ABSTRACT:
The electrode for a fuel cell of the present invention includes a catalyst layer and an electrode substrate supporting the catalyst layer, where the electrode substrate includes a hydrophilic region and a hydrophobic region separated from each other. The hydrophilic region and the hydrophobic region that are separated from each other can easily release water produced at the cathode, and thereby prevent clogging of pores of the membrane by water, and smoothly diffuse the reactants resulting in obtaining a high current density.
