Abstract: A method of controlling a fuel cell system includes supplying a fuel gas from a fuel-gas storage container to a fuel cell via a drive valve provided in a fuel-gas path. A first pressure is detected in the fuel-gas path between a first decompression mechanism and a second decompression mechanism. A second pressure is detected in the fuel-gas path between the second decompression mechanism and the drive valve. An on-off valve is opened. The on-off valve is provided in a bypass path. The first pressure and the second pressure are compared after the on-off valve has been opened. The fuel cell system is controlled to decrease electric power generated by the fuel cell or to stop generating electric power in the fuel cell when the first pressure is not substantially equal to the second pressure.

Abstract: A fuel cell system includes a plurality of electricity generation systems and a connection flow path through which fuel flows between the plurality of electricity generation systems. Each electricity generation system includes a fuel tank, a fuel cell stack, a fuel flow path, a first pressure sensor, a shutoff valve, a control device, and a branch portion. The first pressure sensor is arranged in the fuel flow path and detects a fuel pressure on the fuel tank side. The shutoff valve is arranged on a downstream side of the first pressure sensor in the fuel flow path, and is switched between flow and shutoff of the fuel by opening and closing. The branch portion branches from the fuel flow path on a downstream side of the shutoff valve in the fuel flow path. The connection flow path connects the mutual branch portions of the plurality of electricity generation systems.

Abstract: A fuel-cell vehicle includes a storage container, a fuel cell system, a state detector, a transmitter, a request detector, and a controller. The controller includes a signal generator and a communication starting device. The signal generator is configured to determine a transmission value indicating a physical state detected by the state detector so as to generate a data signal in accordance with the transmission value. The signal generator is configured to set the transmission value to a reference value preset based on the physical state detected by the state detector if the fuel cell system is not running and configured to set the transmission value to a value obtained by correcting the reference value so that an amount of the fuel gas to be monitored by an external filling device increases if the fuel cell system is running.
