(US5332630-A)      The system for recharging a battery comprises a rechargeable battery and a fuel cell system connected to the battery, adapted for providing power to continuously recharge the battery corresponding to a varying load placed on the battery. The temp. of the fuel cell system is controlled independently of the power output of the fuel cell system. A supply of fuel and oxidiser is provided to the fuel cell system, the fuel cell system being adapted for the conversion of the fuel to electricity.    A voltage regulator is provided for regulating the power supply to the rechargeable battery. The battery further comprises electrical leads to power an electric motor in an electric vehicle. The fuel cell system is adapted for selectively providing power directly to the electric motor.    USE -   On-board recharging system for a battery-powered electric vehicle.    (JP7504063-W)      The power supply system includes a rechargeable electric battery (12) connected to the electric drive motor (16), which is recharged via a fuel cell system (10), supplied with fuel and oxidiser, converted via the fuel cell system into electricity. Pref. the power supplied to the battery is regulated via a voltage regulator (14) between the fuel cell system and the battery.    The fuel cell system can be adapted for directly supplying the drive motor with electrical energy, or for providing power off-board the vehicle. Pref. the fuel cell system uses a stack of solid oxide fuel cells operating at a temp. of up to 2000 degrees C.    ADVANTAGE -   Allows vehicle range and power to be comparable with traditional vehicle having IC engine. Does not require interruptive recharging from off-board source.
