An electrical generating plant of high efficiency utilizes a conventional steam plant powered by a fossil fuel such as coal, gas or oil, in internal integration with a high temperature solid-oxide fuel-cell. In one embodiment, the spent fuel and the wast heat from the fuel-cell of electrochemical action is made directly available to the combustion furnace of the steam plant for thermodynamic extraction. The system can achieve efficiencies up to 65% compared to ordinary steam plants which have an efficiency of about 35%.
