Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A direct methanol fuel cell comprising a membrane electrode assembly (MEA), wherein the membrane electrode assembly comprises a polymer electrolyte membrane, a fuel electrode and an air electrode, wherein the fuel electrode comprises a catalyst layer, a gas diffusion layer, and a catalyst trapping layer disposed at the opposite surface of the catalyst layer facing the polymer electrolyte membrane for preventing the loss of a catalyst, wherein the cat…
