Selective hydrogen adding equipment for living organism applicable fluid

A selective hydrogen adding equipment for supplying hydrogen to a living organism applicable fluid, comprising:

• a hydrogen generating system that contains a hydrogen generating agent as an essential component;
• a hydrogen bubble forming implement that stores the hydrogen generating system and has a gas/liquid separating section including a gas-permeable film or an open-close valve;
• and
• a closed container to accommodate the hydrogen adding equipment,
• wherein the gas/liquid separating section is configured to vent hydrogen gas generated by a contact reaction between the hydrogen generating system and a generating-purpose water from an interior of the hydrogen bubble forming implement to an exterior thereof, and the gas/liquid separating section is configured to avoid the generating-purpose water from flowing out from the interior of the hydrogen bubble forming implement to the exterior thereof,
• wherein a living organism applicable hydrogen-contained fluid is obtained through causing the hydrogen generating system and the generating-purpose water to react in the hydrogen bubble forming implement and supplying hydrogen gas generated in the hydrogen bubble forming implement into the living organism applicable fluid via the gas/liquid separating section,
• wherein the hydrogen generating agent comprises a metal raw material including a hydrogenated metal or a metal having a higher ionization tendency than hydrogen, and the metal raw material is such that the temperature thereof is below 50 degrees C. or requires 5 seconds or more before reaching 50 degrees C. when measured by a metal raw material heat generation temperature measurement method, whereby the reaction heat due to hydrogen generating reaction is suppressed from directly transferring to the gas-permeable film or the open-close valve of the gas/liquid separating section,
• and wherein the metal raw material heat generation temperature measurement method comprises reacting 500 mg of the metal raw material and 500 mg of malic acid (or 500 mg of aluminum potassium sulfate when the metal raw material comprises aluminum) in a tube with 500 mg of tap water at a water temperature 25 to 26 degrees C., and measuring the temperature of the metal raw material.
