摘要： A fuel cell has a unit cell whose output is increased. A unit cell of a fuel cell includes a cathode electrode having a gas diffusion layer and an electrode catalyst layer. The electrode catalyst layer is made of carbon black carrying a PtnullMn-based alloy such as a PtnullMn alloy on its particle surface. For operating the fuel cell which includes the cathode electrode, it is preferable to make the pressure of an oxygen-containing gas supplied to the cathode electrode higher than the pressure of an hydrogen-containing gas supplied to an anode electrode to make the pressure at the cathode electrode higher than the pressure at the anode electrode.

摘要： A fuel cell provides a high output at a high current density. The fuel cell has an anode electrode and a cathode electrode comprising a gas diffusion layer, a water-repellent layer disposed on the gas diffusion layer and containing a carbon material and polytetrafluoroethylene, and an electrode catalyst layer disposed on the water-repellent layer and containing a carbon material carrying a catalyst. The electrode catalyst layer has maximum and minimum thicknesses that differ from each other by less than 30 nullm. The electrode catalyst layer has cracks whose area is less than 10% of a total area of the electrode catalyst layer.
