    摘要: A water electrolysis stack in which a water electrolysis cell is laminated, a water supply side path for supplying water to the water electrolysis stack, and a hydrogen side path for recovering hydrogen generated from the water electrolysis stack are provided, and the water supply side path includes a pump which is a power source for supplying water to the water electrolysis stack, an ion exchanger arranged between the pump and the water electrolysis stack, a bypass which is a path for flowing water from the pump to the water electrolysis stack without passing through the ion exchanger, a valve for adjusting an amount of water flowing to the bypass, and a controller for adjusting a valve.

    摘要: Power is provided to an electrochemical cell. The electrochemical cell includes an anode side and a cathode side. Hydrogen sulfide in a liquid state is flowed to the anode side. An operating temperature and an operating pressure are maintained within the anode side, such that the hydrogen sulfide in the anode side is at a supercritical state. Providing power to the electrochemical cell facilitates electrolysis of the hydrogen sulfide to produce sulfur and protons on the anode side. Providing power to the electrochemical cell facilitates reduction of protons to produce hydrogen on the cathode side. A membrane separating the anode side from the cathode side prevents flow of hydrogen sulfide and sulfur from passing through the membrane while allowing hydrogen cations to pass through the membrane. Sulfur is flowed out of the anode side. Hydrogen is flowed out of the cathode side.
