Abstract

A refuelable and rechargable metal-air FCB based power supply unit for integration into a device/system for generating and providing electrical power to at least one electrical-energy-consuming load device disposed therein. An external power source is used to recharge the metal-air FCB subsystems embodied therein. A control subsystem automatically transitions between discharging mode (wherein at least one metal-air FCB subsystem supplies electrical power to the electrical power-consuming load device) and a recharging mode (wherein the external power source is electrically coupled to at least one metal-air FCB subsystem to thereby recharge the metal-air FCB subsystem(s). The metal-air FCB subsystem(s) are refueled by manually loading and unloading metal-fuel from the metal-air FCB subsystem(s). Preferably, electrical power provided to the at least one electrical power-consuming load device is supplied solely by electrical power generated by discharging metal-fuel in the metal-air fuel cell battery subsystem(s).
