摘要： The invention relates to a method for operating a fuel cell system during a heating phase or another transient operating phase or a method for adjusting a relative humidity of a cathode operating gas. The fuel cell system comprises a fuel cell stack with anode and cathode chambers separated by polymer electrolyte membranes, and a cathode supply for supplying and discharging the cathode operating gas into and out of the cathode chambers, as well as a cooling system for controlling the temperature of the fuel cell stack. The method has the following steps: determining an inlet temperature of the cathode operating gas at the inlet of the fuel cell stack, setting a coolant setpoint temperature at the inlet of the fuel cell stack to a value which is equal to or less by a predetermined amount than the inlet temperature of the cathode operating gas, and controlling the cooling system so that a coolant temperature prevailing at the inlet of the fuel cell stack at least approximates the coolant setpoint temperature.

摘要： An example method of decontaminating a fuel reactant stream for a fuel cell flows the fuel reactant stream through a fluidized ammonia dissolving media, while simultaneously flowing water through the fluidized ammonia dissolving media to separate contaminants from the fuel reactant stream into a separated contaminant and water stream. The separated contaminant and water stream from the fluidized bed is accumulated within an accumulator, circulated through a water-control loop, and decontaminated by flowing the stream through an ion exchange bed secured in fluid communication with the water-control loop. A decontaminated water stream from the ion exchange bed is circulated back through the ammonia dissolving media. A temperature of the fuel reactant stream is controlled upstream of the fuel reactant stream entering the separator scrubber to produce a predetermined temperature of the fuel reactant stream passing through the separator scrubber.

摘要： An alternating current uninterruptible power supply system includes a first power feed line, a second power feed line, a switchover relay, a converter, a power switch, a fuel cell, a system control board, a battery, and an inverter. If it is determined that electric power supply from a commercial alternating current power source has stopped for a first time or longer, a system control part of the system control board switches the switchover relay from a first state to a second state. Then, on the basis of the state of the electric power of the first power feed line, the system control part determines whether or not stopping of the electric power supply from the commercial alternating current power source has continued for a second time or longer. After that, if it is determined that the stopping of the electric power supply from the commercial alternating current power source has continued for the second time or longer, the system control part starts power generation of the stack.

摘要： An anode exhaust recycle turbocharger (100) has a turbocharger turbine (102) secured in fluid communication with a compressed oxidant stream within an oxidant inlet line (218) downstream from a compressed oxidant supply (104), and the anode exhaust recycle turbocharger (100) also includes a turbocharger compressor (106) mechanically linked to the turbocharger turbine (102) and secured in fluid communication with a flow of anode exhaust passing through an anode exhaust recycle loop (238) of the solid oxide fuel cell power plant (200). All or a portion of compressed oxidant within an oxidant inlet line (218) drives the turbocharger turbine (102) to thereby compress the anode exhaust stream in the recycle loop (238). A high-temperature, automotive-type turbocharger (100) replaces a recycle loop blower-compressor (52).

摘要： A fuel cell system of the present invention includes: a fuel cell supplied with fuel gas and oxidizing gas to generate electricity; a fuel gas supply unit supplying the fuel gas to the fuel cell; an oxidizing gas supply unit supplying the oxidizing gas to the fuel cell; an aftercooler cooling the oxidizing gas supplied to the fuel cell by heat exchange with a coolant; an oxidizing gas temperature detector detecting temperature of the oxidizing gas; and a coolant circulation controller starting circulation of the coolant when the detected temperature of the oxidizing gas exceeds a predetermined value. The predetermined value is set to a value of not higher than a minimum electricity generation temperature of the fuel cell, and a circulation timing and flow rate of the coolant for the aftercooler are controlled such that the supplied oxidizing gas does not become cold. This enables the fuel cell to generate electricity at cold start-up.
