摘要

This paper presetns the results of an assessment of the requirements and technology for the proton Exchange membrane fuel cell as the electric power source for next-genertion spacecraft, and particularly as an accepted uprade to replace the current Orbiter alkaline fuel cell. As prt of the technology assessment, a commercially available 4-kW PEM fuel cell was tested for over 400 hours at NASA-johnson Space Center suing hydrogen and oxygen as reactarnts. The findings of this evaluation, as well as a short summary fo some test facility improvemtns and accomplishments as they relate to fuel cell testing in general, are presented improvements and accomplishments as they relate to fuel cell testing in general, are presented a short status of other items in the orbiter PEM Fuel Cell upgrade effort is also presented.
