There is provided a terminal plate comprising a plate stacked body including a first metal plate that is electrically conductive and has a current collecting terminal for power collection, and second metal plates that have higher corrosion resistance than the first metal plate and are placed across the first metal plate. A first gasket is mounted to the second metal plate and is provided to surround at least a gas flow hole used for supply of a gas on the second metal plate-side. A second gasket is mounted to the second metal plate and is provided to surround a cooling water flow area which communicates with a cooling water flow hole used for supply of cooling water on the second metal plate-side. The current collecting terminal is protruded from a plate outer circumferential end of the first metal plate in a direction from one flow hole of the gas flow hole and the cooling water flow hole toward the plate outer circumferential end of the first metal plate. This configuration enables the current collecting terminal to be cooled down from the second metal plate-side via the first metal plate.
