PEM HAVING IMPROVED INERTNESS AGAINST PEROXIDE RADICALS AND CORRESPONDING MEMBRANE ELECTRODE ASSEMBLIES |
摘要 |
A proton exchange membrane and a membrane electrode assembly for an electrochemical cell such as a fuel cell are provided. A catalytically active component is disposed within the membrane electrode assembly. The catalytically active component comprises particles containing a metal oxide such as silica, metal or metalloid ions such as ions that include boron, and a catalyst. A process for increasing peroxide radical resistance in a membrane electrode is also provided that includes the introduction of the catalytically active component described into a membrane electrode assembly. |
