Abstract
Abstract A solid oxygen-ion electrolyte fuel cell electrically coupled directly to a solid oxygen-ion electrolyte water dissociation cell (for the generation of hydrogen) is described. Hydrocarbon fuel is reacted with air and/or steam to produce a reducing gas mixture, which is admitted to the coupled cells to depolarize the anode of the dissociation cell and serve as fuel for the fuel cell. The fuel cell produces low voltage direct current useable, as produced, by the dissociation cell and, when these cells are directly coupled electrically, either cell will automatically adjust to altered operating conditions or cell characteristics of the other cell.
