TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: The fuel cell further comprises an interconnect that interconnects the fuel cells. The interconnected fuel cells form a power generation system. The fuel cell further comprises a precursor layer formed between the electrolyte and the fuel electrode, the precursor layer composition comprising zirconia and having a thickness of 5-20 microns. Preferred Parameter: The powder has a gun feed rate of 6-30 g/minute, and a distance of less than 4 inches between the gun and the electrolyte. The spray gun has a discharge voltage of 30-60 volts, a current of 400-900 amperes, and a power of 10-40 kilowatts. The spray gun moves at a rate of 400-700 mm/sec and the electrolyte makes 2-40 revolutions around the spray gun to form the fuel electrode.
