Patent ID: 8518600

Claim:
A gas passage forming member in a fuel cell, wherein the fuel cell comprises an electrode layer, a gas diffusion layer formed on a surface of the electrode layer, and a separator facing the gas diffusion layer, the fuel cell generating electric power through electrode reaction in the electrode layer, a gas passage being formed between the gas diffusion layer and the separator to supply fuel gas or oxidant gas to the electrode layer, wherein the gas passage forming member is configured by a metal lath formed by a thin metal plate, a plurality of ring portions each having a through hole having a prescribed form being formed in the gas passage forming member and arranged in a grid-like shape, the ring portions are connected together through linking plate portions, each of the linking plate portions being inclined with respect to a flow direction of the gas, each linking plate portion including a first inclined plate portion held in contact with a backside of the separator and a second inclined plate portion held in contact with a surface of the gas diffusion layer, and a first inclination angle, which is the angle between the first inclined plate portion and the separator, is set smaller than a second inclination angle, which is the angle between the second inclined plate portion and the gas diffusion layer.
