200847509 九、發明說明： 【發明所屬之技術領域】 本發明係有關一種電極結構以及使用該電極結構之燃 料電池，尤其是指一種利用至少一筒狀電極結構透過串聯 或並聯以形成燃料電池，進而製成隨身型電池尺寸，以利 用於市售電器產品之電池座以供應電力之一種電極結構以 及使用該電極結構之燃料電池。 【先前技術】 請參閱圖一所示，該圖係為習用之燃料電池結構式意 圖。該燃料電池之電極結構係屬於平板式構造’通常以複 數個之電極結構攀聯使用。該電極結構1之兩侧分別具有 複數個通道11與12。其中，通道11係可通入燃料，燃料 經過膜電極組10之觸媒層100催化解離為氫離子與電子， 氫離子通過質子交換膜101到達該電極結構之負極14，而 電子則經過正極13至外部負載作功之後，回到該電極結構 之負極14。另外，通道12通過氧氣或者是空氣，並透過 電極結構之負極14端之觸媒層102催化與由負載回來之電 子結合而形成水，再經過通道12排出。 由於圖一之習用燃料電池電極結構1多為平板式結 構，與目前市售電器產品之電池座規格不同，無法直接用 於市售電器之電池座中。雖然在中華民國專利公告號第 1270995已經揭露一種”具備乾電池外型的燃料電池”， 然而在該項專利技術中，其電極結構係為利用平板式結 5 200847509 構。因此，如需要經由串聯產生高電壓輸出，電極結構以 及集電板之個數必須增加，如此一來電池的體積以及重量 也會隨之增加，進而降低燃料電池之便利性與可攜性。此 外，一般習用之燃料電池，其燃料必須利用幫浦等輔助裝 置供應，這些額外之設備益增加燃料電池之體積與重量， 而且也增加燃料電池之成本。 綜合上述，因此亟需一種電極結構以及使用該電極結 構之料電池來解決習用技術所產生之問題。 【發明内容】 本發明之主要目的係為提供一種電極結構，其係具有 筒狀結構，以增加燃料電池之反應面積，以降低燃料電池 串聯或並聯使用時之體積。 本發明之主要目的係為提供一種燃料電池，其係可以 製作成隨身型電池尺寸，並可直接使用於市售電器產品， 以增加燃料電池利用之場合。 本發明之次要目的係為提供一種燃料電池，其係可以 讓使用者隨時補充燃料，以增加燃料電池之可攜性以及方 便性。 本發明之另一目的係為提供一種燃料電池，其係可以 讓使用者任意更換燃料電池内之任一老化之電極結構，以 維持燃料電池之發電效率，進而減輕環保之負擔。 本發明之又一目的，係為提供一種電極結構，其膜電 極組係呈現摺皺結構，以增加反應面積，增加發電效率。 200847509 為了達到上述之目的本發明提供一種電極結構，包 括：一膜電極組，其係呈筒狀結構，該膜電極組内具有一 容置空間，以提供容置一第一反應物；一第一集電體，其 係設置於該容置空間之表面上；以及一第二集電體，其係 設置於該膜電極組之外表面以與一第二反應物相接觸。 較佳的是，該膜電極組之徑向截面係呈現一摺皺結構。 較佳的是，該第一集電體之上方以及下方分別具有一 上隔板以及一下隔板，以將該容置空間隔成密閉空間。其 中該上隔板上具有一凸部，以及該下隔板上具有一凹部。 該下隔板上更設置有一反應物補充介面。 為了達到上述之目的，本發明更提供一種燃料電池， 包括：一發電單元，其係具有一電極結構，該電極結構具 有：一膜電極組，其係呈筒狀結構，該膜電極組内具有一 容置空間，以提供容置一第一反應物；一第一集電體，其 係設置於該容置空間之表面上；以及一第二集電體，其係 設置於該膜電極組之外表面以與一第二反應物相接觸；以 及一對電極，其係分別設置於該發電單元之兩側且分別與 該第一集電體以及該第二集電體偶接，以傳導該發電單元 所產生之電子。 較佳的是，該燃料電池係為一乾電池。 較佳的是，該第二集電體之外側更設置有一電池殼 組，其係可拆卸。該電池殼組更具有：一外殼體，其係罩 覆於該第二集電體之外部；以及一蓋體，其係與該外殼體 之一端相連接，該蓋體係可拆卸。 較佳的是，發電單元之底部更具有第一反應物補充介 7 200847509 面0 為了達到上述之目的本發明更提供一種燃料電池，包 括：一發電單元，其係具有複數個電極結構，該複數個電 極結構可以一連接方式相互偶接，每一個電極結構具有： 一膜電極組，其係呈筒狀結構，該膜電極組内具有一容置 空間，以提供容置一第一反應物；一第一集電體，其係設 置於該容置空間之表面上；以及一第二集電體，其係設置 於該膜電極組之外表面以與一第二反應物相接觸；以及一 對電極，其係分別設置於該發電單元之兩侧以傳導該發電 單元所產生之電子。 【實施方式】 為使貴審查委員能對本發明之特徵、目的及功能有 更進一步的認知與暸解，下文特將本發明之裝置的相關細 部結構以及設計的理念原由進行說明，以使得審查委員可 以了解本發明之特點，詳細說明陳述如下： 請參閱圖二A與圖二B所示，其中圖二A係為本發明 電極結構之第一實施例俯視示意圖；圖二B係為本發明電 極結構之第一實施例剖面示意圖。該電極結構3具有一膜 電極組30、一第一集電體31以及一第二集電體32。該膜 電極組30，其係呈筒狀結構，該膜電極組30内具有一容 置空間300，以提供容置一第一反應物。在本實施例中該 筒狀結構係為圓筒，但實際上，並不以圓筒為限，例如： 橢圓形、矩形等亦可實施。該第一集電體31，其係設置於 該容置空間300之表面上。該第二集電體32，其係設置於 8 200847509 以與一第二反應物相接觸。該第-=物係驗體^是氣體之富氫㈣，例如：含醇類（如 .=1 =此為限)或含氫氣之燃料之燃料。而該第二反 應物係可為氧氣或者是空氣。 . %圖二Β所示’該電極結構3之底端，介於該第一集 3丄與該第二集電體32之間’更具有一隔板該隔 除了絕緣之用途外，更可以作為該容置空間之隔 〇 Ϊ更:=在=結構3之頂端’該第二集電體32之前 1 更;"置有—隔板33。以作為複數個電極結構3串聯時， ί ;

Description of the Invention: The present invention relates to an electrode structure and a fuel cell using the same, and more particularly to a fuel cell formed by using at least one cylindrical electrode structure in series or in parallel to form a fuel cell. An electrode structure for making a portable battery size to utilize a battery holder of a commercially available electric appliance to supply electric power and a fuel cell using the same. [Prior Art] Please refer to Figure 1, which is a structural diagram of a conventional fuel cell. The electrode structure of the fuel cell is of a flat type construction, which is usually used in combination with a plurality of electrode structures. The electrode structure 1 has a plurality of channels 11 and 12 on each side thereof. Wherein, the channel 11 is capable of passing fuel, and the fuel is catalytically dissociated into hydrogen ions and electrons through the catalyst layer 100 of the membrane electrode assembly 10, and the hydrogen ions pass through the proton exchange membrane 101 to reach the negative electrode 14 of the electrode structure, and the electrons pass through the positive electrode 13 After working to the external load, return to the negative electrode 14 of the electrode structure. Further, the passage 12 passes through oxygen or air and is catalyzed by the catalyst layer 102 at the end of the negative electrode 14 of the electrode structure to be combined with the electrons returned by the load to form water, which is then discharged through the passage 12. Since the electrode structure of the conventional fuel cell of Fig. 1 is mostly a flat plate structure, unlike the battery holder specifications of currently available electrical products, it cannot be directly used in the battery holder of a commercially available electric appliance. Although a "fuel cell having a dry battery appearance" has been disclosed in the Republic of China Patent Publication No. 1270995, in this patented technology, the electrode structure is constructed using a flat plate type 5 200847509.

In addition, in conventional fuel cells, the fuel must be supplied by an auxiliary device such as a pump. These additional devices increase the volume and weight of the fuel cell, and also increase the cost of the fuel cell. In summary, there is a need for an electrode structure and a battery using the electrode structure to solve the problems caused by conventional techniques.

In the case of a plurality of electrode structures 3 connected in series, ί; 3 between the insulating plates. Further, the first current collector 31 and the f: current collector 32 have - grooves (10), 320, respectively. Except for Figure 2, which is shown in Figure 2C, the figure is the same as: In this embodiment, the difference from the phase π of the second embodiment is that the spacers of the second current collector 32 are connected in series in the embodiment, and the accommodation space of the adjacent electrode structures 3 is referred to. Figure 3 is a schematic cross-sectional view of the electrode of the present invention.

The electrode structure 4 has a membrane electrode group 40, a first current collector 41 and a second current collector 42. The membrane electrode assembly 40 has a cylindrical structure, and the membrane electrode assembly 40 has an accommodating space 400 therein for providing a first reactant. In the present embodiment, the cylindrical structure is a cylinder, but in practice, it is not limited to a cylinder, and an example p such as an ellipse or a rectangle may be used. The first current collector 41 is disposed on a surface of the accommodating space 400. The second current collector 42 is disposed on the outer surface of the membrane electrode assembly 40 to be in contact with a second reactant. The first reactant and the second reactant are as described above and will not be described herein. An upper partition 44 and a lower partition 45 are disposed above and below the first current collector 41 to close one end of the accommodating space 400, so that the accommodating space 400 forms a sealed space. A protrusion 440 may be further disposed on the upper partition 44, and a recess 450 may be disposed on the lower partition 45 to facilitate connecting a plurality of electrode structures as shown in FIG. A reactant replenishing interface 43 is further disposed on the lower partition 45 to provide an interface through which the fuel can enter the accommodating space. The reactant replenishing interface can be a pressure valve, which is a conventional technique and will not be described herein. Further, an insulating plate 49 may be provided between the first current collector 41 and the second current collector 42. Please refer to FIG. 7B, which is a cross-sectional view showing a fourth embodiment of the electrode structure of the present invention. The basic structure of this embodiment is substantially the same as that of Fig. 7A, except that the structures of the first stage electric body 41 and the second current collector 42 are designed to be convenient in parallel. FIG. 8 is a cross-sectional view showing a fourth embodiment of the fuel cell of the present invention. In the present embodiment, a plurality of fuel cells 6 in the form of a dry battery are connected in series with each other as shown in Fig. 7A. The outer casing structure of the fuel cell 6 is as described above and will not be described herein. Since in Fig. 8, each of the electrode structures 4 is designed in a single module form, it is convenient for the user to replace any of the electrode structures. However, the above is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto.
