(DE4032993-C)      The power generation plant has an electrical generator (G) driven by a gas turbine (T) that is also connected to a pair of air compressors (K1,K2). The compressor output passes through an indirectly heated exchanger (W) to a burner (B) that utilises on the containing gas, e.g. natural gas.    The exhaust from the turbine is used in a vapour reforming unit (R) that receives a mixture of gas and vapour. The output from the reformer passes to a fuel cell (FC) via the heat exchanger handling the fuel gas (15).    ADVANTAGE -   Improved efficiency of energy utilisation.    (JP6504873-W)      Method, and associated plant, for the combined generation of electrical and mechanical energy from the oxidn. of fuel is claimed.    Method comprises prodn. of a gas contg. H2 by the endothermic reaction of hydrocarbon cpds.; burning part of this gas to produce a combustion gas; compression and heating of an O2-contg. gas and feeding it into the combustion stage(s). At least part of the H2-contg. gas produced in the endothermic reaction is, in the prodn. of electrical energy, fed as anode gas through a fuel cell system, from which an anode exhaust gas contg. a residue of H2 is used for producing a combustion gas of increased pressure.    USE/ADVANTAGE -   The system enables the chemically compounded energy in a fuel to be converted into electrical and mechanical energy with an efficiency of at least 60% and possibly over 65%.    (US5417051-A)      The combined generation of electrical and mechanical energy from the oxidation of fuel comprises (a) generating a hydrogen-contg. gas by endothermic reaction of hydrocarbon cpds. in at least one stage with indirect heating of the endothermic reaction, (b) guiding at least a portion of the gas generated through a fuel cell system, (c) introducing the anode gas exhausted from the fuel cell system contg. a residual H2-content into at least one combustion stage for generating a hot combustion gas at increased pressure, (d) compressing an O2-contg. gas, (e) introducing the O2-contg. gas into the combustion stage, (f) generating mechanical energy by partial expansion of the hot combustion gas in at least one turbine, (g) indirectly heating the endothermic reaction using at least a partial flow of the at least partial expansion of the hot gas, (h) supplying the mechanical energy for the compression of the O2-contg. gas, (i) heating the compressed O2-contg. gas by indirect heat exchange with the partially cooled combustion gas in the endothermic reaction, (j) generating the combustion gas having increased pressure with surplus O2, and (k) feeding the partially expanded conduction gas from the turbine to the fuel cell system as cathode gas after conveying heat to compressed O2-contg. gas.    ADVANTAGE -   High efficiency.    (RU2119700-C1)      Method, and associated plant, for the combined generation of electrical and mechanical energy from the oxidn. of fuel is claimed.
