Patent attributes
An electrolytic cell 1 comprises electrolysis chambers 5 and 6 arranged opposite to each other through a diaphragm 11, raw water feed means 8 and 7, electrodes 12a and 12b arranged in the electrolysis chambers 5 and 6 in a manner sandwiching the diaphragm 11, and electrolyzed water take-out means 9 and 10 for taking out electrolyzed water obtained by electrolyzing raw water. The electrolytic cell 1 comprises a membrane-electrode assembly 2 formed so as to cause the electrodes 12a and 12b to respectively adhere to both surfaces of the diaphragm 11, mesh current collectors 13 and 14 respectively arranged opposite to the electrodes 12a and 12b, and a plurality of protrusions 15 and 16. The electrolytic cell 1 comprises connecting members 17 and 18 connecting the mesh current collectors 13 and 14 to an external electric power supply in a manner penetrating the outer walls of the electrolysis chambers 5 and 6, and resilient members 25 for energetically pressing the connecting members 17 and 18 toward the mesh current collectors 13 and 14. The electrolytic cell 1 comprises a plurality of the protrusions 15 and 16, and the connecting members 17 and 18, respectively at positions opposite to each other on both sides of the membrane-electrode assembly 2. The current collectors 13 and 14 are formed of a corrosion resistant conductive material. The electrodes 12a and 12b are formed of a porous material containing a conductive powder.
