Abstract

Disclosed herein are a membrane electrode assembly (MEA) for fuel cells, wherein the membrane electrode assembly has a porous membrane (a catalyst trapping layer) disposed at the opposite surface of a catalyst layer facing a polymer electrolyte membrane for preventing the loss of a catalyst, and a fuel cell including the same. The membrane electrode assembly has the effect of restraining the loss of the catalyst due to a liquid component, such as methanol, thereby improving the operating efficiency of the fuel cell. Especially, the membrane electrode assembly has the effect of minimizing the reduction in performance of the fuel cell due to the loss of the catalyst during the long-term operation.
