APPARATUS AND METHOD FOR HYDROGEN PRODUCTION USING HIGH-TEMPERATURE WATER VAPOR ELECTROLYSIS

摘要

An hydrogen production system capable of realizing high hydrogen manufacture efficiency and of stable operation control even if electric power to be supplied to an electrolysis cell is fluctuated.;A hydrogen production system 10 includes a selection unit 50 for selecting the electrolysis cell 11 to which electric power is supplied in accordance with fluctuation of electric power supplied to the electrolysis cell 11, a first heat control unit 51 for holding a temperature of the electrolysis cell 11 at a predetermined temperature by using a heater 13 provided inside a reaction vessel 12, a first flow rate control unit 41 for adjusting a flow rate of water to be supplied to the steam generator 14 and holding a flow rate of high temperature steam to be inputted into the electrolysis cell 11 constant, and a second flow rate control unit 42 for adjusting a flow rate of a supplied hydrogen storage material in accordance with the fluctuation of electric power.
