POLYMER ELECTROLYTE FUEL CELL

摘要

A polymer electrolyte fuel cell comprises a separator including a gas channel through which oxidizing gas or fuel gas is supplied to a cell electrode. The separator consists of a metal plate, conductive film formed on the surface of the metal plate, and a diffused conductor layer between the metal plate and the conductive film. The fuel cell provides stable output for a long period while preventing the metal plate from corrosion or dissolution.
