Catalyst for fuel cell electrode |
摘要 |
The durability of a PEM fuel cell is improved by replacing carbon catalyst support materials in the cathode (and optionally both electrodes) with a titanium oxide support. The electrode thus preferably contains noble metal containing catalyst particles carried on catalyst support particles of titanium oxide. The catalyst-bearing titanium oxide particles are mixed with electrically conductive material such as carbon particles. The combination of platinum particles deposited on titanium dioxide support particles and mixed with conductive carbon particles provides an electrode with good oxygen reduction capacity and corrosion resistance in an acid environment.
