A fuel cell according to the present invention includes a power generation cell. The power generation cell is formed by sandwiching a membrane electrode assembly between a first metal separator and a second metal separator. An oxygen-containing gas flow field is formed on one surface of the first metal separator, and a coolant flow field is formed on the other surface of the first metal separator. The first metal separator includes a corrugated metal plate. A resin frame member is provided on one surface of the metal plate, and a rubber seal is provided on the other surface of the metal plate. An oxygen-containing gas supply passage, an oxygen-containing gas discharge passage, a coolant supply passage, a coolant discharge passage, a fuel gas supply passage, and a fuel gas discharge passage extend through the metal plate, the resin frame member, and the rubber seal.
A fuel cell formed by sandwiching an electrolyte electrode assembly between a first metal separator and a second metal separator, the electrolyte electrode assembly including a pair of electrodes, and an electrolyte interposed between the electrodes, wherein
