MEMBER FOR POLYMER FUEL CELL, ITS MANUFACTURING METHOD, AND POLYMER FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a member for a fuel cell capable of preventing the leakage of fuel and an oxidant caused by cracks generated in an electrolyte membrane in the boundary between a seal part and a diffusion part, and to provide the polymer fuel cell.

SOLUTION: The constituting member for the polymer fuel cell is comprised of an insulating porous sheet 7 having a conductive part 10 whose circumference is an insulating part 11. The polymer fuel cell uses the constituting member for the fuel cell. The constituting member for the fuel cell is installed between a polymer electrolyte membrane and an electrode, the conductive part of the constituting member for the fuel cell is used as the diffusion layer part, and the insulating part is used as the seal part.
