Abstract: A membrane electrode assembly for a fuel cell is provided that includes a membrane, electrodes on both sides of the membrane, respectively, and sub-gaskets bonded to the edges of the electrodes, respectively. In particular, the sub-gasket may be bonded to the membrane at a predetermined distance from the edge of the electrode.

Abstract: Disclosed herein is a method of fabricating a catalyzed porous electrode for fuel cell, which electrode can be fabricated in a simple and easy manner without forming a catalyst support layer of carbon particles, and has an excellent, stable catalytic efficiency. The method comprises treating an electrically conductive, porous carbon substrate with an oxidizing agent; making one face of the porous carbon substrate in contact with an electrodeposition solution As containing ions of a catalytic metal; applying a pulsed potential to the electrodeposition solution to deposit the catalytic metal on the porous substrate, thereby catalyzing the porous substrate; and heat-treating the catalyzed porous substrate.
