Using A Polymer Electrochemical Hydrogen Pump for Energy Efficient Recovery of Hydrogen from Reformate Streams
Polymer electrolyte membrane fuel cells are traditionally used in a galvanic mode to produce electrical energy from chemical reactions. However, when operated in an electrolytic fashion they can function as a polymer electrochemical hydrogen pump (PEcHP). PEcHP selectively oxidizes and transports hydrogen across the polymer membrane while leaving charged neutral species behind. This technology may prove especially useful in purifying hydrogen from reformate streams, which consists primarily of hydrogen and carbon dioxide. The specific aim of this project was to determine the performance of the PEcHP under various reformate ratios, temperatures, and flow rates. We hope to optimize this process so as to provide a more energy efficient means of industrial hydrogen purification in the future.
