NOVELTY - The cathode for a fuel cell or a membrane electrode assembly, comprises a gas diffusion layer (208) contacting with a separator (210) having a channel and a catalyst layer interposed between the gas diffusion layer and an electrolyte membrane (201). The catalyst layer has two portions with different water-repelling properties, where a portion of the catalyst layer that does not face the channel has a higher water-repelling property than a portion (22) that faces the channel. The portions with different water-repelling properties have contact angles to water.    USE - The cathode is useful for fuel cell or a membrane electrode assembly (claimed).    ADVANTAGE - The cathode controls water-repelling property of the catalyst layer differently according to locations so that it maintains an amount of moisture in an electrode and restrains generation of flooding thus improving the performance of the cell.    DETAILED DESCRIPTION - The cathode for a fuel cell or a membrane electrode assembly, comprises a gas diffusion layer (208) contacting with a separator (210) having a channel and a catalyst layer interposed between the gas diffusion layer and an electrolyte membrane (201). The catalyst layer has two portions with different water-repelling properties, where a portion of the catalyst layer that does not face the channel has a higher water-repelling property than a portion (22) that faces the channel. The portions with different water-repelling properties have contact angles to water, where a difference of contact angles to water is 2 to 20 degrees . The portion of the catalyst layer, which faces the channel includes a metal catalyst or a metal catalyst on a carbon-based support, and a polymer ionomer. The portion of the catalyst layer, which does not face a channel and has higher water-repelling property than the portion facing a channel, includes a metal catalyst or a metal catalyst on a carbon-based support, a polymer ionomer, and a hydrophobic polymer-based water-repelling enhancer. A weight ratio of the metal catalyst to the hydrophobic polymer-based water-repelling enhancer is 1:0.02 to 0.40. INDEPENDENT CLAIMS are included for:    (1) a method of preparing a cathode for a fuel cell;    (2) a membrane electrode assembly; and    (3) a fuel cell.
