[Also in Division H1] A catalyst for a fuel cell electrode contains one or more tellurides and/or selenides of Mo, Cr or W, and may additionally contain a molybdenum sulphide and/or tungsten sulphide, and an electrically conductive additive such as carbon or tungsten carbide. The electrodes may be made by pulverizing, pressing and subsequently sintering the raw materials after treatment with a thermoplastic synthetic substance such as polyethylene, polypropylene, polycarbonate or halogenated polyolefins. |
