1,157,124. Fuel cell electrodes. GENERAL ELECTRIC CO. 30 Sept., 1966 [1 Oct., 1965], No. 43767/66. Heading H1B. An electrode suitable for use in a fuel cell comprising a gas adsorbing metal catalyst dispersed on support material which is held together by a binder, is characterized by the support material consisting of particles of carbon containing boron. Mixtures of boron and carbon (e.g. graphite) may be heated together, the boron becoming absorbed in the carbon, provided that there is less than the stoichiometric amount of boron to form boron carbide as this material is not suitable; carbon containing boron and also containing boron carbide, however, is highly suitable. The catalyst may be platinum (preferably deposited by decomposition of a platinum compound free of halogen e.g. diammino-dinitritoplatinum), silver, palladium, an alloy of platinum and ruthenium, or nickel boride. The binder may be polytetrafluoroethylene. Examples are given. |
