Abstract
Disclosed herein are a system and a method for the production of hydrogen. The system advantageously combines an independent high temperature heat source with a solid oxide electrolyzer cell and a heat exchanger. The heat exchanger is used to extract heat from the molecular components such as hydrogen derived from the electrolysis. A portion of the hydrogen generated in the solid oxide electrolyzer cell is recombined with steam and recycled to the solid oxide electrolyzer cell. The oxygen generated on the anode side is swept with compressed air and used to drive a gas turbine that is in operative communication with a generator. Electricity generated by the generator is used to drive the electrolysis in the solid oxide electrolyzer cell.
