Abstract: A method of shutting down a fuel cell system includes a first step of supplying hydrogen gas and air to a fuel cell stack to thereby cause the fuel cell stack to generate electricity, and a second step of stopping supply of the hydrogen gas, and then supplying air to the fuel cell stack so as to cause the fuel cell stack to generate electricity upon detection of a command to shut down the fuel cell stack. In the second step, when the pressure of the hydrogen gas is lowered to a preset lower-limit value based on an anode pressure, which actually is measured, the fuel cell stack is caused to stop generating electricity.

Abstract: A fuel cell system that can quickly transition to idling stop and can suppress degradation of the electrolyte membrane and decline in cell voltage during idling stop, without requiring a discharge resistor to be provided, and a control method thereof are provided. A fuel cell system (1) includes a fuel cell (10) configured by layering a plurality of fuel cell cells that generate power by reactant gas being supplied thereto, and a supply device 20 that supplies reactant gas to the fuel cell (10), in which idling stop control is initiated to supply air of a lower flow rate than during idling power generation to the fuel cell (10), while producing lower current than during idling power generation from the fuel cell (10), in a case of a predetermined condition being established during idling power generation.

Abstract: A method includes: determining whether or not an elapsed time since stopping of power generation of a fuel cell until an operation start instruction to start a fuel cell system is detected is shorter than a specified time, if the operation start instruction to start the fuel cell system is detected after the power generation of the fuel cell is stopped; setting, as a first amount, an amount of replacement of a fuel gas on an anode side, if it is determined that the elapsed time is shorter than the specified time; and setting, as a second amount, an amount of replacement of the fuel gas on the anode side, if it is determined that the elapsed time is longer than the specified time. The first amount is larger than the second amount.

Abstract: A fuel cell using an electrolyte-soluble fuel in which a solid film exhibiting a hydrogen ion- and/or hydronium ion-conducitivty is provided on the surface of an air electrode close to an electrolyte containing the fuel is disclosed.The solid film transmits hydrogen ions and hydronium ions, but it does not transmit water and oxygen in substance. Therefore, the leakage of electrolyte and the variation of the composition ratio of the electrolyte are not feared, so that the fuel cell can be used for a long time.
