Abstract

1,163,479. Fuel electrodes. ENGELHARD MINERALS & CHEMICALS CORP. 17 March, 1967, No. 12748/67. Heading H1B. A fuel electrode of a fuel cell comprises a porous supporting substrate and a mixture of a platinum group metal, as catalyst, supported on carbon black and a binder, this mixture being bonded to the substrate and within its pores and the carbon black having a surface area of 50-350 sq. metres per gram and a pore volume for all pores up to 30 mÁ pore diameter of no more than 0À4 c.c./gram. The total volumes of pores within certain pore size ranges may be as follows;- Less than 2 mÁ diameter-less than 0.05 c.c./g. 2-4 mÁ diameter-0-0À2-0À1 c.c./g. 4-30 mÁ diameter-up to 0À3 c.c./g. The particle size of the carbon black may be 5-400 mÁ and when packed under 140 Ib./sq. inch pressure the electrical resistance may be up to 2 ohm cm. Blacks specified are certain channel blacks and oil furnace blacks and combustion products of CH 4 , C 6 H 14 and C 7 H 16 . The catalyst, e.g. a mixture of Pt and Ru, may be introduced by slurrying the black with a solution of the metal chloride, adding caustic alkali to precipitate the metal oxide, reducing it, washing and drying it. It may then be activated by heating in H 2 . The ratio of carbon and catalyst may be such that the carbon-metal ratio is between 20: 1 and 1: 20. The binder may comprise particles of P.T.F.E., a silicone, a polyolefin, e.g. polyethylene, polytrifluorochloroethylene, polytrifluoroethylene or a copolymer of tetrafluoroethylene and hexafluoropropylene, the particles being 50-1000 mÁ in size. The catalyst/binder mixture may be applied to the substrate by pressure or by brushing as an aqueous emulsion. The support may be a Pt or stainless steel screen or a porous sheet of P.V.C., P.T.F.E., polyacrylonitrile, polyvinylidene chloride, glass fibres or asbestos. A fuel cell employing the invention is illustrated in Fig. 1. Fuel and oxidant chambers 17 and 18 are separated from electrolyte 8 by electrodes 6 and 7. Fuel electrode 6 comprises porous substrate 9, catalyst layer 11 and current collector 14. Oxidant electrode 7 comprises porous substrate 10, particulate metal layer 12 and current collector 13. Fuel may be H 2 , MeOH, EtOH, propane, ethane or butane. Electrolyte may be aqueous H 3 PO 4 , H 2 SO 4 , NaOH or KOH. The current collectors may be Pt gauze.
