1,011,353. Fuel cells. GENERAL DYNAMICS CORPORATION. June 17, 1963 [June 27, 1962], No. 24077/63. Heading H1B. In a high temperature fuel cell 9 a gas impervious, stabilized zirconia solid electrolyte 15 is disposed between and in intimate contact with a gas porous solid anode 13 and a gas porous solid cathode 11, and either or both of the electrodes are firmly bonded to the electrolyte. The electrodes are porous matrices of non-conductive zirconia containing uniformly dispersed conductive catalytic material, and each matrix has substantially the same coefficient of expansion as the electrolyte to which it is bonded. The electrolyte is mainly zirconia with a small amount of one or more of rare earth oxides, alkaline earth oxides, scandia and yttria. The conductive anode material is one or more of nickel, chromium, cobalt, platinum, titania and urania, and the conductive cathode material is one or more of nickel oxide, copper oxide, manganese oxide, cobalt oxide, platinum, silver and silver-copper alloys. The electrode-electrolyte sandwich is held compressed by spring force (Fig. 1, not shown), and reacting gases are passed into contact therewith via passageways 79, 81, and exit therefrom via passageways 71, 73. A stack of cell units 131, Fig. 4, each comprising stabilized zirconia electrolyte 133, cathode 135, anode 137, has waffle-shaped conductive separators 139 between each unit 131, and non-conductive sealing gaskets 145, with conductive grids 147 interconnecting adjacent cell units. |
