METHOD FOR PRODUCING CATALYST LAYERS FOR FUEL CELLS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18547040 titled 'METHOD FOR PRODUCING CATALYST LAYERS FOR FUEL CELLS
Simplified Explanation
The invention relates to a method for producing a catalyst material comprising catalytically active nanoparticles, particularly for electrodes with catalyst layers as catalysts for a fuel cell. The method involves providing a first starting material containing a first metal, providing a second starting material containing a second metal, mixing the two starting materials to form a reactant material, and thermally treating the reactant material to produce catalytically active nanoparticles with an alloy of the first and second metal.
