Patent number: 9528189Abstract: A gas generating device for generating an oxygen gas and/or a hydrogen gas from an electrolytic solution containing water, including an anode electrode, a cathode electrode, a plurality of through holes and a gas containing unit. The anode electrode (photocatalyst supporting electrode) has a photocatalyst-containing layer containing a photocatalyst producing an oxygen gas from the electrolytic solution by a photocatalytic reaction. The cathode electrode produces a hydrogen gas from electrons and hydrogen ions that are generated in the electrolytic solution by the photocatalytic reaction at the photocatalyst-containing layer. The through holes are formed on at least one of the anode electrode and the cathode electrode, and the through holes allow the produced oxygen gas or hydrogen gas to pass therethrough, but do not allow the electrolytic solution to pass therethrough. The gas containing unit holds the oxygen gas or hydrogen gas that has passed through the through holes.Type: GrantFiled: September 8, 2010Date of Patent: December 27, 2016Assignee: MITSUI CHEMICALS, INC.Inventors: Keiji Ueno, Mitsuru Sadamoto, Hiroko Wachi, Hiroshi Maekawa
