<p>The process is for the production of an electrode structure and its use in a fuel cell. A metal oxide (11) with a thickness bewteen 0.5 and 500 nm separates platinum catalysts (10) from polymer electrolyte (12). Proton feed occurs via the metal oxide. Electrons are fed to an outer circuit via the electrically conductive material (13). In the cathode case, protons are conducted from the polymer electrolyte through the metal oxide to the catalyst particles. In the anode case, protons are fed from the catalyst particles through the metal oxide to the polymer electrolyte. The foregoing electrode structure is suitable for the production of miniature fuel cells. These are suitable for the production of miniature fuel cells. These are suitable for portable computers, telephones and media players. Such an electrode structure is convenient for anodes in hydrogen-driven fuel cells, where a small quantity of catalyst is appropriate. With a plain electrode, improved mass transport of gases to catalyst particles can be achieved, as compared with a conventional porous electrode.</p> |
