SOLID POLYMER FUEL CELL AND SEPARATOR FOR SOLID POLYMER FUEL CELL

摘要

Disclosed is a separator for a solid polymer fuel cell, which comprises a flat plate and a corrugated plate that is arranged on the flat plate. The recessed portions of one of the two surfaces of the corrugated plate serve as gas channels, said surface not facing the flat plate. Since one of the two surfaces of the separator for a solid polymer fuel cell, which is in contact with the adjacent cell, is flat, a certain contact area can be always obtained between the adjacent cells. Consequently, the contact resistance between adjacent cells can be decreased, and a fuel cell stack having high output can be obtained.
