Fuel Cell Based Uninterruptible Power Supply (UPS) for Computers

Funded by Arizona Public Service - Pinnacle West Corp., Phoenix, Arizona

Arizona Public Service (APS), a local electric utility company, donated three fuel cell stacks, ranging from 250 W to 2000 W, for the research and development activities of Arizona State University. One of the H-Power PEM250 fuel cell stacks was chosen to power a single personal computer. After extensive investigation, appropriate dc-dc converter and dc-ac inverter were identified and integrated with the fuel cell stack and the computer. This UPS system is fully operational and it has been determined a full 2500 psi tank of hydrogen could support a single PC for about 40 hours.
