The components, operating mechanisms, and material for the fabrication of high temperature solid electrolyte fuel cells are described, along with features of a working prototype. The solid electrolyte fuel cell operates at temperatures from 800-1000 C, allowing some impurities in the fuel, and necessitating larger sized units for economic operation. Stabilized zirconia is employed as an electrolyte with high ionic conductivity, and the movement of oxygen ions in relation to the lattice points is discussed. Porous electrodes composed of zirconia or nickel alloys are chosen as anodes. A tubular shaped structure for the prototype allows three layers of fuel electrode, electrolyte, and an air electrode on the outer surface of a porous substrate tube of Al, and fabrication steps of the cell are provided. An air electrode is used as the cathode, and an output of 12 W is achieved with a flat output characteristic curve, indicating a potential long life.
