MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL AND FUEL CELL STACK INCLUDING SAME

摘要

A membrane-electrode assembly for a fuel cell that includes a polymer electrolyte membrane is disclosed. The membrane-electrode assembly for a fuel cell further includes an anode disposed on one side of the polymer electrolyte membrane and including an anode gas diffusion layer and a cathode disposed on the other side of the polymer electrolyte membrane and including a cathode gas diffusion layer. At least one of the anode gas diffusion layer and the cathode gas diffusion layer includes a water reservoir. The water reservoir includes a pore and a hydrophilic polymer inside the pore. A fuel cell stack including the membrane-electrode assembly is also disclosed.
