Electrolysis propulsion for spacecraft applications [PDF]
33rd Joint Propulsion Conference and Exhibit, 1997 Electrolysis propulsion has been recognized over the last several decades as a viable option to meet many satellite and spacecraft propulsion requirements. This technology, however, was never used for in-space missions. In the same time frame, water based fuel cells have flown in a number of missions.
