The objective of this study has been to investigate the feasibility of removing carbon dioxide from hydrogen for two specific fuel cell system applications. In the first application, CO/sub 2/ is to be removed from H/sub 2//CO/sub 2/ mixture to produce pure hydrogen that can be used in an alkaline electrolyte fuel cell. In the second application CO/sub 2/ has to be added to the air entering the fuel cell cathode. Topics discussed include general considerations regarding hydrogen and carbon dioxide separation; specific separation methods; analysis of the alkaline fuel cell system; the molten carbonate system; experiments on hydrogen purification by electrolytic transfer; and experiments aimed at determining whether partially hydrophobic carbon particles would provide more efficient packing for CO/sub 2/ absorption towers than conventional packing.
