  • Method of controlling fuel cell system by comparing pressures in fuel gas path
    Patent number: 10355292
    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.
