摘要： A fuel cell includes a membrane electrode assembly and first and second metal separators for sandwiching the membrane electrode assembly. In the membrane electrode assembly, a surface area of a gas diffusion layer is larger than a surface area of a gas diffusion layer. A seal member is provided at a position corresponding to an outer marginal region of the gas diffusion layer. The seal member includes a main seal inserted between a solid polymer electrolyte membrane and the first metal separator, and an a flow field wall inserted between the gas diffusion layer and the first metal separator for defining a part of an oxygen-containing gas flow field.

摘要： A fuel cell is formed by sandwiching a membrane electrode assembly between a first separator and a second separator. A fuel gas flow field is formed in the second separator. An inlet buffer is connected to the inlet of the fuel gas flow field, and an outlet buffer is connected to an outlet of the fuel gas flow field. The inlet buffer is deeper than the outlet buffer. Therefore, the pressure loss in the inlet buffer is smaller than the pressure loss in the outlet buffer.

摘要： A fuel cell stack comprising a second metal separator set to have an external dimension larger than a first metal separator, wherein the second metal separator comprises, formed integrally, a first seal member in contact with the peripheral edge of a first electrolyte membrane/electrode structure, a second seal member in contact with the peripheral edge of the first metal separator, and a third seal member in contact with the peripheral edge of an adjoining fourth metal separator. Since the first seal member, the second seal member and the third seal member are integrally formed on one surface of the second separator or one surface of the first separator, a seal-forming step can be carried out at one effort, simply and economically. In addition, use of a triple seal structure containing the first through the third seal members can favorably improve the sealing feature of reaction gas and minimize reaction gas leakage.

摘要： A fuel cell stack includes a stack body formed by stacking a plurality of power generation cells in a stacking direction. At opposite ends of the stack body in the stacking direction, end power generation cells are provided. An end coolant flow field is formed on a separator of the end power generation cell. The flow rate of the coolant in the end coolant flow field is smaller than the flow rate of the coolant in a coolant flow field in each of the power generation cells. Specifically, the number of flow grooves of the end coolant flow field is smaller than the number of flow grooves of the coolant flow field.

摘要： An oxygen-containing gas flow field is formed on a surface of a first metal separator. The oxygen-containing gas flow field is connected between an oxygen-containing gas supply passage and an oxygen-containing gas discharge passage. The oxygen-containing gas flow field comprises oxygen-containing gas flow grooves, and ends of the oxygen-containing gas flow grooves are extended outwardly beyond ends of electrode catalyst layer of a membrane electrode assembly, and connected to an inlet buffer and an outlet buffer. When the purging process is performed at the time of stopping operation of the fuel cell, the purging air supplied to the oxygen-containing gas flow field discharges water retained in the electrode catalyst layers from the ends to the outlet buffer.
