Abstract
A fuel cell generator including arrays of a plurality of fuel cell units each including a solid electrolyte partition, a fuel electrode provided on one side of the solid electrolyte partition, an air electrode provided on the other side of the solid electrolyte partition, and an inner space having opposite open ends. The end openings of the inner spaces of the fuel cell units are opposed to each other and a fuel gas supply tube or oxidizing gas supply tube is extended through the inner spaces from a fuel gas supply inlet or oxidizing gas supply inlet. A desired long array can be provide by changing the number of short fuel cell units in the array to thereby easily limit thermal gradient in each fuel cell unit to improve electricity generating efficiency of the whole fuel cell generator.
