A pressure vessel mounting structure includes: a manifold including a discharge gas passage branching from a general passage via which a container body communicates with a valve; a fusible plug valve configured to close the discharge gas passage and to, when the fusible plug valve is melted, open the discharge gas passage such that the high-pressure gas is discharged; a case including a bottom face portion covering the container body and the manifold from below in the vehicle up-down direction, the case including a bead placed near the fusible plug valve, the bead being formed by protruding a part of the bottom face portion upward in the vehicle up-down direction; and a communicating opening via which a space under a floor of a vehicle communicates with the fusible plug valve, the communicating opening being formed in a part of the bead, the part facing the fusible plug valve.

A vehicle installation structure for a fuel cell stack that includes: a framework member disposed at a vehicle lower side; a fuel cell stack that is disposed at a vehicle front section or a vehicle rear section, and that is elastically supported by the framework member via a vibration isolating member; and a drive motor that is disposed at a same section of the vehicle front section or the vehicle rear section as the fuel cell stack, that is separate from the fuel cell stack, and that is elastically supported by the framework member via a vibration isolating member such that a height position of at least one of an upper end, a lower end, or a height direction center of the drive motor is disposed between a height position of an upper end and a height position of a lower end of the fuel cell stack.

A method for controlling an operation of a fuel cell of a fuel cell vehicle is provided. The method includes detecting a state of charge (SOC) of a high voltage battery and determining whether the detected SOC of the high voltage battery is within or beyond a preset range from a minimum recommended SOC to a maximum recommended SOC. Power generation of the fuel cell is performed or stopped by comparing a required current of the vehicle with a preset current value required to enter a fuel-cell stop mode in which the power generation of the fuel cell is stopped and a preset current value required to release the fuel-cell stop mode.

Systems and methods for fueling (or charging) communication, for example between a hydrogen fueling station and a hydrogen powered vehicle (or an electric vehicle and charging station) may utilize near field communication as well as vehicle to infrastructure communication. Safety information, fueling or charging information, payment information, and other information may be transmitted, and the redundant nature of the communication permits fault recovery and improved process monitoring. In this manner, fueling and/or recharging is made safer, faster, and more efficient.

A fuel cell vehicle is provided. The fuel cell vehicle includes a fuel cell, a junction box that is disposed on the fuel cell and includes a first bus bar, a power controller that is disposed at the rear side of the fuel cell and includes a second bus bar, and a fastening part that fastens the first bus bar and the second bus bar in a fastening space to electrically connect the junction box and the power controller to each other. One of the junction box and the power controller includes a tool inlet to allow access to the fastening space from the outside.
