Abstract
The present invention relates to an electrode catalyst, a method for preparing the electrode catalyst, and a membrane electrode assembly and a fuel cell including the electrode catalyst. The electrode catalyst includes a carbon support and a platinum catalyst supported on the carbon support. A thermally responsive polymer is selectively bound to the carbon support. The electrode catalyst can ensure smooth discharge of water produced as a result of an electrochemical reaction, achieving improved electrical performance of the fuel cell.
