An electric component connection mechanism of a fuel cell stack includes a fuel cell stack body, terminal plates, end plates, and a housing. A plurality of fuel cells that generate electricity by electrochemical reaction of a fuel gas and an oxidant gas are stacked in the fuel cell stack body. The terminal plates are disposed on both ends of the fuel cell stack body in a stacking direction of the fuel cells. The end plates are stacked on the terminal plates on the sides opposite to the fuel cell stack body. The terminal plates include terminals that penetrate through and protrude out of the end plates. The terminals are connected to high-voltage cables. Moving mechanisms that support the terminal plates while allowing the terminal plates to advance and retreat in the stacking direction with respect to the end plates are provided.

A fuel cell vehicle includes a fuel cell, a gas supply unit, a friction brake system, a drive motor, an electric storage device, and a control unit configured to execute control of obtaining requested braking force with use of friction braking force and regenerative braking force and control of performing a scavenging process. When the fuel cell vehicle is in braking with the friction braking force and the regenerative braking force, the control unit is configured to determine whether or not a scavenging preparation condition is satisfied with use of the amount of stagnant water stagnating in the fuel cell, execute a responsiveness enhancement process when the scavenging preparation condition is executed, and execute a scavenging process when the responsiveness enhancement process is completed, and the amount of the stagnant water reaches a reference value.

This disclosure relates to an energy storage arrangement for a vehicle. In particular, the energy storage arrangement includes a battery unit provided in an intermediate space between adjacent fluid tanks. Relative to the above-discussed prior art, this disclosure provides an improved energy storage arrangement which uses the otherwise unused intermediate space between two adjacent fluid tanks. Thus, this disclosure provides a space-saving, efficient, and cost-effective arrangement.

A current limiting method of a fuel cell stack is capable of preventing current of the fuel cell stack from rapidly dropping to prevent jerking or shock from occurring while a vehicle travels. The method includes: determining whether performance deterioration of a unit cell of the fuel cell stack has occurred, employing a feed forward control type current limiting logic of the fuel cell stack before an output of the fuel cell vehicle is lowered, decreasing the current of the fuel cell stack to a predetermined level by the feed forward control type current limiting logic, and gradually restoring the current of the fuel cell stack to a maximum current usage value from a point in time when the current of a load is used.

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.

In a fuel cell system, a stack case which stores a stack body of power generation cells and an auxiliary device case are separated by a partition wall. An outer periphery of at least one end fluid passage provided at least at the uppermost position, among the fluid passages of the stack body, has an adjacent outer peripheral portion provided adjacent to an outer marginal portion of the stack body. The partition wall includes a facing portion. The facing portion faces an area that lies between the adjacent outer peripheral portion and the stack case and outside the outer marginal portion. At least part of a ventilation connection port configured to connect the inside of the stack case with the inside of the auxiliary device case is provided in the facing portion. The ventilation connection port has a curved shape formed along the adjacent outer peripheral portion.
