The energy efficiency of hydrogen recovery from mixtures of CO 2 , H 2 O, and H 2 by a polymer electrolyte hydrogen pump (PEHP) has been evaluated. The PEHP pumps protons across the polymer electrolyte, producing [99.99% pure H 2 and a concentrated CO 2 stream. Single stage PEHP experiments recovered 65% of the hydrogen with an energy efficiency of 50%. The(More)
