Abstract
A hydrogen production plant includes an electrochemical autothermal reformer (EATR) that provides hydrogen to an electrochemical hydrogen compressor. The EATR includes an autothermal reformer region, a mixed ion conductor, and an anode supply region. The mixed ion conductor separates the autothermal reformer region from the anode supply region. An anode gas loop between the anode supply region of the EATR and anode section of the electrochemical hydrogen compressor cell circulates a mixture of hydrogen and a carrier gas therebetween. The carrier gas ensures proper partial pressures of hydrogen in the two regions. A difference in operating temperature between the EATR and the electrochemical hydrogen compressor is exploited by heat exchangers which efficiently enable certain heating and cooling functions within the combined system.
