摘要:
A membrane-electrode assembly for a fuel cell of the present invention includes an anode and a cathode facing each other, and a polymer electrolyte membrane interposed therebetween. At least one of the anode and the cathode includes a catalyst layer and an electrode substrate. The catalyst layer includes a catalyst and a porous ionomer. The polymer electrolyte membrane contacts one side of the catalyst layer and the electrode substrate contacts the other side of the catalyst layer.
摘要:
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.
