摘要:
The membrane-electrode assembly for a fuel cell includes an anode and a cathode facing each other and a polymer electrolyte membrane interposed therebetween. The cathode includes an electrode substrate and a catalyst layer disposed on the electrode substrate, and the catalyst layer has a mesopore volume ranging from 0.013 to 0.04 cm3/g. The membrane-electrode assembly has low mass resistance and contributes to the overall increased performance of the fuel cell by having optimal pore volumes (e.g., mesopore volume) in a cathode catalyst layer to provide ease of transfer and release of materials within the membrane-electrode assembly of the fuel cell.
