Abstract:
1. An electrolytic cell for electrolyzed water generator, comprising: a pair of electrolysis chambers arranged opposite to each other through an ion permeable diaphragm; raw water feed means for providing water containing no electrolyte as raw water to one of the electrolysis chambers and providing electrolyte-containing raw water to another of the electrolysis chambers; a pair of electrodes respectively arranged in the electrolysis chambers in a manner sandwiching the diaphragm; and electrolyzed water take-out means for taking out electrolyzed water obtained by electrolyzing the raw water fed into each of the electrolysis chambers through the raw water feed means by applying a voltage to both electrodes, from each of the electrolysis chambers; the electrolytic cell comprising: a membrane-electrode assembly formed with each of the electrodes adhered to each surface of the diaphragm; mesh current collectors arranged respectively opposite to the electrodes of the membrane-electrode assembly; and a plurality of protrusions that are respectively arranged on the inner walls of the electrolysis chambers at positions opposite each other on both sides of the membrane-electrode assembly, wherein each of the plurality of protrusions are in direct contact with the mesh current collectors and press the mesh current collectors toward the electrodes so as to bring the mesh current collectors into pressure contact with the electrodes in order to obtain a pressing strength to supply sufficient electric power from the current collectors to the electrodes for electrolyzing by enlarging the contact area of the mesh current collectors and the electrodes.
