    Abstract: A first holder holds a plurality of layers associated with a battery submodule that is being assembled. A first and second pair of actuators, while the plurality of layers is held by the first holder, extend so that the first and second pair of actuators apply pressure to the plurality of layers. While the first and second pair of actuators are extended and applying pressure to the plurality of layers, the first holder retracts. A second holder holds a container associated with the battery submodule that is being assembled and extends so that the container gradually surrounds the plurality of layers. While the container gradually surrounds the plurality of layers, the first and second pair of actuators sequentially retract.

  • Patent number: 10720657
    Abstract: A fuel cell system includes: a pressure regulating valve that reduces a pressure of a fuel gas; a fuel gas supply passage having a first passage extending between a fuel cell and the pressure regulating valve and a second passage extending from the pressure regulating valve via a cutoff valve to a fuel gas supply source; a pressure sensor that detects a pressure of the fuel gas inside the first passage; and a controller to which the cutoff valve and the pressure sensor are connected. When a pressure value detected by the pressure sensor is an abnormal value, the controller closes the cutoff valve and performs pressure reduction processing for the first passage. Thereafter, the controller judges that the pressure regulating valve has failed when the pressure value detected by the pressure sensor has lowered, whereas the controller judges that the pressure sensor has failed when the pressure value detected by the pressure sensor has not lowered.
