1,113,949. Fuel cells. GENERAL ELECTRIC CO. 29 Oct., 1965 [30 Oct., 1964], No. 45900/65. Heading H1B . A layer of 50 volume per cent of nickel dispersed in a solid oxygen-ion member is adhered to a layer of the oxygen-ion member. The nickel-solid oxygen ion member acts as the anode and the oxygen ion layer as the electrolyte of a fuel cell. The composite electrodeelectrolyte member may be planar, tubular or cup-shaped. A cathode layer is adhered to the other side of the electrolyte layer in a fuel cell. Solid stabilized zirconia or solid doped thoria may be used as the oxygen ion material. The composite-electrode-electrolyte member is prepared by grinding lithium carbonate and nickel oxide in ethanol and drying and calcining the mixture in air at 1500‹ C. for 30 minutes to produce a non-stoichiometric compound. The lithiated nickel oxide compound is crushed, ground, sieved and mixed with an aqueous slurry of stabilized zirconia and the resultant mixture is painted on to a surface of a stabilized zirconia member. The assembly so formed is fired in air, cooled and then reheated in hydrogen to reduce the nickel oxide to nickel. The cathode may be silver or doped tantalum peroxide. |
