COMPOSITE SEPARATOR LAMINAE FOR POLYMER ELECTROLYTE FUEL CELLS AND POLYMER ELECTROLYTE FUEL CELL USING IT

摘要

PROBLEM TO BE SOLVED: To provide a composite separator laminate for a polymer electrolyte fuel cell with high conductivity and high formability.

SOLUTION: The composite separator laminate for the polymer electrolyte fuel cell is prepared in such a way that an electron good-conductor portion containing conductive carbon and a resin portion enveloping the electron good-conductor portion are formed by using different compounds in a conductivity necessary portion and a conductivity unnecessary portion by injection molding, and a first groove and a second groove for passing gas or cooling water are formed on both surfaces of the electron good-conductor portion.
