Abstract:

The HOPE Hydrogen-Oxygen Primary Extraterrestrial Fuel Cell Program is a multi-phase effort to advance the state-of-the-art of fuel cells by obtaining permanence data under actual space conditions. Phase I of this program resulted in the development and test of a 35-cell 25-watt28-volt space configuration fuel cell module. The HOPE spacecraft, fuel supply tanks, pneumatics, and thermal systems were designed and fabricated to provide operating capability in orbit for 7 days at 50 watts and be compatible with the Blue Scout launch vehicle. A series of development tests was conducted to verify water removal, thermal design, and 30-day shelf-life of the fuel cell. The 35-cell module was subjected to a series of performance tests. During the last test, it performed continuously for 7 days at an average of 27 watts29.5 volts. Following this test, the module delivered rated power without interr ption during vibration tests simulating Blue Scout booster environment.
