To restrain deterioration of fuel cells while preventing a battery from being overcharged, a fuel cell vehicle includes a motor for providing torque to wheels, a battery for storing electric power to provide the stored electric power to the motor, and a FC stack for generating electric power to provide the generated electric power to the motor and the battery. A battery charge level determining module determines a battery charge level of the battery, and a FET is configured to connect or disconnect the FC stack to the motor and the battery. A controller is configured to cause the FET to disconnect the FC stack from the motor and the battery and allow power generation by the FC stack when the determined battery charge level by the battery charge level determining module is greater than or equal to a first predetermined threshold.

Vehicle electric power supply control system and vehicle

A fuel cell stackadapted for an electrochemical reaction of a fuel gas to generate an electric power is provided with a working point measuring sectionfor measuring a generation voltage and a generation current of the fuel cell stack, and connected to a controllerincluding an output characteristic map memoryfor storing output characteristics of the fuel cell stack, and a potential output power estimatorfor estimating a potential output power of the fuel cell stackbased on a combination of a current generation voltage Vand a current generation current Imeasured by the working point measuring sectionand pieces of information stored in the output characteristic map memory

Fuel cell system

The grill shutter is disposed between the front grill and the air intake duct. The grill shutter is capable of opening or closing shutter members and regulating positions of the shutter members when being opened. When a maximum supplied flow rate of air provided by the wind during running is greater than a flow rate of air required for the hydrogen fuel battery, the required flow rate of air is established only by opening/closing control of the shutter members through a grill shutter opening instruction. If this is not the case, the grill shutter members are opened fully through the grill shutter opening instruction to maximize the volume of the wind during running taken in from the front grille. Additionally, a shortfall in the required flow rate of air for the hydrogen fuel battery is compensated for by actuating the blower through a blower speed instruction.

Fuel cell cooling system for vehicle and fuel cell-powered vehicle

An exhaust apparatus includes a lower side exhaust duct and an upper side exhaust duct which are branched vertically, and in that the lower side exhaust duct is extended toward the lower side of the vehicle from an exhaust outlet portion of the air-cooled fuel cell stack, and the downstream end portion of the lower side exhaust duct is opened at a lower portion of the front compartment, while the upper side exhaust duct is extended toward the upper side of the vehicle from an upper portion of an outer wall of the lower side exhaust duct, the outer wall extending toward the lower side of the vehicle, and the downstream end portion of the upper side exhaust duct is opened between the rear end portion of the front hood and the front end portion of the front window.
