The electrochemical hydrogen separator (EHS), under development at ERC, has several attractive features: The operating temperature (150{degree}C--200{degree}C) is higher than those associated with the currently available devices and is compatible with the low temperature shift reactors. The EHS can operate at atmospheric as well as elevated pressures and the product H{sub 2} is available at the feed stream pressure. High hydrogen recovery factor: 90% H{sub 2} recovery from feed streams containing less than 10% hydrogen is feasible. High hydrogen purity: The product H{sub 2} purity is >99% (dry basis) and is virtually independent of H{sub 2} concentration in the feed gas. The process is continuous. Low energy cost: Depending upon the operating conditions, the energy requirement varies between 2 to 6 kWh/1000 SCF of recovered hydrogen.
