According to this con hydrogen generating Source, special attention has to be paid figuration, the hydrogen gas is mixed with a diluent gas Sup because the reaction of hydrogen generation is difficult to plied from the diluent gas supplier 7 or with a diluent gas stop after once starting. introduced by the vacuum pump 8 from outside the gas phase 0005 Problems to be solved by the present invention portion 4 in the hydrogen gas generator 3 via the hydrogen gas include providing an apparatus for Supplying high-concen permeable membrane 5.

In general, it is said that hydrogen reacts with oxy 1 with the water 2 for reaction transfers to the gas phase gen in the air to become detonating gas when the hydrogen portion 4 in the hydrogen gas generator 3. Here, when the concentration exceeds 4.7 vol%. However, an event that such hydrogen gas generator 3 is closed Such as by a cover to avoid detonating gas leads to actual ignition (deflagration) may diffusion of the hydrogen gas into the air, the hydrogen con occur in most situations at a concentration much higher than centration in the gas phase portion 4 increases as time passes 4.7 vol% which is said to be the explosion limit of hydrogen. and will exceed 18.3 vol% which is the lower limit of deto According to the applicants experiment, when the hydrogen nation of hydrogen gas. concentration exceeds 10 to 15 vol%, the detonation is offen 0016.

However, even though a high concentration of diffuses into the air immediately after being generated, a hydrogen is intended to be obtained, it may be inappropriate Sufficient amount of the hydrogen gas cannot be served to a to require a concentration of hydrogen gas higher than 18.3% living organism.

Therefore, the hydrogen gas generator 3 according reaction of hydrogen and oxygen causes a shock wave to to the present invention has a feature that apart or whole of the propagate as detonation around there. gas phase portion 4 in the hydrogen gas generator 3 is covered 0024. That is, according to the present invention, the by the hydrogen gas permeable membrane 5. According to hydrogen gas concentration in the gas phase portion 4 in the Such a configuration, only a part of the hydrogen gas in the gas hydrogen gas generator 3 may preferably be maintained at phase portion 4 in the hydrogen gas generator 3 can be dis lower than 18.3 vol%, more preferably lower than 15.0 vol%. charged outside the hydrogen gas generator 3 thereby to and further preferably lower than 4.7 vol%. constantly maintain the hydrogen gas concentration in the gas 0025 Similarly, the hydrogen gas concentration in the phase portion 4 in the hydrogen gas generator 3 within a safe vicinity of the hydrogen gas permeable membrane 5 of the range. Such a hydrogen gas permeable membrane 5 may hydrogen gas generator 3 may preferably be maintained at preferably be, but is not limited to, a gas membrane that is lowerthan 15.0 vol%, more preferably lowerthan 10.0 vol%. poorly-permeable or non-permeable for water but permeable and further preferably lower than 3.0 vol%. for hydrogen gas. 0026. It is also preferred that the apparatus 10 for supply 0.018. In particular, when a hydrogen generating agent is ing high-concentration hydrogen gas for a living organism used as the hydrogen generating source, the chemical reaction according to the present invention further comprises at least (reaction of hydrogen generation) is difficult to stop after one of a diluent gas Supplier 7 or a vacuum pump 8.

Therefore, if the Supply of the diluent gas is hydrogen gas in the gas phase portion 4 in the hydrogen gas stopped, there is a risk in the prior art that the hydrogen generator 3 is mixed with the diluent gas Supplied via the concentration automatically continues to increase to a dan diluent gas Supplier 7 and/or the vacuum pump 8 which may gerous range. Even when the hydrogen gas generator is in a be provided at any point along the path through which the state of being half opened rather than in a completely closed hydrogen gas is served to a living organism. Through this system, ifa Sufficient space is not ensured in the hydrogen gas operation, a flow volume can be ensured at which the hydro generator or inapartition that houses the hydrogen generating gen is more efficiently carried, and the mixed gas containing agent, the generated hydrogen gas cannot be sufficiently dis the hydrogen gas and the diluent gas can be Supplied to a

It is preferred that the supply of the diluent gas is 0033 For example, when the diluent gas is supplied at a started as soon as possible after the hydrogen generating flow volume of 5 L/min via the diluent gas supplier 7 and/or agent 1 is contacted with the water 2 for reaction, or started the vacuum pump 8, it is preferred that the hydrogen gas is prior to contact with the water 2 for reaction. maintained with a generation amount of 0.915 L/min (18.3% 0028.

Therefore, when continuous use for 120 minutes is refers to a concept that includes normal air and artificial air, expected, the total generation amount of hydrogen is 109.8 L. and examples thereof include medical gas of which the oxy (0.915 Lx120 min). Here, if sodium boron hydride is used as gen concentration is adjusted and other medical gases which the hydrogen generating agent, the reaction formula of contain medical components such as anesthetic component. sodium boron hydride and water is as follows: Examples of the diluent gas supplier 7 which supplies such diluent gas include an apparatus, such as an air pump, which Since 4 mol (89.6 L) of hydrogen gas are generated from 1 can blow the diluent gas. mol of sodium boron hydride, it is preferred that the sodium 0029. The above-described vicinity of the hydrogen gas boronhydride to be used is less than 1.225 mol (109.8 L--89.6 permeable membrane 5 of the hydrogen gas generator 3 refers L) or 46.3 g (37.83 g/molx 1.225 mol). to a concept that includes a position separated by 7 cm and 0034. In a similar manner, when metal magnesium is used preferably 3 cm from the hydrogen gas permeable membrane as substituted for sodium boronhydride, the reaction formula 5, and most preferably a position in contact with the above of of metal magnesium and water is as follows: the hydrogen gas permeable membrane 5. Generally, the hydrogen gas concentration can be understood to increase as the measurement point comes close to the hydrogen gas per Since 1 mol (22.4 L) of hydrogen gas is generated from 1 mol meable membrane 5. Therefore, when the hydrogen gas con of metal magnesium, it is preferred that the metal magnesium centration at a position separated by 7 cm from the hydrogen to be used is less than 4.9 mol (109.8 L-22.4 L) or 117.6 g (24 gas permeable membrane 5 is lower than 18.3 vol %, the g/molx4.9 mol).

hydrogen gas concentration at a closer range than 7 cm can be 0035. The above can be generalized such that a use amount deemed also to be lower than 18.3 vol%. Accordingly, if the of the hydrogen generating agent in the present invention is measurement at the above position is difficult due to the size preferably less than {(flow volume (L/min)x0.183xestimated of the apparatus 10 for Supplying high-concentration hydro time (min) of continuous use)+(Substance quantity (mol) of gen gas for a living organism or other reason, the measure hydrogen molecules generated from 1 mol of the hydrogen ment may be performed at a closer range than the above generating agent in a chemical reaction formula of the hydro position but at a position as close as possible to the above gen generating agent and waterx22.4) mol.
