摘要： A power generation cell includes an anode side seal member and a cathode side seal member. The anode side seal member is provided outside an anode of a membrane electrode assembly, and directly contacts a solid polymer electrolyte membrane. The cathode side seal member is provided outside the membrane electrode assembly. A space is formed between the anode side seal member and the cathode side seal member. First ribs are formed integrally with the anode side seal member. The first ribs protrude toward the space. Further, second ribs are formed integrally with the cathode side seal member. The second ribs protrude toward the space. The first ribs and the second ribs are arranged alternately.

摘要： A power generation cell includes a membrane electrode assembly, with an anode side metal separator and a cathode side metal separator sandwiching the membrane electrode assembly. Flow field walls are provided within the coolant flow field for preventing coolant from flowing into an area corresponding to an oxygen-containing gas inlet buffer, while allowing the coolant to flow into an area corresponding to an oxygen-containing gas outlet buffer. Likewise, flow field walls contact each other for preventing the coolant from flowing into an area corresponding to a fuel gas inlet buffer, while allowing the fuel gas to flow into an area corresponding to a fuel gas outlet buffer.

摘要： A fuel cell includes a membrane electrode assembly and an anode side metal separator and a cathode side metal separator sandwiching the membrane electrode assembly. An oxygen-containing gas flows in an oxygen-containing gas flow field in a horizontal direction. A coolant flows in a coolant flow field in a vertical direction. The coolant flow field is connected to coolant supply passages and coolant discharge passages. The opening of one of the coolant supply passages and the opening of one of the coolant discharge passages are smaller than those of the other coolant supply passages and the other coolant discharge passages in cross section, respectively. Thus, the flow rate of the coolant supplied to an area near outlets of the oxygen-containing gas flow field and the fuel gas flow field become smaller than the flow rate of the coolant supplied to the other area.
