Title:
HYDROGEN GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/203857
Kind Code:
A1
Abstract:
A hydrogen generation system 40 is provided with: an electrolysis vessel 12 in which hydrogen is generated by the electrolysis of water; a direct-current power supply 14 which can supply an electrolytic current to the electrolysis vessel 12 by utilizing, as a direct current, an electric power sourced from a renewable energy input from an electric power generation device capable of generating an electric power sourced from a renewable energy; and a reverse current inhibition section 34 which can inhibit a reverse current I' generated in the electrolysis vessel 12 when the generation of an electric power sourced from the renewable energy is halted. The electrolysis vessel 12 is equipped with an electrode for oxygen generation use, an electrode for hydrogen generation use, and a solid polymer electrolyte membrane arranged between the electrode for oxygen generation use and the electrode for hydrogen generation use. The reverse current inhibition section 34 is arranged on a pathway through which the reverse current I' can flow.
