Abstract
Official abstract text for this publication.
A fuel cell or an electrolyser includes at least one electrode and at least one polymer electrolyte membrane. The electrode includes a catalyst system comprising a carrier metal oxide and a catalyst material. The catalyst material is formed by an electrically conductive metal phosphate in the form of a metaphosphate of the general chemical formula Me z n+2 (P n O 3n+1 ) z , where Me=metal, z=valency of the metal Me, and n is within the range of 1 to 10.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of constructing a fuel cell or an electrolyser comprising: providing a cathode comprising a catalyst system comprising a carrier metal oxide and a catalyst material, the providing of the cathode including mixing the carrier metal oxide and the catalyst material together to form a powder mixture in which an electrically conductive metal phosphate is adsorbed as the catalyst material on a surface of the carrier metal oxide, and depositing the mixed carrier metal oxide and catalyst material on a carrier plate, the electrically conductive metal phosphate being in the form of a metaphosphate of the general chemical formula Me z n+2 (P n O 3n+1 ) z , where Me=a metal, z=a valency of the metal Me, and n is within a range of 1 to 10; and arranging a polymer electrolyte membrane adjacent to the cathode; and after the mixing of the carrier metal oxide and the catalyst material together to form the powder mixture, applying a dopant by means of a sputtering process to the powder mixture. 2. The method as recited in claim 1 wherein a ratio of the carrier metal oxide and the catalyst material mixed together includes 80 to 90 wt % of the carrier metal oxide and 10 to 20 wt % of the catalyst material. 3. The method as recited in claim 1 , wherein the dopant is platinum.
