Abstract

The invention provides a device for generating energy, utilizing a fuel cell. Air is freely guided to the fuel cell, while a fuel gas is provided to the fuel cell from a pressurized fuel supply via a regulator. The portable power supply is most applicable to use with handheld electric devices, and contains a fuel storage means (110) for storing a supply of fuel, a fuel delivery means (120) connected to the fuel storage means, an energy conversion device (140) connected to the fuel delivery means for converting the fuel to electricity. The fuel storage means, the fuel delivery means, and the energy conversion device are all contained in a volume less than 500 cubic centimeters.
