A method for converting heat directly into electric power comprises high-temperature decomposition of a working body into components (fuel and oxidizer) in endothermic reaction-dissociation process at a maximum cycle temperature Тusing the heat Qof a “thermal reservoir-source”; using as the working body components,which are decomposed as result of electrolysis into two components (fuel and oxidizer), supplying components to fuel sell electrodes; converting the chemical energy of the working body components into electric power using electrochemical generation in process of exothermic reaction-recombination of fuel and oxidizer in said fuel cell at the minimum cycle temperature Тremoving heat effect of exothermic reaction-recombination (i.e. waste heat of Qcycle) from the fuel cell to the “thermal reservoir-source”, returning the working body from the fuel cell for the subsequent decomposition by means of a circulating pump, with the working body decomposes into components by means of carrying out high-temperature electrolyses at a maximum cycle temperature ТThe high-temperature electrolysis of the working body is carried out by using a part of electric power produced by low-temperature electrochemical generation in the fuel cell, and high potential heat Qof the “thermal reservoir-source” at a maximum cycle temperature ТThe working body is additionally heated to the maximum cycle temperature Тon a path from a low-temperature fuel element to a high-temperature electrolyzer by regenerating the heat of the electrolysis products in a countercurrent heat exchanger and partly – by high-potential heat of the “thermal reservoir-source” at a maximum cycle temperature Т |
