    摘要： A hybrid power generation system (10) for generating electrical power comprises a compressor (12) for producing a compressed oxidant and a recuperator (20) in flow communication with the compressor. The hybrid power generation system further comprises a fuel cell assembly (34) comprising a plurality of fuel cells in flow communication with the recuperator (20) to provide the compressed oxidant for the fuel cell assembly (34). The fuel cell assembly further comprises a cathode inlet (46) for receiving the compressed oxidant, an anode inlet (50) for receiving a fuel stream (58), an anode outlet (52) in flow communication with an anode exhaust stream (60) and a cathode outlet (48) in flow communication with a cathode exhaust stream (54), wherein at least a portion of the fuel reacts with the oxidant to produce electrical power. The hybrid power generation system further comprises a tail gas burner (38) in flow communication with the anode outlet (52) and the cathode outlet (48). The tail gas burner is configured for combusting a mixture of at least a portion of the anode exhaust stream (60) and at least a portion of the cathode exhaust stream (64) and producing a hot compressed gas. A control system is used for controlling the amount of the cathode exhaust stream (64) introduced in the tail gas burner (38) for stable combustion and reduction of fuel and carbon monoxide emission. The hot compressed gas from the tail gas burner is introduced to a turbine (14), where the hot compressed gas is expanded, thereby producing electrical power and an expanded gas.

    摘要： It is possible to rapidly start a fuel cell and perform temperature increase operation and temperature decrease operation at start/stop without providing a separate purge gas supply system. The solid oxide type fuel cell includes a reformer (21) or the reformer (21) together with a water vapor generator (22), and a heating device (24) for heating at least the reformer (21) which are arranged in a housing (20). In the fuel cell operation method, upon start or stop of the operation, the reformer (21) generates a reductive gas containing hydrogen by a partial oxidization reforming reaction or auto-thermal reforming reaction and supplies the reductive gas to the fuel electrode side of the generation cell, thereby increasing or decreasing the temperature of the fuel cell while maintaining the fuel electrode atmosphere in a reduction condition.

    摘要： A fuel cell system and an operating method thereof capable of reliably reducing fuel crossover and electrolyte film deterioration is provided. A fuel cell system (100) includes: a fuel cell (104) which includes an electrolyte film (104a); aqueous solution circulation means which provides circulatory supply of aqueous methanol solution to the fuel cell (104); fuel supply means which supplies the aqueous solution circulation means with methanol fuel that has a concentration not lower than that of the aqueous methanol solution; and a main switch (152). After the main switch (152) is turned OFF, a CPU (172) controls fuel supply operation of the fuel supply means so that the amount of fuel supply to the aqueous solution circulation means is decreased. Thereafter, power generation operation of the fuel cell (104) is controlled so that the power generation is stopped, with the concentration of aqueous methanol solution lower than before the main switch (152) was turned OFF. The produced energy during shutdown is stored in a secondary battery.
