INSTALLATION FOR PRODUCING HYDROGEN BY THERMOELECTRIC DECOMPOSITION OF WATER Russian patent published in 2024 - IPC C01B3/02 C25B1/04 B01J7/00 

FIELD: hydrogen energy.

SUBSTANCE: invention can be used to produce hydrogen and oxygen using the heat of high-potential heat sources. The installation contains a fuel cell battery, a power supply, control and regulation unit, a thermal control system for the fuel cell battery, a water tank, a water supply pump, heat supply pipes, a high-temperature electrolyser, and pipelines for supplying hydrogen and oxygen to consumers. The electrolyser is connected by pipelines of two circulation circuits of gas mixtures through a recuperative heat exchanger, an intermediate heat exchanger for cooling the electrolysis products and a heat exchanger for heating and evaporating water with the input of the fuel cell battery, and the output of the fuel cell battery is connected through circulation pumps to the input of the high-temperature electrolyser. The water reservoir is connected to the inlet of the high-temperature electrolyser through a water supply pump, a heat exchanger for heating and evaporating water and a water vapour reheater, the pipelines of the circulation circuits of gas mixtures at the inlet of the fuel cell battery are connected through a condenser-cooler for separating water with pipelines for supplying hydrogen and oxygen to consumers, and the condenser cooler is connected to the water tank. The fuel cell battery, the intermediate heat exchanger for cooling the electrolysis products and the condenser-cooler are equipped with thermal control and heat removal systems. The high-temperature electrolyser and the steam reheater are connected by heat pipes to a source of high-grade heat.

EFFECT: increase in the energy efficiency of converting high-potential heat into hydrogen and oxygen, high purity of the resulting products and the environmental safety of their production.
