Compact Lightweight Power PEMFC Operating from a Unique Hydrogen Generating System.

Abstract

The goal of this program was to investigate the feasibility, for the military, of a 120-watt, 20,000- watt-power source weighing near ten pounds. An air breathing proton exchange membrane fuel cell (PEMFC) utilizing hydrogen from Lithium Borohydride (LiBH4) could theoretically meet this specification. Giner, Inc. has established that a hydrogen generator, utilizing LiBH4, provides a hydrogen current flux of 150 Amps/sq ft with about 60% long-term utilization. Additionally, Giner, Inc. demonstrated a 120-watt fuel cell system, which operated at approximately 12 volts at 100 Amps/sq ft (10 amps through a 0.1 -sq ft active area). Integrating the two systems will require further effort and development work. (MM)
