A nitrogen concentration of fuel gas is estimated, and an amount of discharged fuel off-gas that is discharged from a fuel off-gas passage to outside by a discharging mechanism is controlled depending on the estimated nitrogen concentration. The nitrogen concentration, for example, can be estimated from a rate of pressure drop in the fuel off-gas passage during the discharge of fuel off-gas.

State of charge control for electric and hybrid vehicles. In one embodiment, a battery may be electrically connected to an electric motor to propel a vehicle. In such an embodiment, during vehicle operation a state of charge of the battery may fluctuate within a given state of charge range and may be regulated to a target state of charge. Such target state of charge may be set below the midpoint of the state of charge range. As the vehicle operates various devices may be controlled to regulate the state of charge to the target. In particular, an electric motor may be employed to lower the state of charge and an internal combustion engine may be employed to raise the state of charge. In other embodiments, regenerative braking, solar power or the like may be employed to raise the state of charge from at or below the target state of charge to the upper state of charge limit.

A gas/liquid separation device is connected to a discharge valve which can discharge fuel gas to the outside of a fuel cell system along with water accumulated in the gas/liquid separation device. A change in pressure at a portion upstream of the discharge valve, which occurs due to an opening operation of the discharge valve, is detected or estimated, and an integral value is obtained by integrating the amount of change in the pressure with respect to time from when the discharge valve is opened or a parameter value corresponding to the integral value is obtained. The integral value represents an amount of fuel gas discharged due to the opening operation of the discharge valve. It is therefore possible to reliably discharge a desired amount of fuel gas by deciding a closing time at which the discharge valve is closed based on the integral value or the parameter value corresponding to the integral value.

The invention relates to a radiator fan control for heat pump HVAC which can selectively reverse fan direction based on ambient temperature and reduce ice buildup on a liquid-gas converter. In one embodiment, the invention is an automobile with a liquid-gas converter located within an engine bay, a radiator located adjacent the liquid-gas converter, a first fan located adjacent the radiator, a fuel cell and motor with the inverter located adjacent the first fan, the fuel cell supplying electricity to the motor with the inverter to drive the vehicle. The invention can also include a temperature sensor located on an exterior surface the automobile to sense an ambient temperature, a heater core connected to the liquid-gas converter and located between the engine bay and the passenger area, and a control unit connected to the first fan, the temperature sensor, and the heater core.
