NOVELTY - An electrode comprises a gas diffusion layer (208) contacting with a separator (210) having a channel and a catalyst layer (203, 205) interposed between the gas diffusion layer and an electrolyte membrane (201). The catalyst layer has two portions (21, 22) 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.    USE - Electrode for a fuel cell.    ADVANTAGE - The electrode can control hydrophilicity of the catalyst layer differently according to locations, and keep an amount of moisture in an electrode in a suitable way and prevent shortage of moisture near a channel, thus improving the performance of the cell. The electrode can provide fuel cell operating in a low humidity condition with humidity of 0-70%.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a method of preparing an electrode for a fuel cell, comprising preparing a first catalyst layer forming ink including a metal catalyst or a metal catalyst on a carbon-based support, a polymer ionomer and a solvent, and a second catalyst layer forming ink including a metal catalyst or a metal catalyst on a carbon-based support, a polymer ionomer, a hydrophilicity enhancer and a solvent, respectively; and spraying the two catalyst layer forming inks to an electrolyte membrane or a gas diffusion layer by using ink jet spraying such that the first catalyst layer forming ink is sprayed to a portion that does not face a channel and the second catalyst layer forming ink is sprayed to a portion that faces a channel, thus forming a catalyst layer;    (2) a membrane electrode assembly for a fuel cell, comprising an electrolyte membrane, and an anode and a cathode; and    (3) a fuel cell comprising a stack having membrane electrode assemblies, and a separator; a fuel providing unit; and an oxidant providing unit.    Each anode and cathode has a catalyst layer and a gas diffusion layer. The anode and the cathode are the electrode for a fuel cell.
