POWER PLANT BASED ON A FUEL CELL, HYDROCARBON TO HYDROCARBON CONVERTER AND OXYGEN CONCENTRATOR Russian patent published in 2021 - IPC H01M8/10 H01M8/04 

FIELD: fuel cells.

SUBSTANCE: invention relates to fuel cells, in particular to power generating units on fuel cells, intended for use as mobile (portable, mobile) and/or stationary units, including periodically operating in airless environments, for example, in marine underwater robotic systems. To achieve the effect, a power plant based on a fuel cell, a hydrocarbon-to-hydrogen converter and an oxygen concentrator is proposed, including a fuel cell, a hydrocarbon fuel converter, storage tanks for water, hydrogen and oxygen, connected by pipelines with electrovalves and throttles, while the power plant contains an oxygen concentrator, including an air compressor, columns with zeolite, solenoid valves and throttles, in which a mixture highly enriched with oxygen is produced, which is partially accumulated in the oxygen tank and is fed through the pipeline both to the inlet of the oxidation circuit of the fuel cell and to the inlet of the hydrocarbon fuel converter, which includes a high-temperature catalytic unit connected by a pipeline to a reservoir with hydrocarbon fuel, in which a gas mixture of carbon dioxide and hydrogen is formed, a heat exchanger in which it is cooled, and a reactor for steam reforming of carbon monoxide, connected by a pipeline with a tank with water, while the produced mixture of hydrogen and carbon dioxide flows through the pipeline into a membrane metal hydrogen separator, from which the produced hydrogen is supplied through the pipeline to both the hydrogen storage tank and the hydrogen inlet. the fuel cell circuit.

EFFECT: ensuring the operation of fuel cells and a hydrocarbon fuel converter using oxygen of a high degree of enrichment with a simplified design of the installation and an increase in its operation time in airless environments.
