Abstract

A novel hydrogen production method uses low power input for decomposing water so as to produce hydrogen. The invention utilizes the principle of electrolysis, maintains the ionic orientating distribution in two types of solution and polarization of an inert metal C by the action of an applied electric field, causes the anion and cation of the solution to be directionally distributed in two cavities, namely a and b by driving a stirring apparatus to rotate by an external force, and respectively extracts an hydroxyl ion and a hydrogen ion for maintaining continuous electrolysis. The invention has the advantages of easy realization, simple structure, low cost, and wide application, and can be used in the low-density energy hydrogen production fields such as waste heat recovery and solar energy hydrogen production, and the like, especially when combining the technology of Patent No. ZL 200620024138.6.

Description

New hydrogen production method

Technical field

The present invention relates to a kind of new hydrogen production method, particularly utilize the method for electrolysis principle low power hydrogen manufacturing.

Background technology

Hydrogen is a kind of secondary energy, also is a kind of industrial chemicals, is used for every profession and trades such as synthetic ammonia, chemical industry, papermaking, environment protection, electronics, food, medicine, weaving, mining industry, agricultural waste processing in a large number.Hydrogen is the future ideality clean energy in addition, especially various resources be about to exhausted in, and pollution-free, good characteristics such as fuel value height.But on the earth most hydrogen be form with compound exist (the most general form is a water---H2O), and the decomposition voltage of water is 1.23V (reaching 2.3V because overpotential exists), but under lower powered situation, existing generator does not reach this decomposition voltage under low power density, so can not be with water decomposition, therefore how hydrogen can be extracted from water under lower powered situation is the hydrogen manufacturing key issue.

The objective of the invention is in extraneous low energy source density water of decomposition and produce hydrogen.Particularly can be applied in fields such as waste heat recovery and solar hydrogen making in conjunction with patent No. ZL 200620024138.6.

Summary of the invention

The present invention utilizes the brine electrolysis principle, by the extra electric field effect, has kept the directed branch and the middle inert metal C of polarization of two effects of ion, utilizes the external force acting to come " taking-up " hydroxide ion and hydrogen ion respectively, keeps electrolysis voltage and keeps electrolysis lasting.

Address this problem, reach the decomposition voltage of water when importing with low power kinetic energy, just realize low power hydrogen manufacturing purpose in the external world.

Description of drawings

Fig. 1 is ultimate principle figure, and wherein A, B are two metal inertia pole plates, is immersed in respectively in two each apparent positive polarities and the electronegative solution, and keeps two-plate voltage, and be connected with lead.

Fig. 2 is equivalent working drawing (vertical view), and wherein A1, B1 are two metal inertia pole plates, and provides constant voltage with power supply.Interior outer chamber wall is an insulating material, and middle C is the inert metal body, the liquid in the chamber can be contacted with inert metal, and do not contact with extraneous electrode, and the dispatch from foreign news agency field energy is passed the outer layer insulation wall and acted on a, the liquid in the b chamber.1,2,3,4 is the stirring sheet of stirrer, can be under the effect of external force, and directed the rotation.Liquid in the cavity is salts solution (Na ₂SO ₄Deng the salt of zwitterion discharge capability a little less than) than hydrogen ion and hydroxide radical.

Embodiment

One, ultimate principle

As Fig. 1: it is equivalent to the brine electrolysis process.

During brine electrolysis, under certain voltage, cathodic area and positive column are because the effect of internal electric field contains a large amount of positively charged ions and negatively charged ion respectively, along with the carrying out of brine electrolysis, the cathodic area can generate hydroxide ion, and the positive column can generate hydrogen ion, if separate with baffle plate in the middle of the solution this moment, then electrolysis phenomenon can be ended, because become the loop inadequately this moment, that is to say that hydrogen ion and hydroxide ion can not directedly move.But if, then be equivalent to baffle plate is taken away, so the electrolysis meeting is proceeded with each hydroxide ion that generates of the negative and positive the two poles of the earth under the present situation and hydrogen ion respectively continuous " taking-up ".

If come substitute electric power that voltage is provided with the metal that is placed on the electric field the inside, and can keep the potential difference between two solution, then the electrolysis meeting continues, must keep the concentration of amount of substance of the zwitterion in two solution constant and keep this potential difference, and both are conflicting, thereby for addressing this problem key of the present invention just.

Two, principle of work

As Fig. 2: cavity a, be equipped with Na in the b ₂SO ₄(the present invention is with Na for strong solution ₂SO ₄Strong solution is a working medium), because adding the highfield effect makes a, directed moving takes place in the zwitterion in the strong solution in b two chambeies, and intermediary inert metal C is also polarized, make near the side anion concentration of A (positive pole) bigger, and away from a side (near the side of C) cation concn bigger, so the positively charged ion of the overwhelming majority all is in a of chamber, in like manner in the b of chamber a large amount of negatively charged ion is arranged, so the effect of the inert metal body that the mediates metal electrode in will similar Fig. 1 (a side polyelectrons and opposite side electron deficiency), work as a, when the liquid electromotive force in b two chambeies reaches the decomposition voltage of water with the C both sides respectively, the brine electrolysis phenomenon will take place.

But this moment, electrolysis can not continue as separating with baffle plate, had only hydroxide ion and hydrogen ion difference " taking-up ", and electrolysis just can continue.

And the effect of stirring sheet 1,2,3,4 is exactly to take out hydroxide ion and hydrogen ion, keeps zwitterion concentration and electrolytic prerequisite in two chambeies, keeps continuing electrolytic effect thereby reach, and its concrete working process is as follows:

Under the effect of external force, 1,2,3,4 can synperiodic orientation rotate, when 1 rotates in last narrow district, high efficiency promotion liquid rotates, when 1 turns over a chamber, because the viscosity of liquid, meeting eddy generation phenomenon (clockwise rotating) in a chamber, close metallic object one side is owing to hydrogen ion discharge in a chamber, and the hydroxide radical that stays equivalent reduces electromotive force, but rotate under the effect that forms eddy current in external electric field and stirrer, hydroxide radical can move to the left, at first can neutralize with the hydrogen ion that is come by 1 promotion, and then unnecessary hydroxide radical reaches a chamber left side edge, then can be pushed in the b chamber, thereby reach the purpose of taking out hydroxide ion.Hydroxide radical is at first neutralized by hydrogen ion when should 1 turning to the b chamber, and same purpose mechanism takes place.Other stirring sheet also can same purpose, so the water electrolysis hydrogen production that can continue under certain outer reactive force.

Wherein the positively charged ion that brings along with stirring sheet also has sodium ion, and negatively charged ion also has sulfate ion etc., because the effect positively charged ion of external electric field and eddy current can be retained in a chamber, negatively charged ion can be pulled in the b chamber.Equally, negatively charged ion can be retained in the b chamber.
