Title: Anode electrode for cell with molten carbonate type fuel
Inventor: KOSEKI KAZUO
IPC: H01M4/86
Filed: 1987-05-07
Abstract: PURPOSE:To enhance the performance and stability of electrode by furnishing a gas side electrode layer consisting of porous metal sintered body, which is alkali resistant and hard to creep, and an electrolyte plate side electrode layer consisting of porous metal sintered body which is alkali-resistant and feasible to creep. CONSTITUTION:In an anode electrode, a porous metal sintered body, which is alkali-resistant and hard to creep, is used for the gas side electrode layer 3B. As the metal sintered body is used, for ex., a sintering of Ni-Co alloy or Ni-Cr alloy or a mixed sintering of Ni and oxides. Because this gas side electrode layer 3B is hard to creep and has less change in the porosity, the electrode output is stabilized. The electrolyte plate side electrode layer 3A is made in a sintering of, for ex., Cu or Ni. Because feasible, these materials can easily conform to unevenness of the electrolyte plate 2 consisting of a hard ceramic plate, that should increase the electrode output.
