Electrode for fuel cell, method of manufacturing same, and fuel cell with such 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 mum. The electrode catalyst layer has cracks whose area is less than 10% of a total area of the electrode catalyst layer.
