CO/sub 2/ recovery in molten carbonate fuel cell system by pressure swing adsorption

Carbon dioxide (CO/sub 2/) recycle configuration using pressure swing adsorption (PSA) is examined in the indirect internal reforming molten carbonate fuel cell (IIR-MCFC) system. It is shown that the CO/sub 2/ PSA makes the system efficiency higher than in an ordinary combustion process. A test plant was fabricated in order to evaluate the PSA performance in the IIR-MCFC system. The experimental results with respect to CO/sub 2/ recovery ratio, purity, and pressure fluctuations in both electrode chambers are acceptable.<
