Jul 18, 2018 A modelling study of SOFC coupled with steam and dry coal gasification indicated that the DC-SOFC system is capable of power densities 1.0 Wcm 2 with H 2 O steam recycle, and power densities ranging from 0.2 to 0.4 Wcm 2 with CO 2 recycle. This result also suggests that the DC-SOFC system performs better with steam than with CO 2 gasification.
