【Abstract】 H₂-fuelled, polymer electrolyte membrane cells （PEMFC） have caught considerable attention as a cleaner, more efficient system. Pt anodes are often poisoned by CO, so H 2rich mixtures should be essentially free of CO. Some techniques of purifying H 2rich gas were evaluated. The studies showed that preferential oxidation of CO was most straightforward and cost effective. In this work all kinds of preferential CO oxidation catalysts were reviewed. Emphasis was made on the study and development of Aubased catalysts.更多还原
