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 vehicle fuel cell apparatus includes a fuel cell stack configured to take in air as a reaction gas and a coolant through an air intake aperture area, and discharge temperature-raised air through air discharging aperture areas. An air suction duct, air discharge ducts, and air discharge fans take in air to the air suction duct. The air discharge ducts have air discharge ports in the vicinity of the air suction duct. The air suction duct is formed with first air intake ports opening at its upstream end portion, and second air intake ports opening at locations nearer to the air discharge ports of the air discharge ducts than the first air intake ports. The second air intake ports are provided with shutters. The arrangement provides a vehicle fuel cell apparatus having enhanced operability in situations involving low-temperature outside air, and allows for enhanced mountability to vehicles.

Vehicle fuel cell apparatus with improved air intake

An object is to supply a sufficient amount of air to a fuel cell stack in a fuel cell vehicle when the fuel cell stack is mounted below a floor, the fuel cell stack configured to draw in air through an intake duct and discharge air to the exterior through an exhaust duct. An air introduction surface () faces upward or downward in a vehicle upper and lower direction, an intake passage portion () of the intake duct () extends along the air introduction surface () and vertical walls () of left and right end portions of the fuel cell stack () while a pair of air introduction ports () opens in left and right end portions of the intake passage portion (), and an exhaust passage portion () of the exhaust duct () extends along an air discharge surface () and vertical walls () of front and rear end portions of the fuel cell stack () while a pair of air discharge ports () opens in front and rear end portions of the exhaust passage portion ().

Fuel cell vehicle

Provided is a cooling structure for vehicle electrical components that is capable of solving problems due to water contained in intake air. Air used in an electricity generation reaction and air necessary for self-cooling is supplied to a fuel cell stack () via an intake duct (). Dust and chemical substances in the air are removed by a dust/chemical substance filter () provided on the fuel cell stack () side within the intake duct (). Furthermore, air and water are primarily separated by a water filter () provided in the intake duct () upstream by a prescribed distance in the air flow direction from the dust/chemical substance filter (). Therefore, water in the intake air does not reach the dust/chemical substance filter () and the fuel cell stack (), and various problems due to water contained in the intake air can be solved.

Air intake device for fuel cell vehicle

A detachable and portable fuel cell power unit which may be used with a vehicle. Said power unit with a unitary housing containing: a fuel reservoir for storing fuel; at least one electrochemical fuel cell stack for delivering electrical power; a fueling port in an outer surface of the housing; and an airflow path extending between a first inlet port on an outer surface of the housing and a first outlet port on an outer surface of the housing, via cathode elements in the at least one fuel cell stack. Said unit includes a control circuit for interfacing with a power controller on the vehicle for determining allowable operating conditions.
