Abstract
A fuel cell for generating electricity by reaction of reacting gases through a catalyst, which comprises a pair of electrodes each having a gas passage and being made from a porous substrate, an electrolyte-retaining matrix provided between the electrodes, and a pair of separator plates for partitioning the cells at the outer ends, one electrode in which a gas is formed by reaction of the reacting gases, among the pair of electrodes, having a catalyst layer and an independent gas inflow passage and an independent gas outflow passage as the gas passage and the reacting gas supplied from the gas inflow passage being passed through the electrode and the catalyst layer to the gas outflow passage as accompanied with the gas formed by the reaction of the reacting gas through the catalyst layer has a good diffusion of a reacting substance through the electrode and an improved electrode performance.
