TERMINAL PLATE FOR FUEL CELL, AND FUEL CELL

摘要

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.

1. A terminal plate for fuel cell, 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 gas flow hole that is formed to pass through the plate stacked body on an inner side of a stacked body outer periphery; a cooling water flow hole that is formed to pass through the plate stacked body on the inner side of the stacked body outer periphery such as not to interfere with the gas flow hole; a first gasket that is mounted to the second metal plate and is provided to surround at least the gas flow hole on the second metal plate-side; and a second gasket that is mounted to the second metal plate and is provided to surround a cooling water flow area which communicates with the cooling water flow hole, on the second metal plate-side, wherein 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 used for supply of a gas and the cooling water flow hole used for supply of cooling water toward the plate outer circumferential end of the first metal plate.
