摘要： A fuel cell system employs at least two fuel cell stacks electrically coupled in parallel to reduce the load turndown ratio of the fuel cell stacks. Fewer than all fuel cell stacks may be operated where the power demand permits. An oxidant supply subsystem may cease supplying oxidant to one of the fuel cell stacks to stop operation (power production) from the fuel cell stack. The fuel cell stacks may take turns at being the non-operating fuel cell stack.

摘要： A fuel cell power plant comprises a fuel cell stack (1) constituted by aplurality of fuel cells which perform electric power generation by means of areaction of hydrogen and oxygen. A controller (16) determines whether or notmoisture inside the fuel cell stack (1) is frozen, and if the moisture is frozen,the controller (16) causes the fuel cell stack (1) to perform intermittent electricpower generation via an inverter (27) while continuing to supply oxygen to thefuel cell stack (1). The fuel cell stack (1) generates heat as a result of theelectric power generation, whereby moisture is generated in a cathode (9).During the periods in which electric power generation is not performed, theoxygen which is supplied to the cathode (9) of the fuel cells scavenges thegenerated moisture, thereby ensuring the supply of oxygen to the cathode (9)during electric power generation.

摘要： A power plant system (110) produces utility grade electrical AC power from gaseous or liquid hydrocarbon fuels using a fuel cell stack (186) employing ion exchange membranes. The fuel is desulfurized, mixed with water, heated and vaporized before being introduced into a reformer (168). The reformer (168) produces a hydrogen-rich gas (51) which is then directed through a series of heat exchangers (164), shift converters (172) and a selective oxidizer (142). The processed fuel stream is combined in the fuel cell stack (186) with a pressurized oxidant stream to generate DC power. Oxidant pressure is supplied by compressors (130, 134) driven by turbines using heated system exhaust gases. The DC power is converted into utility grade AC power (195) using an inverter (210) augmented by a battery peaking unit (212) for rapid load following. The water generated in the fuel cell stack (186) is recycled and used to cool the fuel cell stack and to humidify the fuel stream and oxidant stream prior to their introduction to the fuel cell stack (186).
