AIR-COOLED METAL SEPARATOR FOR FUEL CELL AND FUEL CELL STACK USING SAME

摘要

Disclosed herein is an air-cooled metal separator that does not need cooling water. The air-cooled metal separator includes a channel section formed in the middle of a metal plate, the channel section including a reaction gas channel depressed into a front surface of the metal plate to protrude from a rear surface thereof and an air channel defined between the reaction gas channels protruding from the rear surface of the metal plate; a first gasket continuously formed along a rim of a front surface of the channel section; and a second gasket discontinuously formed along a rim of a rear surface of the channel section to allow a discontinuous portion of the second gasket to provide a flow passage of air.
