✦ Synopsis

Performance of the cylinder type high temperature fuel cell was calculated on the basis of fuel flow. Fuel composition change, output current, cell length, and electrolyte and/or electrode resistance were explicitly taken into account. Fuel consumption profile, current density distribution, and potential profiles in the electrodes were numerically calculated. From these calculations, it was evident that the cell length is the most important factor in realizing a uniform current density distribution in the cell. A model stack comprised of 2 cm long 10 unit cells connected in series using Ce~_~Gd~O~_~/e electrolyte and LaCoO~ cathode operating at 750°C gives a power density of 220 mW/cm z.
