METHOD FOR CONTROLLING SALT WATER ELECTROLYTIC CELL USING FUEL CELL

摘要

PROBLEM TO BE SOLVED: To properly control operatable electric current range of a fuel cell and to control the fuel cell so that sodium hypochlorite being a product may be formed in a stable concentration even if the current quantity of an electrolytic cell is changed by the variation of voltage in the case when a sodium hypochlorite solution is formed by a salt water electrolytic cell using a fuel cell. SOLUTION: In the control method of the electrolytic cell for forming the sodium hypochlorite solution by electrolyzing salt water and using the fuel cell as power source, the fuel cell is connected to the electrolytic cell through a power changing device for controlling the voltage, and at the point of time at which the electrolytic cell is started by connecting the fuel cell to the electrolytic cell, after gradually rising the voltage of the electrolytic cell to the voltage of the fuel cell by the power changing device, the electrolytic cell is continuously operated steadily through the power changing device.
