Manufacturing Method Of Electrode Catalyst Layer, Electrode Catalyst Layer, Membrane Electrode Assembly And Fuel Cell

摘要

The present invention provides an electrode catalyst layer and a manufacturing method thereof, wherein the electrode catalyst layer contains an oxide type of non-platinum catalyst as the catalyst and enables a fuel cell employing the electrode catalyst layer to achieve a high level of power generation performance, as well as an MEA and the fuel cell which employ the electrode catalyst layer. The manufacturing method of the electrode catalyst layer of the present invention includes preparing a“catalyst provided with electrical conductivity on the surface”. In addition, the manufacturing method may further include preparing a catalyst ink, in which the“catalyst provided with electrical conductivity on the surface”, carbon particles and a polymer electrolyte are dispersed in a solvent, and coating the catalyst ink to form the electrode catalyst layer.
