ELECTRODE CATALYST, METHOD FOR PREPARING SAME, AND MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL COMPRISING SAME

摘要

The present invention relates to an electrode catalyst, a method for preparing the same, and a membrane electrode assembly and a fuel cell comprising the same, wherein the electrode catalyst includes a carbon based carrier and a platinum based catalyst carried on the carbon based carrier, and the carbon based carrier is selectively bonded to a thermally reactive polymer. The electrode catalyst can smoothly discharge water generated as a result of electrochemical reaction, and thus improve the electrical performance of the fuel cell.
