Technical field

A kind of pure water hydrogen and oxygen electrolyzing manufacturing machine, for for producing hydrogen and oxygen.

Background technology

Most hydrogen is all present in the forms such as water and organic compound on the earth, and hydrogen is a kind of colourless, odorless, nothing The nonmetallic gas of taste, and it is easy to collection again because not having toxicity and radioactivity, or even high-energy can be produced, and it is anti-with oxygen element Should so that have wide range of applications, including chemistry, physics, even engineering science, physiology etc., especially medically, ground according to part Study carefully prompting, hydrogen can produce reaction bonded with hydroxy radical, the residual of internal hydroxy radical thereby be reduced, again it is desirable that hydrogen The strong anti-oxidation power that molecule possesses, can develop more benefit materials.

And the mode for obtaining hydrogen includes heat chemistry, water-gas, water electrolysis, steam restructuring etc. and may achieve, it will especially steam Hydrogen yield when gas recombination method is used for natural gas is a kind of method on the largest scale.When vapor and methane high temperature about 1000- When 1400K reacts, carbon monoxide and hydrogen can be produced, in this reaction, relatively low pressure is bestowed to course of reaction on the contrary Efficiency can more be more than high pressure, but must be carried out under high pressure for fear of hydrogen purification system, to shorten the time so that course of reaction Equally using high pressure by the way of, however, but also therefore limit output efficiency, on the other hand, due to needed during output pressurization add Temperature, even if the mode for being adjusted by pressure shortens processing time, but the amplitude shortened is still limited, and hydrogen molecule is at high temperature Hydrogen atom is easily dissociated into, the big hydrogen atom of activity will likely produce reaction with other elements, therefore hydrogen purity will be caused to beat greatly Discount, furthermore, it is careless slightly in the case of mass storage also because hydrogen activity is big, i.e., it can cause peace event of endangering.

Another common method is water electrolysis method, adds water to electrolyte formation solion, and logical with a pair of electrodes Enter direct current to be electrolysed, hydrogen and oxygen are produced via redox reaction, but which is because must be added to electrolyte ability Make water decomposition, be especially usually to add strong acid or highly basic as electrolyte, so the hydrogen purity produced still has doubt.

As PEM comes out, water electrolysis may not necessarily rely on the addition of electrolyte again, but directly by pure water electricity Solution, as shown in figure 5, there is an apparatus for electrolyzing 9, pure water enters reaction chamber 92 by anode-side, reaction chamber 92 in addition to an electrode, The anode diffusion layer and anode catalyst layer of stainless (steel) wire are additionally provided with, it is conductive and anode catalyst layer by stainless (steel) wire Effect, pure water dissociates as oxonium ion and hydrogen ion herein, oxonium ion then guide be connected to anode stainless (steel) wire release electronics and As oxygen discharge；Hydrogen ion and water can penetrate the PEM in reaction chamber 92, further touch cathode catalysis Oxidant layer, and rear the cathode diffusion layer that is constituted of carbon paper or carbon cloth, hydrogen ion leads via carbon paper or carbon cloth Electrical and permeability, reception is reduced into hydrogen discharge via the electronics that negative electrode is provided.

Wherein, because the inoxidizability of carbon fiber is extremely low, therefore it is only capable of not using in anode-side as cathode diffusion layer； Though the tensile strength of another aspect carbon fiber is big, bend resistance effect is poor, it is impossible to bear lateral larger pressure；Especially carbon is fine Wei Bu is that, to weave shaping, thickness can not arbitrarily increase, and also further limits the thickness of cathode diffusion layer, with regard to this influence hydrogen ion Useful effect region between cathode diffusion layer.

Therefore, how to increase the useful effect region between hydrogen ion and cathode diffusion layer, lift the production capacity of hydrogen, and Allow anode diffusion layer and cathode diffusion layer to use identical material-structure, the diffusion layer of both sides arbitrarily can be exchanged mutually, does not have There is the risk of assembly defect, also reduce cost of getting the raw materials ready, and bear lateral pressure conversion, be exactly this case focus to be improved.

Another object of the present utility model, be to provide it is a kind of with diffusion metal level as negative electrode and anode diffusion layer Pure water hydrogen and oxygen electrolyzing manufacturing machine, because the ductility for spreading metal level is good, can bear after a large amount of generations of gas, chamber interior Pressure increase, to lift reliability and extend warranty cycle.

A further object of the present utility model, is to provide a kind of with pure water electrolysis hydrogen of the diffusion metal level as diffusion layer Oxygen manufacturing machine, by increase thickness of diffusion layer, is substantially improved hydrogen production efficiency.

A kind of pure water hydrogen and oxygen electrolyzing manufacturing machine disclosed in this case, including：One electrolysis unit and a sealing contain body, by Sealing contains the water injection hole injection pure water on body, is diffused to via anode metal layer after one layer of oxidation catalyst layer, pure water receives The electric energy of electrode supply is dissociated, and isolates oxygen with hydrogen ion by PEM, and hydrogen ion meets reducing catalyst layer It is reduced into after hydrogen and passes through by cathode metal layer, negative electrode, is finally discharged by hydrogen blistering, in addition, oxygen is then via anode metal layer, sun Pole, is finally discharged by oxygen outlet.
