Abstract: A fuel cell electrode with catalysts grown in situ on an ordered structure microporous layer and a method for preparing a membrane electrode assembly (MEA) are disclosed. The fuel cell electrode includes an electrode substrate layer, a hydrophobic layer, an ordered structure hydrophilic layer and catalysts. The hydrophobic layer is prepared on the electrode substrate layer. The ordered structure hydrophilic layer is prepared on the hydrophobic layer. The catalysts are uniformly distributed on the ordered structure hydrophilic layer.

Abstract: This invention discloses an electrocatalyst for membrane electrode assembly, and its preparation method, as well as a fuel cell membrane electrode assembly. An electrocatalyst for fuel cell application, it is featured that the electrocatalyst is prepared by supporting precious metal (10-60 wt %) on a composite carrier which is prepared by depositing water-containing substance (0.3-10 wt %) on carbon material; Using the catalyst invented by this invention as anode catalyst, an fuel cell membrane electrode assembly with excellent non-humidification performance can be prepared by normal procedures. No need to construct a water retention layer, no need to add water retention material in proton exchange membrane, it avoids the possible problems caused by adding water attention material into proton exchange membrane or inserting a water retention layer. The approach suggested by this invention is a simple and effective approach to realize non-humidification membrane electrode assembly.
