Solid Oxide Electrolysis Cell co–methanation supported by Molten Carbonate Fuel Cell—a concept
Abstract
The paper presents a concept of coupling a Solid Oxide Electrolysis Cell with a Molten Carbonate Fuel Cell forco–electrolysis of H2O with CO2 for generating synthetic fuel (methane based) for an electricity storage applicationon a larger scale. The concept is focused on coal/natural gas fired power plants for upgrade as peak energystorage. MCFC anode and SOEC cathode are exposed to the same flow, SOEC produces hydrogen for MCFCand MCFC delivers CO2 for methanation processes. Both electrodes have compatible polarity, thus they can bedirectly connected by the current collector and there is no need to apply bipolar plates. On the other side, SOECwill release oxygen to the flue gases and MCFC will capture oxygen and carbon monoxide, thus at the outlet will bea flow with increased oxygen content and decreased carbon dioxide concentration. The concept requires detailedelectrochemical, chemical, and thermal simulations.References
