Hereinafter, an embodiment of the present invention will be described based on the drawings.

Fig. 1 shows a schematic configuration of an electrolyzed water generating apparatus 1 of the present embodiment. The electrolyzed water generating apparatus 1 can be used for the generation of household drinking and cooking water and the generation of dialysate for hemodialysis.

The electrolyzed water generating apparatus 1 includes an electrolytic cell 4 in which an electrolysis chamber 40 for supplying electrolyzed water is formed, an anode electric power supply body 41 and a cathode electric power supply body 42 which are disposed to face each other in the electrolysis chamber 40, and a separator 43 which is equipped It is provided between the anode power supply body 41 and the cathode power supply body 42. Other electrolytic cells may be provided on the upstream side or the downstream side of the electrolytic cell 4. Further, other electrolytic cells may be provided in parallel with the electrolytic cell 4. The same structure as that of the electrolytic cell 4 can be applied to the electrolytic cell separately provided.

The separator 43 divides the electrolysis chamber 40 into an anode chamber 40A on the anode power supply body 41 side and a cathode chamber 40B on the cathode power supply body 42 side. Water is supplied to the two chambers of the anode chamber 40A and the cathode chamber 40B of the electrolysis chamber 40, and a DC voltage is applied to the anode power supply body 41 and the cathode power supply body 42, whereby electrolysis of water occurs in the electrolysis chamber 40.

The separator 43 passes ions generated by the electrolysis, and the anode power supply body 41 and the cathode power supply body 42 are electrically connected via the separator 43. As the separator 43, for example, a solid polymer material composed of a fluorine-based resin material having a sulfonic acid group is used.

Neutral electrolytic hydrogen water and electrolytic oxygen water are produced in the electrolytic cell 4 having the separator 43 using a solid polymer material. Electrolysis is performed in the electrolysis chamber 40 through the water, whereby electrolytic hydrogen water in which hydrogen gas is dissolved is obtained in the cathode chamber 40B, and electrolytic oxygen water in which oxygen is dissolved is obtained in the anode chamber 40A.

The electrolyzed water generating apparatus 1 further includes a control unit 6 for controlling the electrolytic cell 4, a water inlet portion 7 provided on the upstream side of the electrolytic cell 4, and a water discharge portion 8 provided on the downstream side of the electrolytic cell 4.

The control unit 6 has, for example, a CPU (Central Processing Unit) that performs various arithmetic processing, information processing, and the like, and a memory or the like that stores programs and various information for the CPU operation.

A current detecting unit 44 is provided on the current supply line between the anode power supply body 41 and the control unit 6. The current detecting unit 44 may also be disposed on the current supply line between the cathode power supply body 42 and the control unit 6. The current detecting unit 44 detects the electrolysis current supplied to the power supply bodies 41, 42 and outputs a signal corresponding to the value to the control unit 6.

The control unit 6 performs feedback control of the voltage applied between the anode power supply body 41 and the cathode power supply body 42 based on the signal input from the current detecting unit 44. For example, when the electrolysis current is excessively large, the control unit 6 reduces the voltage, and when the electrolysis current is too small, the control unit 6 increases the voltage. Thereby, the electrolysis current supplied to the power supply bodies 41 and 42 can be appropriately controlled.

The water inlet portion 7 has a water supply pipe 71, a flow rate sensor 72, a branch portion 73, a flow rate adjusting valve 74, and the like. The water supply pipe 71 guides the water supplied to the electrolyzed water generating device 1 into the electrolysis chamber 40. The flow sensor 72 is disposed on the water supply pipe 71. The flow rate sensor 72 periodically detects the flow rate per unit time (hereinafter, simply referred to as "flow rate") F of the water supplied to the electrolysis chamber 40, and outputs a signal corresponding to the value to the control unit 6.

The branch portion 73 branches the water supply pipe 71 into two pipes of the water supply pipes 71a and 71b. The flow rate adjustment valve 74 connects the water supply pipes 71a, 71b to the anode chamber 40A or the cathode chamber 40B. Under the management of the control unit 6, the flow rate of the water supplied to the anode chamber 40A and the cathode chamber 40B is adjusted by the flow rate adjusting valve 74. In order to improve the water use efficiency, the flow rate adjustment valve 74 adjusts the flow rate of the water supplied to the anode chamber 40A and the cathode chamber 40B. As a result, a pressure difference sometimes occurs between the anode chamber 40A and the cathode chamber 40B.

In the present embodiment, since the flow rate sensor 72 is provided on the upstream side of the branch portion 73, the sum of the flow rate of the water supplied to the anode chamber 40A and the flow rate of the water supplied to the cathode chamber 40B, that is, the supply is detected.

The water discharge unit 8 has a flow path switching valve 81, a spout pipe 82, a drain pipe 83, and the like. The flow path switching valve 81 selectively connects the anode chamber 40A and the cathode chamber 40B with the spout pipe 82 or the drain pipe 83. When the electrolyzed water generating apparatus 1 is used to generate a dialysate for hemodialysis, the electrolyzed hydrogen water generated in the cathode chamber 40B is supplied to the reverse osmosis membrane module for filtration treatment via the spout pipe 82 and used to dilute the dialysis stock solution. Diluting device, etc.

The control unit 6 controls the polarity of the direct current voltage applied to the anode power supply body 41 and the cathode power supply body 42. For example, the control unit 6 accumulates the flow rate F of the water supplied to the electrolysis chamber 40 based on the signal input from the flow rate sensor 72, and switches to the anode power supply body 41 and the cathode power supply body 42 if the predetermined flow rate is reached. The polarity of the DC voltage. Along with this, the anode chamber 40A and the cathode chamber 40B are exchanged with each other. When the polarity of the DC voltage is switched, the control unit 6 causes the flow regulating valve 74 and the flow path switching valve 81 to operate in synchronization. Thereby, the cathode chamber 40B and the spout pipe 82 are always connected, and the electrolyzed hydrogen water generated in the cathode chamber 40B is discharged from the spout pipe 82.

Fig. 2 is an assembled perspective view of the electrolytic cell 4. The electrolytic cell 4 has a first outer casing piece 50 on the anode power supply body 41 side and a second outer casing piece 60 on the cathode power supply body 42 side. The first outer casing piece 50 and the second outer casing piece 60 which are disposed to face each other are fixedly joined to each other to form an electrolytic chamber 40 therein (refer to Fig. 1).

A laminate 45 in which the anode power supply body 41, the separator 43, and the cathode power supply body 42 are stacked is housed in the electrolytic chamber 40 of the electrolytic cell 4. The anode power supply body 41, the diaphragm 43, and the cathode power supply body 42 are each formed in a rectangular shape.

The anode power supply body 41 and the cathode power supply body 42 are each configured such that water can reciprocate in the thickness direction thereof. For the anode power supply body 41 and the cathode power supply body 42, a mesh metal such as a metal mesh can be applied. The mesh-shaped anode power supply body 41 and the cathode power supply body 42 sandwich the separator 43 and allow water to flow over the surface of the separator 43, thereby promoting electrolysis in the electrolytic chamber 40. In the present embodiment, as the anode power supply body 41 and the cathode power supply body 42, a power supply body in which a platinum plating layer is formed on the surface of a titanium metal mesh can be applied. The platinized layer prevents oxidation of titanium.

The anode power supply body 41 is provided with a terminal 41a that penetrates the first outer casing piece 50 and protrudes to the outside of the electrolytic cell 4. Similarly, the cathode power supply body 42 is also provided with a terminal 42a that penetrates the second outer casing piece 60 and protrudes to the outside of the electrolytic cell 4. A DC voltage is applied to the anode power supply body 41 and the cathode power supply body 42 via the terminals 41a and 42a.

In the present embodiment, a solid polymer material composed of, for example, a fluorine-based resin material having a sulfonic acid group is used for the separator 43. Neutral electrolyzed water is produced in the electrolytic cell 4 having the separator 43 using a solid polymer material. A plating layer 43a made of platinum is formed on both surfaces of the separator 43. The plating layer 43a is in contact with and electrically connected to the anode power supply body 41 and the cathode power supply body 42.

The separator 43 is sandwiched between the anode power supply body 41 and the cathode power supply body 42 in the electrolytic chamber 40. Therefore, the shape of the diaphragm 43 is maintained by the anode power supply body 41 and the cathode power supply body 42. According to the holding structure of the diaphragm 43, the majority of the stress resulting from the pressure difference generated between the anode chamber 40A and the cathode chamber 40B is borne by the anode power supply body 41 and the cathode power supply body 42, thereby reducing the stress applied to the diaphragm 43. . Thereby, even if the electrolyzed water generating apparatus 1 is operated in a state where a large pressure difference is generated between the anode chamber 40A and the cathode chamber 40B, a large stress is not generated in the diaphragm 43. Therefore, damage of the diaphragm 43 can be suppressed, and water use efficiency can be easily improved.

Further, since the diaphragm 43 is sandwiched between the anode power supply body 41 and the cathode power supply body 42, the contact resistance between the plating layer 43a of the separator 43 and the anode power supply body 41 and between the plating layer 43a and the cathode power supply body 42 can be reduced, and voltage drop can be suppressed. . Thereby, electrolysis in the electrolysis chamber 40 can be promoted, and electrolytic hydrogen water having a high hydrogen solubility concentration can be generated.

A seal member 46 for preventing water from leaking from the joint surface of the first outer shell piece 50 and the second outer shell piece 60 is provided outside the outer peripheral edge of the anode power supply body 41 and the cathode power supply body 42. The outer peripheral portion of the diaphragm 43 is sandwiched by the sealing member 46.

Each of the outer shell sheets 50 and 60 is formed in a rectangular shape elongated in the longitudinal direction V along the flow of water in the electrolytic chamber 40. Along with this, the electrolysis chamber 40 is formed in a rectangular shape elongated in the longitudinal direction V. Due to such an elongated electrolytic chamber 40, the flow path in the electrolytic cell 4 becomes long. As a result, the hydrogen gas generated in the cathode chamber 40B can be easily dissolved in the water in the cathode chamber 40B to increase the hydrogen dissolution concentration.

L-shaped joints 91, 92, 93, and 94 are provided in the electrolytic cell 4. The joints 91, 92 are attached to the lower portions of the first outer casing piece 50 and the second outer casing piece 60, and are connected to the flow rate adjusting valve 74. The joints 93, 94 are attached to the upper portions of the first outer casing piece 50 and the second outer casing piece 60, and are connected to the flow path switching valve 81. By starting to supply water into the electrolyzed water generating apparatus 1, the entire flow of water is generated from the lower portion of the anode chamber 40A and the cathode chamber 40B toward the upper portion.

The hydrogen gas generated in the cathode chamber 40B becomes minute bubbles and moves above the cathode chamber 40B. In the present embodiment, since the moving direction of the hydrogen gas coincides with the entire flow direction of the water, the hydrogen molecules are easily dissolved in the water to increase the hydrogen dissolution concentration.

Fig. 3 is a perspective view of the first outer casing piece 50 and the second outer casing piece 60 as viewed from the inner surface side toward the electrolysis chamber 40 side. Fig. 4(a) is a front view of the first outer casing piece 50 as seen from the inner surface side, and Fig. 4(b) is a front view of the second outer casing piece 60 as seen from the inner surface side. Fig. 5 is an assembled perspective view of the electrolytic cell 4 including the A-A section and the B-B section of Fig. 4. In addition, Fig. 6 is a cross-sectional view of the electrolytic cell 4 in the same cross section as Fig. 5.

Engagement faces 51, 61 for fixingly joining the first outer casing piece 50 and the second outer casing piece 60 are formed at outer edge portions of the inner surfaces of the first outer casing piece 50 and the second outer casing piece 60. Electrolytic portions 52 and 62 are provided in the thickness direction of the first outer shell piece 50 and the second outer shell piece 60 from the joint faces 51 and 61 through the inner wall through the inner wall of the joint faces 51 and 61. The electrolysis portion 52 constitutes an anode chamber 40A, and the electrolysis portion 62 constitutes a cathode chamber 40B.

A plurality of first convex portions 53 are disposed on the inner surface of the first outer casing piece 50. In the present embodiment, the first convex portion 53 includes protrusions 53P that are discretely disposed on the main portion 52A of the electrolysis portion 52. The main portion 52A is a region that occupies most of the electrolysis portion 52 on the inner side of the edge portion 41e of the anode power supply body 41 and the edge portion 42e of the cathode power supply body 42 (hereinafter, the main portion 62A of the electrolysis portion 62 is also the same). Each of the first convex portions 53 is arranged in a matrix (matrix shape) in the longitudinal direction V and the lateral direction H perpendicular to the longitudinal direction V. The arrangement of the protrusions refers to an arrangement in which m protrusions are arranged in the vertical direction V and n protrusions are arranged in the lateral direction H (for example, an arrangement of m rows × n columns of matrix) (m, n is 2 or more) The integer is the same as the following).

On the other hand, a plurality of second convex portions 63 are disposed on the inner surface of the second outer casing sheet 60. In the present embodiment, the second convex portion 63 includes protrusions 63P that are discretely disposed on the main portion 62A of the electrolysis portion 62. Each of the second convex portions 63 is arranged in a matrix in the longitudinal direction V and the lateral direction H.

Each of the first convex portions 53 abuts on the anode power supply body 41 in the anode chamber 40A, and presses the anode power supply body 41 toward the second outer casing sheet 60 side. On the other hand, each of the second convex portions 63 abuts on the cathode power supply body 42 in the cathode chamber 40B, and presses the cathode power supply body 42 toward the first outer casing sheet 50 side. Therefore, the laminate 45 is sandwiched by the respective first convex portions 53 and the respective second convex portions 63 from both surfaces thereof.

The first convex portion 53 includes a first protrusion 56 that abuts against the edge portion 41e (see FIGS. 2 and 6) of the anode power feeding body 41. The first protrusions 56 are provided in the periphery of the protrusions of the first convex portion 53 that are discretely disposed on the main portion of the electrolysis portion 52. Thereby, the edge portion 41e of the anode power supply body 41 is pressed toward the diaphragm 43 by the first projection 56, whereby the contact pressure between the edge portion 41e of the anode power supply body 41 and the diaphragm 43 is increased, and the contact resistance therebetween is lowered.

On the other hand, the second convex portion 63 includes a second protrusion 66 that abuts against the edge portion 42e (see FIGS. 2 and 6) of the cathode power supply body 42. The second protrusions 66 are provided in the periphery of the protrusions of the second convex portion 63 that are discretely disposed on the main portion of the electrolysis portion 62. Thereby, the edge portion 42e of the cathode power supply body 42 is pressed toward the diaphragm 43 by the second protrusion 66, whereby the contact pressure between the edge portion 42e of the cathode power supply body 42 and the diaphragm 43 is increased, and the contact resistance therebetween is lowered.

Therefore, the electrolysis current flowing through the edge portion 41e of the anode power supply body 41 and the edge portion 42e of the cathode power supply body 42 is increased, and electrolysis at each of the edge portions 41e and 42e can be promoted. Therefore, the hydrogen dissolution concentration of the electrolytic hydrogen water generated in the cathode chamber 40B can be easily increased.

In the present embodiment, a plurality of first protrusions 56 are provided along the edge portion 41e of the anode power supply body 41. Also, a plurality of second protrusions 66 are provided along the edge portion 42e of the cathode power supply body 42.

As shown in FIGS. 5 and 6, when the first outer casing piece 50 and the second outer casing piece 60 are fixedly joined, the sealing member 46 is disposed outside the first projection 56 and the second projection 66. Water may be supplied to the inner side of the sealing member 46, that is, the edge portion 41e of the anode power supply body 41 and the edge portion 42e of the cathode power supply body 42.

As shown in FIGS. 3 to 6, each of the second projections 66 is disposed between the adjacent first projections 56 at intervals. In other words, each of the first protrusions 56 is disposed between the adjacent second protrusions 66 at intervals. Thereby, the edge portion 41e of the anode power supply body 41 and the edge portion 42e of the cathode power supply body 42 are alternately pressed and supported by the first protrusion 56 and the second protrusion 66 from the first outer shell piece 50 side and the second outer shell piece 60 side. Further, the hydrogen gas generated in the edge portion 42e is easily dissolved in the water flowing between the adjacent second protrusions 66, so that the hydrogen dissolution concentration is further increased.

As shown in Fig. 6, preferably, the heights of the first protrusions 56 and the second protrusions 66 are set to the extent that the edge portion 41e of the anode power supply body 41 and the edge portion 42e of the cathode power supply body 42 can be corrected to have a waveform. Since the edge portion 41e of the anode power supply body 41 of this waveform and the edge portion 42e of the cathode power supply body 42 have a large bending rigidity, even if the laminate 45 is subjected to a large stress due to a pressure difference in the electrolytic chamber 40, It is also possible to suppress the deformation thereof and suppress the damage of the diaphragm 43.

As shown in FIGS. 3 to 6, the first projection 56 includes a first elongated projection 57 that is long in the longitudinal direction V of the flow of water in the anode chamber 40A. The first vertical projection 57 abuts against the lateral edge portion 41h of the anode power supply body 41 in the lateral direction H. The lateral edge portion 41h is pressed toward the diaphragm 43 by the first longitudinal projection 57, thereby increasing the contact pressure with the diaphragm 43. In addition, the lateral edge portion 41h of the anode power supply body 41 is, for example, from the edge to the inner side of the lateral direction H of the anode power supply body 41, and is a region of 2% or less of the length H of the anode power supply body 41 (hereinafter, regarding the cathode power supply body) The lateral edge portion 42h of 42 is also the same).

The second projection 66 includes a second elongated projection 67 that is elongated in a longitudinal direction V along the flow of water within the cathode chamber 40B. In the side view of the electrolytic cell 4 viewed from the lateral direction H, each of the second longitudinal projections 67 is provided between the adjacent first longitudinal projections 57 at intervals. The second vertical projection 67 abuts against the lateral edge portion 42h of the cathode power supply body 42 in the lateral direction H. The lateral edge portion 42h is pressed toward the diaphragm 43 by the second longitudinal projection 67, thereby increasing the contact pressure with the diaphragm 43. Further, each of the second longitudinal projections 67 may be alternately disposed in the longitudinal direction V with the first longitudinal projections 57, or may be disposed in the lateral direction H when the first outer casing sheet 50 and the second outer casing sheet 60 are fixedly joined. The adjacent first longitudinal projections 57 are staggered.

The top portion 53a of the first convex portion 53 is configured to include a convex curved surface 53b having a center on the side of the first outer casing piece 50. The convex curved surface 53b includes a convex curved surface 57b formed on the top portion 57a of the first elongated projection 57 shown in Fig. 6. The convex curved surface 53b may be a quadric surface such as a part of the side surface of the cylinder, or may be a cubic curved surface such as a part of the surface of the sphere. Since the top portion 53a is configured as the convex curved surface 53b, the laminate 45 is curved with a slow curvature, so that the stress concentration to the diaphragm 43 is slow, and damage of the diaphragm 43 can be suppressed.

The top portion 63a of the second convex portion 63 is configured to include a convex curved surface 63b having a center on the side of the second outer casing sheet 60. The convex curved surface 63b includes a convex curved surface 67b formed on the top portion 67a of the second longitudinal projection 67 shown in Fig. 6. The convex curved surface 63b is also the same as the above-described convex curved surface 53b.

In the present embodiment, when the first outer casing piece 50 and the second outer casing piece 60 are fixedly joined, the second convex portion 63 is disposed between the first convex portions 53, 53 adjacent to each other in the longitudinal direction V. Along with this, the second convex portion 63 is disposed to be one row smaller than the first convex portion 53. In addition, the second convex portion 63 is disposed between the first convex portions 53, 53 adjacent to each other in the lateral direction H.

The second convex portions 63 are discretely and uniformly distributed in the longitudinal direction V and the lateral direction H in the cathode chamber 40B by the relative arrangement of the first convex portions 53 and the second convex portions 63. Thereby, water having a large flow velocity flows between the second convex portions 63 distributed in the longitudinal direction V and the lateral direction H in the cathode chamber 40B, thereby supplying sufficient water to the surface of the cathode power supply body 42. Therefore, even if a large amount of hydrogen gas is generated on the surface of the cathode power supply body 42 by, for example, increasing the electrolysis current supplied to each of the power supply bodies 41 and 42, the hydrogen dissolution concentration of the electrolytic hydrogen water can be suppressed locally. The saturation value is approached, thereby increasing the hydrogen dissolution concentration of the cathode chamber 40B as a whole. Further, even when, for example, the flow rate of the water supplied to the cathode chamber 40B is small, it is possible to suppress the hydrogen dissolution concentration of the electrolytic hydrogen water from locally approaching the saturation value, thereby increasing the hydrogen dissolution concentration of the entire cathode chamber 40B.

On the other hand, in the anode chamber 40A, each of the first convex portions 53 is discretely and equally distributed in the longitudinal direction V and the lateral direction H, and flows between the first convex portions 53 distributed in the longitudinal direction V and the lateral direction H in the anode chamber 40A. The water having a large flow rate supplies sufficient water to the surface of the anode power supply body 41. Therefore, similarly to the above-described cathode chamber 40B, the hydrogen dissolution concentration of the entire anode chamber 40A is improved. Thereby, the oxygen generated in the anode chamber 40A can be easily dissolved in the water in the anode chamber 40A and discharged.

The first convex portion 53 and the second convex portion 63 are formed into a vertically long shape that is long in the longitudinal direction V. By using the first convex portion 53 and the second convex portion 63 of such an elongated shape, the water in the anode chamber 40A and the cathode chamber 40B is rectified so as not to hinder the entire water flow in the longitudinal direction V, and can be sturdy in a wide area. The laminate 45 is supported. Therefore, the contact resistance between the respective power supply bodies 41 and 42 and the plating layer 43a of the separator 43 can be reduced, and the water in the electrolytic chamber 40 can be efficiently electrolyzed. In the present embodiment, the first convex portion 53 having a vertically long shape is an elliptical columnar protrusion, but may be a long columnar or rectangular parallelepiped protrusion.

Each of the first convex portions 53 abuts on the anode power supply body 41 at the top portion 53a. The top portion 53a protrudes, for example, at the same height as the joint surface 51. Thereby, the anode power feeding body 41 is pressed toward the second outer casing piece 60 side at a portion abutting on the top portion 53a to protrude. On the other hand, each of the second convex portions 63 abuts on the cathode power supply body 42 at the top portion 63a. Thereby, the cathode power supply body 42 is pressed toward the first outer casing piece 50 side at a portion abutting on the top portion 63a to protrude.

In the present invention, since the second convex portion 63 is disposed between the first convex portions 53, 53 adjacent in the longitudinal direction V, the laminated body 45 is corrected to have a waveform in a cross section in the longitudinal direction V. On the other hand, since the second convex portion 63 is disposed between the first convex portions 53, 53 adjacent to each other in the lateral direction H, the laminated body 45 is also corrected to a waveform in the cross section along the lateral direction H. . Since the laminate 45 of such a waveform has a large bending rigidity, even if the laminate 45 is subjected to a large stress due to a pressure difference in the electrolytic chamber 40, deformation thereof can be suppressed, and damage of the separator 43 can be suppressed.

As shown in FIGS. 3 and 4, it is preferable that the inner surface of the first outer shell piece 50 facing the electrolysis chamber 40 side is interposed between the laminate 45 (see FIG. 2) and the second outer casing. A plurality of first small projections 54 are disposed at positions opposite to the second convex portions 63 (protrusions 63P) of the sheet 60. Each of the first small projections 54 blocks a portion of the water flowing in the longitudinal direction V between the first convex portions 53, 53 adjacent in the lateral direction H, and guides it to both ends of the lateral direction H of the first small projections 54, That is, between the first convex portions 53, 53 adjacent in the longitudinal direction V. Thereby, the water in the anode chamber 40A is partially stirred at the periphery of the first small protrusion 54. Therefore, by fusing the entire water flow in the longitudinal direction V caused by the first convex portion 53 and the local water flow caused by the first small projections 54, the flow of water supplied to the surface of the anode power supply body 41 is further uniformized, and hydrogen can be improved. Dissolved concentration.

Preferably, the first small protrusions 54 are formed into a horizontally long shape that is long in the lateral direction H. Such a first small protrusion 54 has a higher effect of guiding water between the first convex portions 53, 53 adjacent in the longitudinal direction V, and the flow of water supplied to the surface of the anode power supply body 41 is further uniformed, Thereby, the hydrogen dissolution concentration can be increased. In the present embodiment, the first convex portion 53 having a horizontally long shape is an elliptical columnar projection, but may be a long cylindrical shape or a rectangular parallelepiped projection.

Since the height of the first small protrusions 54 is smaller than that of the first convex portions 53, it does not abut against the anode power supply body 41. Therefore, a flow path is formed between the first small protrusions 54 and the anode power supply body 41, and the flow of water supplied to the surface of the anode power supply body 41 is further uniformized.

On the other hand, preferably, the inner surface of the second outer shell piece 60 facing the electrolysis chamber 40 side is separated from the first convex portion of the first outer shell piece 50 via the laminate 45 (refer to FIG. 2). A plurality of second small protrusions 64 are disposed at positions opposite to each other at 53 (protrusions 53P). Since the shape and function of the second small projection 64 are the same as those of the first small projection 54, the description thereof will be omitted.

In the present invention, since the second small projection 64 provided in the vicinity of the second projection 66 guides the water in the cathode chamber 40B toward the lateral edge portion 42h of the cathode power supply body 42, it is also possible to the lateral edge portion 42h of the cathode power supply body 42. The surface is fully supplied with water. Therefore, hydrogen gas generated by the electrolysis promoting action of the edge portion 42e by the first protrusions 56 and the second protrusions 66 described above is easily dissolved in water, and the hydrogen dissolution concentration is easily increased.

As shown in FIGS. 3 and 6, it is preferable that the first small projections 54 are formed with grooves 55 penetrating the first small projections 54 in the longitudinal direction V. The number, width and depth of the grooves 55 with respect to one first small projection 54 can be appropriately set. For example, in the present embodiment, one groove 55 is provided at the central portion of the lateral direction H of the first small protrusion 54. In addition, the depth of the groove 55 is the same as the height of the first small protrusion 54. The groove 55 guides a portion of the water flowing between the first convex portions 53, 53 adjacent in the lateral direction H in the longitudinal direction V and passes it through the first small protrusions 54. Through the groove 55, the flow of water supplied to the surface of the anode power supply body 41 is further uniformized.

Also, it is preferable that the second small projection 64 is formed with a groove 65 penetrating the second small projection 64 in the longitudinal direction V. The number of the grooves 65 and the like are the same as those of the above-described grooves 55. The groove 65 guides a portion of the water flowing between the second convex portions 63, 63 adjacent in the lateral direction H in the longitudinal direction V and passes it through the second small protrusions 64. The flow of water supplied to the surface of the cathode power supply body 42 is further uniformized by the grooves 65.

Further, there is a possibility that the flow of water in the anode chamber 40A and the cathode chamber 40B is hindered by the first small projections 54 and the second small projections 64 described above. However, in the present embodiment, the height of the first small protrusions 54 is smaller than the height of the first convex portions 53, and the first small protrusions 54 are not in contact with the anode power supply body 41. Therefore, a flow path is formed between the first small protrusions 54 and the anode power supply body 41, and the possibility that the first small protrusions 54 block the flow of water in the anode chamber 40A is limited. Also, the possibility of obstructing the flow of water in the cathode chamber 40B due to the second small protrusions 64 is limited.

As shown in FIGS. 3 and 4, a first water dividing path 58D is formed at a lower portion of the inner surface of the first outer casing piece 50. The first water dividing passage 58D extends in the lateral direction H of the first outer casing piece 50 and communicates with the electrolysis portion 52. The water that has flowed in from the joint 91 flows into the electrolysis unit 52 through the first water dividing passage 58D, and flows upward through the gap of the first convex portion 53 or the like. Similarly, a second water dividing path 68D is formed at a lower portion of the inner surface of the second outer casing piece 60. The second water dividing passage 68D extends in the lateral direction H of the second outer casing piece 60 and communicates with the electrolysis portion 62. The water that has flowed in from the joint 92 flows into the electrolysis unit 62 through the second water dividing passage 68D, and flows upward through the gap of the second convex portion 63 or the like.

On the other hand, a first water collecting passage 58C is formed in an upper portion of the inner surface of the first outer shell piece 50. The first water collection path 58C extends in the lateral direction H of the first outer casing piece 50 and communicates with the electrolysis portion 52. The water that has moved to the upper side of the electrolysis unit 52 is collected by the first water collection path 58C, and flows out from the joint 93 to the outside of the electrolytic cell 4. Similarly, a second water collection path 68C is formed on the upper portion of the inner surface of the second outer casing piece 60. The second water collecting path 68C extends in the lateral direction H of the second outer casing piece 60 and communicates with the electrolysis portion 62. The water moved to the upper side of the electrolysis section 62 is collected by the second water collection path 68C, and flows out from the joint 94 to the outside of the electrolytic cell 4.

When the joint surface 51 is used as a reference, the depth of the electrolysis portion 52 is smaller than the first water dividing passage 58D and the first water collecting passage 58C. The electrolysis unit 52 increases the speed of the water flowing through the electrolysis unit 52, thereby easily dissolving oxygen. Further, a slope 59 is formed in the step portion between the electrolysis portion 52 and the first water dividing passage 58D and the first water collecting passage 58C. The slope 59 smoothes the flow of water in the anode chamber 40A and suppresses a decrease in the speed of the water flowing in the electrolysis portion 52.

Similarly, the depth of the electrolysis portion 62 is smaller than the second water dividing passage 68D and the second water collecting passage 68C based on the joint surface 61. The electrolysis unit 62 increases the speed of the water flowing through the electrolysis unit 62, thereby easily dissolving hydrogen gas. Further, a slope 69 is formed in the step portion between the electrolysis portion 62 and the second water dividing passage 68D and the second water collecting passage 68C. The inclined surface 69 smoothes the flow of water in the cathode chamber 40B and suppresses a decrease in the speed of the water flowing in the electrolytic portion 62.

Fig. 7 shows a first outer casing piece 50A as a modification of the first outer casing piece 50. On the other hand, Fig. 8 shows a second outer casing piece 60A as a modification of the second outer casing piece 60.

Thereby, the longitudinal edge portion 41v of the anode power supply body 41 is supported by the first laterally long projections 57A. Therefore, even when a large pressure difference is generated between the anode chamber 40A and the cathode chamber 40B, deformation of the laminate 45 can be suppressed, and damage of the diaphragm 43 can be suppressed. In addition, the longitudinal edge portion 41v of the anode power supply body 41 is, for example, an area from the edge of the longitudinal direction V of the anode power supply body 41 to the inner side, which is 2% or less of the longitudinal V length of the anode power supply body 41 (hereinafter, regarding the cathode power supply body) The longitudinal edge portion 42v of 42 is also the same).

Also, as shown in Fig. 8, the second projection 66 includes a second laterally elongated projection 67A that is long in the lateral direction H.

Thereby, the longitudinal edge portion 42v of the cathode power supply body 42 is supported by the second horizontally long projection 67A. Therefore, even when a large pressure difference is generated between the anode chamber 40A and the cathode chamber 40B, deformation of the laminate 45 can be suppressed, and damage of the diaphragm 43 can be suppressed. Further, each of the second laterally elongated projections 67A may be alternately disposed in the lateral direction with the first laterally elongated projections 57A, or may be disposed in the longitudinal direction V when the first outer casing sheets 50 and the second outer casing sheets 60 are fixedly joined. The adjacent first horizontally long projections 57A are staggered.

For the first outer casing piece 50B and the second outer casing piece 60B, a part of the first convex portion 53 and the second convex portion 63 may be replaced with the first convex portion 53B and the second convex portion 63B. For example, a first convex portion 53 discretely disposed on a main portion of the electrolytic portion 52 and a first groove portion 54B extending continuously in the longitudinal direction V may be mixed and mixed in the first outer shell piece 50B. Similarly, a second convex portion 63 discretely disposed on the main portion of the electrolytic portion 62 and a second groove portion 64B extending continuously in the longitudinal direction V may be mixed and mixed in the second outer casing piece 60B.

In this case, deformation of the laminate 45 can also be suppressed, and damage of the separator 43 can be suppressed. Further, preferably, the heights of the first protrusions 56 and the second protrusions 66 constructed by such convex portions are set so as not to be caused by the contact pressure between the diaphragm 43 and the anode power supply body 41 and the cathode power supply body 42.
