WATER TREATMENT SYSTEM USING ALKALINE WATER ELECTROLYSIS DEVICE AND ALKALINE FUEL CELL

Document Type and Number:

WIPO Patent Application WO/2016/204233

Kind Code:

A1

Abstract:

Provided is a water treatment system using an alkaline water electrolysis device and an alkaline fuel cell that, by continuing electrolysis treatment: efficiently circulate and use, in the water treatment system, the hydrogen gas, oxygen gas, water in an amount corresponding to the water feedstock that disappears as a result of the electrolysis, and electrolyte solution that are necessary in the alkaline water electrolysis device and the alkaline fuel cell; and significantly reduce the electric power used. The present invention is a water treatment system using an alkaline water electrolysis device and an alkaline fuel cell, wherein: the alkaline water electrolysis device and alkaline fuel cell are linked; the volume of the water feedstock is reduced by the alkaline water electrolysis device; the oxygen gas and hydrogen gas generated from the alkaline water electrolysis device are supplied to the alkaline fuel cell; power is generated by the alkaline fuel cell using the oxygen gas and hydrogen gas; electric energy and water are collected; and the collected electric energy is supplied to the alkaline water electrolysis device as a power source therefor.
