まねくという問題点が考慮されていなかった。However, in a battery structure in which fuel gas and oxidant gas flow from the cell inlet to the outlet, the gas concentration decreases due to electrochemical reactions, and the gas temperature increases due to the heat generated.
A large output and temperature difference occurs between the outlets, resulting in a decrease in efficiency and reliability from a performance standpoint, and a decrease in reliability and life due to an increase in thermal stress and an increase in electrolyte loss from a lifespan standpoint. This issue was not taken into account.

下という問題があった。The above-mentioned conventional technology does not take into consideration the gas flow path structure regarding the non-uniform concentration of the fuel and oxidant gas flowing inside the cell, and the rise in gas temperature, and the large current density and temperature difference that occur between the inlet and outlet of one pond. There was a problem of a decrease in performance, reliability, and lifespan due to this.

池のセパレータ流路を提供することにある。The purpose of the present invention is to create a fuel cell with high performance, high reliability, and long life by making the concentration distribution of fuel gas and oxidizing gas flowing inside the cell uniform and also making the cell temperature distribution uniform. The object of the present invention is to provide a separator flow path.

に達成される。The above purpose is to construct a corrugated thin plate that combines the gas flow path formation and current collection means between the electrode and the separation plate that separates fuel gas and oxidant gas, and only has a convex portion where the corrugated plate and the electrode come into contact. This is accomplished by cutting multiple pieces in the direction of gas flow, or by briding cutting or cutting off at any width and depth using an end mill. Furthermore, the corrugated thin plate forms a flow path in which the electrode and the gas are in direct contact, and a flow path in which the gas does not come into direct contact, but the end of the corrugated plate on the inlet side closes the end of the flow path that is in direct contact with the electrode. On the outlet side, the above objective can be more effectively achieved by closing the end of the flow path that does not come into direct contact with the electrode.

象はガス利用率の高い燃料側でより有効に働く。By scraping off one convex part of the corrugated thin plate in the flow direction to a certain size and bringing the western side of the processed corrugated plate into contact with the electrode surface, a gap between the electrode and the side wall of the convex part of the corrugated plate is created. As many openings as the number of processed holes are formed. Therefore, the openings are in contact with the electrode surface, and the reactive gas flows directly above the electrode surface through the multiple openings, so that the reactive gas with a gas composition approximately equal to the inlet reactive gas concentration is distributed throughout the entire cell to the electrode surface. By flowing over the surface, the electrical output distribution can be made uniform and high output can be achieved. This phenomenon works more effectively on the fuel side with a high gas utilization rate.

って反応流路内へ強制的に流入することとなる。Further, the lifespan and reliability of a fuel cell are closely related to the cell temperature, and in particular, in order to suppress the amount of loss of electrolyte, it is required to lower the maximum temperature as much as possible. Through a simple process of adjusting the pitch, cutting depth, and cutting width of multiple openings, more supply gas with a lower temperature than the post-reaction process gas is supplied to areas where the battery temperature is likely to be high. This reduces the maximum temperature and the temperature difference. This simultaneously reduces thermal stress and improves reliability. In order to facilitate the adjustment of the flow rate distribution within the battery, of the two flow passages formed by the corrugated plate, the electrode surface and the reaction gas are in direct contact with each other. By blocking the inlet part, and since the other channel, which does not have direct gas contact with the electrode surface, serves as a reaction gas supply header, by blocking the outlet part, it is possible to prevent the reaction that has entered the supply header. Gas will be forced to flow into the reaction channel through the opening.
この結果、セル全域に開口部の異なる大きさ、ピッチ等

An arbitrary number of openings 3 having a width W and a depth h are provided throughout the corrugated thin plate 1 by scraping off its upper part using a grinder 10. In addition, regarding the machining of the convex portion 2, an arbitrary width W can be obtained by adjusting the cutting width and depth of the grinder and end mill.

Further, FIGS. 4 and 5 show sectional views taken along the lines IV-IV and V-■, respectively, at that time. The corrugated thin body 1 is formed such that the opening 3 faces the opposite side from the separator 4.

The liquid flows through a flow path 14 formed by the recess 8 and the side wall 11-a. Note that in the flow path 15 surrounded by the inner wall 11-b of the corrugated sheet 1, a flow path closing portion 1 is simultaneously formed by pressing the corrugated sheet.

The flow path 14 cannot flow out through the outlet portion 17 due to the flow path obstruction portion 12 formed in the same manner as the obstruction portion 13.
All the gas that has entered will flow out through the opening 3.

とができろ。Next, the present invention will be described in detail using enlarged sectional views of the vicinity of the electrodes when a battery is constructed, as shown in FIGS. 6 and 7. The reaction gas flowing through the flow path 14 flows through the opening 3 provided in the direction of flow. In order to flow the reaction gas through the opening 3 throughout the cell, the area of the opening 3 is considerably smaller than that of the flow path 14, and the cutting depth h is made as small as possible. The reactant gas is arranged to flow as close to the electrode surface 5 as possible. Therefore, the reactant gas concentration on the electrode surface becomes higher than the average concentration in the flow path and approaches the inlet gas composition, resulting in a shift in the electrical output of the entire cell. Furthermore, the current density tends to become more uniform. Furthermore, as shown in Figure 3, when the battery temperature in area A is higher than area B in the cell, it is necessary to lower the temperature of this temperature control part, but this high temperature area A has an opening. To shorten the pitch ■, or to increase the cutting width W so that the opening area in this area becomes larger.
By making the pattern different from that in region B, it becomes possible to control the flow rate distribution, and it becomes possible to flow more cooling gas in region A than in other regions. As a result, the temperature can be made uniform and the maximum temperature can be kept as low as possible.
