c :後端側閥柱部 1 3 :按壓帽部 1 4 :噴嘴導引部 1 5 :閥保持器 1 5b :連通孔 -34- 201025714 1 6 ·_ Ο 環 1 7 : Ο 環 1 8 :閥用彈性體 19 :導引部用彈性體 - 2 1 :筒狀本體 - 2 1 a :凹部 2 1 b :溝部 φ 22 :嵌合構件 22a :噴嘴嵌合部 22b :本體嵌合部 2 2 c :縮徑部 22d :平面部 22e :溝部 2 2 f :缺口部 23 :嵌合部按壓構件 φ 24 :辨識構件 24a :板狀部 24b :凸部 ' 31 :噴嘴導引部 3 1 a :本體部 3 1 b :噴嘴嵌合部 3 1 c :縮徑部 3 1 d :缺口部 3 1 e :平面部 -35 201025714 3 1 f :外壁部 3 1 g :支撐筒部嵌合部 41 :插座本體 41 a :噴嘴插入口 4 1 b :辨識凸部 ' 42 :閥本體 -42a :前端側閥柱部 42b :閥頭部 參 42c :後端側閥柱部 43 :前端側筒部 44 :中間筒部 45 :後端側筒部 45a :閥頂接部 4 5 b :流通孔 46 : Ο 環 47 :閥用彈性體 · 48 :彈性體保持器 49 :保持器支撐構件 5 1 :支撐構件用彈性體 * -36-31d, the appearance is set to C-shaped. By the C-shape having the notch portion 31d, the diameter of the elastic deformation can be easily increased. The main body portion 3 1 a 'Q has, for example, a flat portion 3 1 e that is pressed against the distal end side of the elastic portion 1 9 ' for the guide portion; and an outer diameter side of the flat portion 3 1 e extends toward the distal end side. The outer wall portion 3 1 f for preventing the inclination of the nozzle guide portion 31 is formed in contact with the inner surface of the support cylinder portion 11c. The nozzle fitting portion 31b' is protruded from the inner diameter side of the main body portion 31a, and is disposed, for example, at equal intervals in the circumferential direction. On the outer diameter side of each nozzle fitting portion 3 1 b, the body portion 3 1 a is strictly referred to as the front end side of the flat portion 3 1 e , and a reduced diameter portion 3 1 c having a reduced diameter from the front end side to the rear end side is formed. In addition, the nozzle fitting portion 31b' reduced diameter portion 31c is the same as the nozzle fitting portion 22a and the reduced diameter portion 22c of the fitting member 22 shown in Figs. 3 and 4, and thus the description thereof is omitted. Further, a horizontal portion is formed on the front end side of the reduced diameter portion 3 1 c toward the outer diameter side to form a horizontal portion. By setting in the horizontal direction, even if, for example, the insertion opening of the socket is much larger than the nozzle lib and there is a possibility of erroneous insertion, the horizontal portion can be caught at the edge of the insertion opening of the socket, and the valve body of both can be suppressed. The top connection prevents the valve mechanism from being opened, and can suppress the outflow of the liquid fuel to the outside - 24 - 201025714, and can be constructed to be safe and reliable. On the outer diameter side of the main body portion 31a, for example, the support tubular portion fitting portion 31g is formed in conformity with the arrangement in the circumferential direction of the nozzle fitting portion 31b. The support tubular portion fitting portion 31g is movably fitted into the guide portion groove portion 11g formed in the axial direction of the support tubular portion Uc, so that the nozzle guide can be defined. At the same time, the rotation of the circumference can be suppressed. Φ has the plug 1 of the nozzle guide portion 31, and the nozzle fitting portion 31b and the reduced diameter portion 3 1 c are respectively the nozzle fitting portion 22a 'the reduced diameter portion 22c of the fitting member 22 shown in Figs. 3 and 4 Similarly, the flat portion 31e corresponds to the flat portion 22d of the fitting member 22 shown in Figs. 3 and 4, and supports the tubular fitting portion 31g and the body fitting portion 22b of the fitting member 22 shown in Figs. (In this case, the groove portion 1 1 g for the guide portion of the support cylinder portion 1 1 c corresponds to the recess portion 21a of the tubular body 21 shown in Fig. 2). The plug 1 having the nozzle guide portion 31 and the socket 2 can be connected as follows. First, when the plug 1 is to be connected to the socket 2 as shown in FIG. 10, as shown in FIG. 12, the identification means of the socket 2, that is, the identification convex portion 4 1 b is attached to the plug 1 The reduced diameter portion 31c on the inner diameter side of the nozzle guide portion 31. At this time, the seal recessed portion lid of the nozzle lib is fitted into the elastomer holder 48 of the socket 2, and the nozzle 11b and the elastomer holder 48 are sealed to suppress the outflow of the liquid fuel. Further, when the plug 1 is pushed toward the socket 2, as shown in FIG. 13, the reduced diameter portion 31c is pushed by the front end side of the -25-201025714 by the reverse pressing of the identification convex portion 41b of the socket 2, and the main body portion is pressed. 3 1 a presents an expansion. When the nozzle guide portion 31 of the guide portion recessed portion Ilf is inserted into the nozzle lib, the nozzle guide portion 31 is released from the nozzle guide portion 31, and the nozzle lib can be protruded from the nozzle guide portion 31. . Further, when the nozzle lib is further inserted as described above, the valve body 42 of the socket 2 is moved toward the rear end side of the valve bodies 12 and 42 which are adjacent to each other, and the valve mechanism of the socket 2 is opened. - When the plug 1 is further pushed toward the socket 2, as shown in FIG. 14, the valve body 2 is moved toward the rear end side by the valve body 42 that is abutted against the valve top portion 45a. The valve mechanism of the plug 1 is opened. In this manner, while the liquid fuel is ejected from the nozzle 11b of the plug 1, the liquid fuel is finally supplied to the fuel receiving portion 9 through the elastomer holder 48 of the socket 2. Further, when the plug 1 is removed from the socket 2, when the plug 1 is pulled out from the socket 2, as shown in Fig. 13, first, the valve body 12 of the plug 1 is moved toward the distal end side, and the valve mechanism of the plug 1 is closed. Further, when the plug 1 is pulled out from the socket 2, the valve body 42 of the socket 2 is moved toward the front end side, and the valve mechanism of the insertion seat 2 is closed. Further, when the plug 1 is pulled out from the socket 2, the nozzle 1 1 b moves toward the rear end side with respect to the nozzle guide portion 3 1, as shown in Fig. 12, when the guide portion of the nozzle - 11b is located with the recess Uf At the position of the nozzle fitting portion 31b, the nozzle fitting portion 31b is fitted into the guide portion recessed portion 11f of the nozzle lib. As a result, the nozzle guide portion 31 is again fixed to the nozzle ub so that the nozzle lib does not protrude from the nozzle guide portion 31. Regarding the above-mentioned plug 1 having the nozzle guiding portion 31, only the identification means of the socket 2 is -26-201025714, and the identification means of the plug 1 is identical, or the inner diameter and the outer diameter of the socket 2, and the nozzle lib and the diameter of the plug 1 are reduced. When the gap between the reduced diameter portions 31c of the portion 31c is matched, the nozzle 1 1 b can be protruded from the nozzle guide portion 31, and the plug 1 can be connected to the socket 2. - In addition, the identification means of the socket 2 does not coincide with the identification means of the plug 1, or the inner diameter and the outer diameter of the socket 2, and the gap between the nozzle lib of the plug 1 and the reduced diameter portion 3 1 C of the reduced diameter portion 3 1 c In the case of inconsistency, the nozzle φ11b cannot protrude from the nozzle guide 31, and the plug 1 cannot be connected to the socket 2. In addition, when the socket which is too large for the nozzle lib is to be connected, for example, the nozzle guide portion 31 provided on the outer diameter side of the nozzle 1 1 b, for example, the horizontal portion formed on the front end side of the reduced diameter portion 31c may catch the socket insertion opening. At the peripheral portion, the nozzle lib cannot be inserted into the inside of the socket, and the valve mechanism can be kept closed, thereby suppressing the outflow of the liquid fuel. Hereinafter, the fuel cell 5 to which the coupler 3 of the present invention is applied will be described by taking an internal gasification type DMFC as an example. Fig. 15 is a cross-sectional view showing an example of φ of the fuel cell 5 of the present invention. The fuel cell 5 is mainly composed of a fuel cell core 7' fuel accommodating portion 8 constituting a power generating portion, and a fuel receiving portion 9 having a socket 2 of the drawings. Further, the fuel receiving portion '9' having the socket 2 of the drawings is provided on the lower surface side of the fuel containing portion 8, as shown in Fig. 1, for example. The fuel cell core 7 has a membrane electrode assembly (MEA: Membrane ElecUode Assembly) which is composed of an anode (fuel electrode) composed of an anode catalyst layer 71 and an anode gas diffusion layer 72, a cathode catalyst layer 73 and a cathode gas. Cathode (oxidant electrode/air electrode) composed of diffusion layer 74: and electrolyte membrane -27-201025714 (proton) conductive by the anode catalyst layer 71 and the cathode catalyst layer 73 75. Examples of the catalyst contained in the anode catalyst layer 71 and the cathode catalyst layer 73 are: platinum (Pt), ruthenium (Ru), rhodium (Rh), iridium (Ir), hungry (〇s), palladium (Pd). Such as platinum family monomers, and alloys containing platinum group elements. Specifically, the anode catalyst layer 71 is preferably a platinum-platinum (Pt-Ru) or a platinum-molybdenum (Pt-Μο) or the like which is highly resistant to methanol or carbon monoxide, and the cathode catalyst layer 73 is preferably used. Platinum or lead-nickel (Pt-Ni). Further, it is also possible to use a supporting catalyst such as a conductive support of a carbon material, @ or a non-supporting catalyst. Examples of the proton conductive material constituting the electrolyte membrane 75 include, for example, a fluorine-based resin of a perfluoroacid polymer having an acid-expanding group (Nafion (trade name, manufactured by DuPont) or Flemion (trade name, manufactured by Asahi Glass Co., Ltd.) (a), etc., a hydrocarbon-based resin having a sulfonic acid group, an inorganic substance such as tungstic acid or phosphotungstic acid, or the like. However, it is not limited to these. The anode gas diffusion layer 72 laminated on the anode catalyst layer 71 serves as a charged body of the anode/electrode catalyst layer 71 in addition to the function of uniformly supplying the fuel to the anode catalyst layer 71. On the other hand, the cathode gas diffusion layer 74 laminated on the cathode catalyst layer 73 serves as a charged body of the cathode catalyst layer 73 in addition to the function of uniformly supplying the oxidant to the cathode catalyst layer 73. An anode conductive layer 76 is laminated on the anode gas diffusion layer 72, and a cathode conductive layer 77 is laminated on the cathode gas diffusion layer 74. The anode conductive layer 76 and the cathode conductive layer 77 are composed of a mesh or a porous film 'or a thin film made of a conductive metal material such as gold. In addition, between the electrolyte membrane 75 and the anode conductive layer 76 and between the plasma 28 and the cathode conductive layer 77, a rubber ring 78, 79 is interposed between the electrolyte membrane 75 and the cathode conductive layer 77, thereby preventing the fuel cell core 7 from being drawn. Fuel leak or oxidant leak. Inside the fuel containing portion 8, for example, a methanol fuel is charged as a liquid fuel F. Further, the fuel accommodating portion 8 is opened at the fuel cell core 7 side, and a gas selective permeable membrane 52 is provided between the opening portion of the fuel accommodating portion 8 and the fuel cell core 7. The gas selective doping film 52 is a gas-liquid separation film that transmits only the vaporized component of the liquid fuel F φ without passing the liquid component. Examples of the constituent material of such a gas-selective doping film 52 include a fluororesin such as polytetrafluoroethylene. The gasification component of the liquid fuel F is a mixed gas composed of a vaporized component of methanol and a vaporized component of water when a methanol aqueous solution is used as the liquid fuel F, and a methanol gas is used when pure methanol is used. Ingredients. A humectant layer 53 is laminated on the cathode conductive layer 77, and a layer of the surface layer 54 is laminated thereon. The surface layer 54 has a function of adjusting the amount of oxidant, i.e., the amount of intake of air φ, and the adjustment method is performed by changing the number and size of the air introduction ports 504 formed on the surface layer 54. The moisturizing layer 53 is impregnated with a portion of the water generated in the cathode catalyst layer 73, and has a function of suppressing the evapotranspiration of water 'and a uniform introduction of the oxidizing agent to the cathode gas diffusion layer 74' to promote the oxidizing agent to the cathode catalyst layer. The function of uniform diffusion of 73. The moisture retaining layer 53 is made of, for example, a member having a porous structure, and a specific constituent material is a porous body of polyethylene or polypropylene. The gas selective doping film 52, the fuel cell core 7, the moisture retaining layer 53, and the surface layer 54 which are laminated on the fuel containing portion 8 are held by a cover 55 made of, for example, stainless steel -29-201025714. The cover 55 is provided with an opening 55a at a portion corresponding to the air introduction 54a formed in the surface layer 54. Further, the fuel accommodating portion 8 is provided with a terrace 8a for receiving the pawl 55b of the cover 55, and the entire body is held integrally by the cover 55 by inserting the pawl 55b on the platform 8a. In the fuel cell 5 having the above configuration, the liquid fuel F (e.g., aqueous methanol solution) in the fuel containing portion 8 is vaporized, and the vaporized component is supplied to the fuel cell core 7 through the gas selective doping film 52. In the fuel cell 7, the vaporized component of the liquid fuel F is diffused by the anode gas diffusion layer 72 and supplied to the anode catalyst layer 71. The gasification component supplied to the anode catalyst layer 71 generates, for example, an internal reforming reaction of methanol represented by the following formula (1) CH3〇H + H20-> C〇2 + 6H+ + 6e' ... (1) When pure methanol is used as the liquid fuel F, since water vapor is not supplied from the fuel containing portion 8, the water generated in the cathode catalyst layer 73 or the water in the electrolyte membrane 75 can be reacted with methanol to produce the above. The internal reforming reaction of the formula (1) or the internal reforming reaction of the above formula (1) does not rely on other reaction mechanisms that do not require water to generate an internal reforming reaction. The proton (H+) generated by the internal reforming reaction will conduct in the electrolyte membrane 75 and reach the cathode catalyst layer 73. The air (oxidant) taken in from the air introduction port 54a of the surface layer 54 diffuses the moisture retaining layer 53, the cathode conductive layer 77, and the cathode gas diffusion layer 74, and is supplied to the cathode catalyst layer 73 -30-201025714. The air supplied to the cathode catalyst layer 73 causes a reaction represented by the following formula (2) to occur: (3/2) 〇 2 + 6H + + 6e'-^-3H2 〇 ( 2 ) • The liquid fuel F (for example, an aqueous methanol solution or pure methanol) in the fuel containing portion 8 is consumed by the progress of the power generation reaction based on the above reaction. When the liquid fuel F in the φ fuel accommodating portion 8 is used, the power generation reaction is stopped, so that the liquid fuel is supplied to the fuel accommodating portion 8 from the cartridge 4 at this point of time or at a previous time. The supply of the liquid fuel from the cartridge 4 is carried out by inserting the plug 1 on the side of the cartridge 4 into the socket 2 on the side of the fuel cell 5 as described above. In the fuel cell plug and the fuel cell coupler of the present invention, the fuel cell plug and the fuel cell coupler of the present invention are not limited to the above-described embodiment, and in the implementation stage, φ may not jump. In the scope of the purpose, the form of the constituent elements is changed and embodied. Further, various inventions can be formed by appropriate combination of various constituent elements disclosed in the above embodiments. * For example, several components may be deleted from all the components shown in the embodiment. In addition, it is suitable as a fuel cell, for example, a passive DMFC that is developed to be miniaturized. However, as long as at least the fuel cell socket in the fuel cell coupler of the present invention is provided, the liquid fuel is supplied through the fuel cell socket. There is no limit to the way, the organization, and the like. -31 - 201025714 [Industrial Applicability] The plug for a fuel cell of the present invention has a nozzle guide portion 3 1, which is only provided when it is connected to an adaptable fuel cell socket. 1 b is a prominent person. Therefore, the valve body of the two can be brought into contact only when connected to an adaptable fuel cell socket, and the valve mechanism can be set to be in an open state. For example, even if the insertion port of the fuel cell socket is much larger than the nozzle, the nozzle may be inserted into the peripheral portion of the insertion port of the fuel cell socket by the nozzle guide portion, thereby suppressing the protrusion of the nozzle. By suppressing the top connection of the valve bodies of both, it is possible to suppress the valve mechanism from being opened. Therefore, it is possible to suppress the outflow of the liquid fuel to the outside, and it is possible to provide safety and reliability. Such a fuel cell plug for safety and reliability can be applied to a fuel cell coupler, and the fuel cell coupler is used to supply a liquid to a power source of various electronic devices starting from a mobile electronic device, that is, a fuel cell.
