A cathode for a fuel cell includes a gas diffusion layer contacting with a separator having a channel and a catalyst layer interposed between the gas diffusion layer and an electrolyte membrane. The catalyst layer of the cathode has two portions with different water-repelling properties, and a portion of the catalyst layer that does not face a channel has a higher water-repelling property than a portion that faces a channel. This cathode controls water-repelling property of the catalyst layer differently according to locations, so it is possible to keep an amount of moisture in an electrode in a suitable way and to restrain generation of flooding, thereby improving the performance of the cell.

An electrode for a fuel cell includes a gas diffusion layer contacting with a separator having a channel and a catalyst layer interposed between the gas diffusion layer and an electrolyte membrane. The catalyst layer of the electrode has two portions with different hydrophilicities. A portion of the catalyst layer that faces a channel has a higher hydrophilicity than a portion that does not face a channel. This electrode may control hydrophilicity of the catalyst layer differently according to locations, so it is possible to keep an amount of moisture in an electrode in a suitable way, thereby improving the performance of the cell.
