HIGH CONCENTRATION HYDROGEN GAS SUPPLY APPARATUS FOR LIVING MATTER

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen gas supply apparatus for a living matter in which hydrogen gas beneficial in health can be safely used in a field of medical care and household.SOLUTION: A hydrogen gas supply apparatus for a living matter includes: an electrolysis tank 1 that includes an electrolytic chamber 11 in which a raw water to be electrolyzed 12 is introduced, at least one barrier membrane 13 that blocks an inside and an outside of the electrolytic chamber, and at least one pair of electrode plates 14, 15 disposed respectively in the inside and the outside of the electrolytic chamber to pinch the barrier membrane, and in which an electrode plate of the outside of the electrolytic chamber is disposed to contact the barrier membrane; a direct current power source 2 that applies direct current voltage to the pair of electrode plates; and a dilution gas feeder 3 that dilutes hydrogen gas generated from an electrode plate becoming a cathode, wherein dilution gas supplied from the dilution gas feeder is ventilated to the cathode or the cathode water surface, thereby hydrogen gas concentration of the cathode vicinity at electrolysis is maintained at any time less than 18.3 vol.%, and a mixed gas including hydrogen gas and dilution gas in which hydrogen gas concentration is 4-18.3 vol.% is supplied to a living matter.
