Abstract: A process for the continuous conversion of energy chemically bound in a starting fuel based on C-H compounds into usable mechanical energy. For this purpose, a gas turbine is used and in order to obtain high mechanical efficiency the combustion is effected at least partially with a fuel obtained from the starting fuel by endothermic reaction, the heating of the reaction space for the endothermic reaction being effected either by compressed combustion air, which has been heated by the exhaust gases, or by the hot exhaust gas itself.

Abstract: The invention relates to a process for the combined generation of electrical and mechanical energy from the oxidation of fuel. In particular a hydrogen-containing gas is generated by endothermic reaction of hydrocarbon compounds, in which a portion of the hydrogen-containing gas is burned for generating a combustion gas. An oxygen-containing gas is then compressed and introduced into the combustion stage, and the energy is generated by expanding the hot combustion gas in at least one gas turbine. Further, the expanded combustion gas is used for indirect heating of the endothermic reaction. According to the present invention, at least a part of the generated hydrogen-containing gas is to be guided as anode gas through a fuel cell system for generating electrical energy and the anode exhaust gas is used for generating the combustion gas.
