FIELD: power industry.SUBSTANCE: invention relates to electrochemical generators, in which chemical energy of fuel is converted directly to electric energy, and namely to high-temperature electrochemical devices with internal fuel conversion. The invention describes a manufacturing method of a high-temperature electrochemical device converting chemical fuel energy to electricity and heat at one stage, with removal of some part of conversion products in the form of a high-temperature fuel element with internal catalytic conversion. A protonic carrier of the fuel element is activated by a complex multifrequency superhigh-frequency generator till the state of formation of flat proton-carrying plasma on frequencies adjacent to resonances of a grid so that continuous sintering of ceramics of a protonic membrane is performed during operation with elimination of structural defects, which contributes to recovery of the structure of the protonic membrane and a number of qualitative parameters, which generally determines parameters of the whole device that is structurally made uniformly in the form of a superhigh-frequency waveguide reactor system converting energy of hydrocarbon raw material by air oxidation.EFFECT: increasing efficiency and specific performance of high-temperature fuel elements owing to increasing protonic conductivity of a separating membrane; overall increase of fuel use efficiency due to endothermic carbon-dioxide reforming and possibility of synthesis gas reservation; increase of safety of reactors using methane; overall reduction of capital investments per unit of produced energy; increase of service life of an item owing to eliminating destructive factors typical of similar technical items.3 cl, 6 dwg |
