DURABLE IONOMERIC POLYMER FOR PROTON EXCHANGE MEMBRANE AND MEMBRANE ELECTRODE ASSEMBLIES FOR ELECTROCHEMICAL FUEL CELL APPLICATIONS

摘要

The present invention provides a proton exchange membrane and a membrane electrode assembly for an electrochemical fuel cell. A catalytically active component is disposed within the membrane electrode assembly. The catalytically active component comprises particles of cobalt cations and boron stabilized silicon oxide. The present invention also provides for a process for increasing peroxide radical resistance in a membrane electrode that includes the introduction of the catalytically active component described into a membrane electrode assembly.
