Improved Electrocatalyst for Hydrogen Peroxide Cathodes and Electroplating Process

摘要

The present invention is related to fuel cells and fuel cell cathodes, especially for fuel cells using hydrogen peroxide as oxidant. According to an embodiment of the invention these fuel cells use cathodes that employ ruthenium alloys RuMeIMeIIsuch as ruthenium-palladium-iridium alloys or quaternary ruthenium-rhenium alloys RuMeIMeIIRe such as ruthenium-palladium-iridium-rhenium alloys as electrocatalyst (206) for hydrogen peroxide fuel cells. Methods for the preparation of the electrocatalyst and cathode are also disclosed.
