Abstract
A fuel cell equipped with at least an air electrode side power collector layer, an air electrode catalyst layer, a polymer electrolyte membrane, a fuel electrode catalyst layer and a fuel electrode side power collector layer and provided with a porous body layer having a porous body at a liquid fuel side of the fuel electrode side power collector layer assumes a structure in which the porous body layer is provided with a gas flow velocity (superficial velocity in the layer) of 10 to 5000 cm/s at a differential pressure of 100 kPa. The porous body layer is a diffusion medium of a fuel into the fuel electrode catalyst layer and a discharge resistor of gases comprising carbon dioxide and steam which are electrode reaction products and a vapor of the liquid fuel in progress of electrode reaction. An interface of the gases and a gases layer are also provided.
