An apparatus and method are disclosed for eliminating the chemical energy of fuel remaining in a pressurized fuel cell generator (10) when the electrical power output of the fuel cell generator is terminated during transient operation, such as a shutdown; where, two electrically resistive elements (two of 28, 53, 54, 55) at least one of which is connected in parallel, in association with contactors (26, 57, 58, 59), a multi-point settable sensor relay (23) and a circuit breaker (24), are automatically connected across the fuel cell generator terminals (21, 22) at two or more contact points, in order to draw current, thereby depleting the fuel inventory in the generator.

The drive system as defined in claim 5, wherein: the controller further functions to: supply the high temperature reducing gas to the catalyst reaction part during a required reactivation time determined according to the deteriorate condition of the catalyst when it is determined that the deterioration of the catalyst has reached a first deteriorate condition. 8. The drive system as defined in claim 5, wherein: the controller further functions to: store a required reactivation time according to the deteriorate condition of the catalyst when the drive system has stopped, and supply the high temperature reducing gas to the catalyst reaction part during the stored reactivation time when the drive system starts on the next occasion. 9. The drive system as defined in claim 1, wherein, when the catalyst of the catalyst reaction part has not been used for a long period, when it is initially used or when it is severely oxidized, the controller further functions to supply high temperature reducing gas to the catalyst reaction part during a predetermined time when the drive system starts. 10. The drive system as defined in claim 5, comprising: a sensor which detects one of the temperature, gas composition and gas flowrate at the outlet of the catalyst, and the controller further functions to: determine the catalyst deterioration based on the detection amount at the outlet of the catalyst. 11. The drive system as defined in claim 5, comprising: sensors which detect one of the temperature, gas composition and gas flowrate at the inlet and outlet of the catalyst, and the controller further functions to: determine the catalyst deterioration from the ratio of the detection amounts at the inlet and outlet of the catalyst. 12. A drive system for a fuel cell, comprising: a catalyst reaction part which has a catalyst and generates gas supplied to the fuel cell by a catalytic reaction in the catalyst; a start-up combustor which is provided upstream of the catalyst reaction part and receives a supply of fuel and air to perform combustion; means for generate high temperature reducing gas in the start-up combustor by burning the supplied fuel and air; and means for supplying the high temperature reducing gas to the catalyst reaction part, and reduce the catalyst in the catalyst reaction part.
