Portable fuel cell power generator

The proliferation of electronic equipment in the market-place is driving the growth of portable power generators. The ability to store a sufficient amount of energy is the key issue for applications requiring high power levels or extended operation. The source of this energy, measured in watt-hours, can be either batteries or fuel for energy conversion systems. This paper compares energy storage methods and shows that fuel cell systems are well suited for portable power applications due to their use of high energy density storage capabilities.
