..., or in the case of pure hydrogen, as fuel gas, by electrolysis. For these generating processes energy is required. This generally leads to a deterioration of SOFC-system efficiencies. At state of the art combined processes, the reformation or gasification reactor and the SOFC are usually separated. The heat...
