20120021337 | FUEL CELL CATALYST WITH METAL OXIDE/PHOSPHATE SUPPORT STRUCTURE AND METHOD OF MANUFACTURING SAME - A fuel cell supported catalyst includes an underlying support structure having at least one of a metal oxide and a metal phosphate. Catalyst particles are arranged onto and in engagement with the support structure. An intermediate conductive, corrosion-resistant layer, such as boron-doped-diamond, is arranged onto and in engagement with the support structure to surround the catalyst particles. The supported catalyst is produced by depositing the intermediate layer onto the support structure after the catalyst particles have been deposited on the underlying support structure, in one example. In another example, voids are provided in the intermediate layer, which has been deposited onto the underlying support structure, to subsequently receive the catalyst particles. | 01-26-2012 |
