Abstract
A miniaturized fuel cell assembly to power portable electronic equipment includes a hydride hydrogen storage unit, a control unit for controlling the flow of hydrogen, a hydrogen supply device interconnecting the hydrogen storage unit and the fuel cell body, and an air feed device to supply oxygen necessary for the generation of electricity. The fuel cell assembly may also have an air feed device to cool the interior of the equipment, including a water retention device for recovering and retaining water formed in the fuel cell body, and a humidifying device using the recovered water to humidify the hydrogen to be supplied to the fuel cell body. The miniaturized fuel cell assembly facilitates the effective transfer of waste heat from the fuel cell to the hydrogen storage unit, and as a result of its ability to be used repeatedly, can be utilized for a greater length of time than a conventional primary or secondary power cell.
