Abstract:
1. A polymer electrolyte fuel cell, comprising: a polymer electrolyte membrane; an electrode catalyst layer provided on one surface of the polymer electrolyte membrane; a separator having electrical conductivity, and shielding gas; and an electrode member interposed between the electrode catalyst layer and the separator and constituting an electrode together with the electrode catalyst layer, wherein the electrode member comprises: first contact portions in direct contact with the electrode catalyst layer; second contact portions in direct contact with the separator; and gas diffusion paths through which the gas flows, the electrode member is provided with a large number of pores formed therein, and constituted by a plate member having electrical conductivity and bent into a wave shape, and the electrode catalyst layer comprises: a catalyst component layer containing a catalyst component; a protection layer having electrical conductivity interposed between the catalyst component layer and the electrode member to prevent damage of the catalyst component layer; and a conductor provided on a surface of the protection layer and coming into contact with the first contact portions of the electrode member so as to electrically connect the protection layer to the electrode member.
