Abstract
The air supply apparatus for fuel cell system serves to supply air to the cell cathode and the combustion section of the reformer in the fuel cell system and recover energy from exhaust gases being discharged from the system. The apparatus has a compressor for supply of air to the system, an exhaust gas turbine for driving the compressor through recovery of energy from the system exhaust gas, an auxiliary combustor for compensating deficiency of the energy being recovered, if any, and pipe lines connecting those parts. The auxiliary combustor particularly employs a combustion catalyst in its combustion section. The apparatus secures stable combustion of the fuel gas in the auxiliary combustor, and its operation displays improved stability against any load change or partial load.
