摘要： The present invention relates to a fuel cell operation method in which a fuel cell 11 that generates power using hydrogen gas and oxidant gas as reaction gas is operated at an operating pressure that corresponds to a required power generation state. A hydrogen sensor 54 that detects hydrogen density is provided in a vicinity of the fuel cell 11, and based on values detected by the hydrogen sensor 54 and on the amount of hydrogen leakage at the current operating pressure and on the characteristics of the fuel cell 11, an operating pressure is predicted at which the hydrogen leakage amount from the fuel cell will not exceed a predetermined value, and the fuel cell 11 is operated while limiting the operating pressure to below the predicted operating pressure.

摘要： 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.

摘要： A fuel cell system includes a replacing unit for replacing a gas remaining in the anode of the fuel cell with the anode gas supplied anew by the anode gas supply unit when starting up the fuel cell. The amount of the anode gas is set to be lower, if the operation condition determining unit determines that the last operation was performed in a low-temperature and short-time operation mode. The operation condition determining unit sets the amount of the anode gas so that the gas remaining in the anode can be replaced with the anode gas with an entire anode capacity if the anode was been scavenged while no electro-chemical reaction was progressing in the fuel cell. The present invention can set the amount of anode gas appropriately when starting up the fuel cell.
