Publication number: 20170369339Abstract: Technologies are generally described for an apparatus configured to process a volume of a fluid and provide an electrolyzed fluid. Example apparatuses described herein may include a base cell, electrodes and/or a variable expansion cell. The base cell may be configured to contain at least a portion of the volume of the fluid. Electrodes may include an anode and a cathode. The electrodes may be configured to be mounted within the base cell. The variable expansion cell may be coupled to the base cell, and adjustably configured to change a volumetric space of the apparatus to accommodate the volume of the fluid such that the electrodes are substantially immersed in the fluid.Type: ApplicationFiled: June 22, 2016Publication date: December 28, 2017Applicant: OSAKA ELECTRO-COMMUNICATION UNIVERSITYInventors: Koichi Umimoto, Shunji Nagata, Aki Kamada

Patent number: 9115011Abstract: An electrolyzed water production apparatus and method safely and simply produce electrolyzed water having a sterilizing action, having a physiologically neutral pH value, and, in addition, simultaneously with strong acidic electrolyzed water and strong alkaline electrolyzed water depending upon the structure. The electrolyzed water production apparatus has an electrolyzer tank with an end that receives or stores raw water, and a power supply. The interior portion of the electrolyzer tank is partitioned by a plurality of diaphragms into a plurality of regions. An anode and a cathode (constituting an electrode pair) are positioned on either side of the diaphragm. In a certain region of the electrolyzer tank, an anode and a cathode are arranged so as to face each other without a diaphragm sandwiched between them. When raw water for electrolysis is electrolyzed, electrolyzed water having a desired pH of a neutral range is produced during electrolysis.Type: GrantFiled: May 8, 2012Date of Patent: August 25, 2015Assignee: OSAKA ELECTRO-COMMUNICATION UNIVERSITYInventors: Koichi Umimoto, Shunji Nagata
