Abstract
A fuel cell according to the present disclosure includes a flat plate-shaped metal porous body having a framework of a three-dimensional network structure as a gas diffusion layer. The framework is made of metal or alloy. In the metal porous body, a ratio of an average pore diameter in a direction parallel to a gas flow direction to an average pore diameter in a direction perpendicular to the gas flow direction is greater than or equal to 1.4 and less than or equal to 2.5.
