It is electric between electrode under the conditions of constant Faradaic current between a cathode and an anode there are electrical potential difference in water electrolysis process
Potential difference is smaller, and it is fewer to obtain the electric energy that unit volume gas-phase product is consumed.Conversely, electrolysis energy consumption is higher.Electrical potential difference between electrode
It is made of three parts：Electrolyte ohm voltage drop, amberplex voltage drop, electrode overpotential.When having in electrode surface and nearby
When gas-phase product adheres to or assembles, since the weak bubble of electric conductivity exists, electrode overpotential and electrolyte ohm can be caused at the same time
The rise of pressure drop, and then electrical potential difference between electrode is increased, increase electrolysis energy consumption (Mingyong Wang, Zhi Wang, Xuzhong
Gong,Zhancheng Guo.The intensification technologies to water electrolysis for
hydrogen production–A review[J].Renewable and Sustainable Energy Reviews,
2014,29:573–588.)。
In existing directly water electrolytic oxygen generating/hydrogen manufacturing, generally electrolyte flow is forced by gravity or by circulating pump
Drive away gas-phase product.But under such as space station microgravity environment, since gravity disappears, buoyancy is almost in a liquid for oxygen bubbles
It is zero, bubble is difficult to be desorbed after electrode surface nucleation, a large amount of aggregations of the gas-phase product in electrode surface is caused, so as to add
Electrolysis energy consumption.And the pump driving electrolyte circulation of electric energy input is relied on, extra power consumption undoubtedly is needed again, is unfavorable for being electrolysed
The reduction of comprehensive energy consumption.

The invention will be further described with reference to the accompanying drawings and examples, but should not be construed the above-mentioned theme of the present invention
Scope is only limitted to following embodiments.Without departing from the idea case in the present invention described above, known according to ordinary skill
Knowledge and customary means, make various replacements and change, should all include within the scope of the present invention.
Referring to Fig. 1 and Fig. 2, the present embodiment provides a kind of device of microgravity field drives intensified electrolysis water oxygen/hydrogen manufacturing,
Including electrolysis groove body 1, oxygen collector 2, hydrogen collecting apparatus 3, external magnets 4 and power supply.
Anode-side electrolyte outlet 5, cathode side electrolyte outlet 6 and electrolysis are provided with the electrolysis groove body 1
Liquid import 7.The electrolysis groove body 1 is discoid groove body.The electrolyte inlet 7 is arranged on the vertical of electrolysis groove body 1
On center line.The anode-side electrolyte outlet 5 and cathode side electrolyte outlet 6 are separately positioned on electrolysis groove body 1
Circumference side, and on its central symmetry.Wherein described anode-side electrolyte outlet 5 and cathode side electrolyte outlet 6
Towards on the contrary, their runner is parallel to each other.
The anode-side electrolyte outlet 5 is provided with oxygen collector 2.The cathode side electrolyte outlet 6 is installed
There are hydrogen collecting apparatus 3.
The yin, yang electrode of the power supply is arranged symmetrically in the inner wall both sides of electrolysis groove body 1.Its Anodic 8 is close to anode
Side electrolyte outlet 5, cathode 9 is close to cathode side electrolyte outlet 6.
The external magnets 4 include the identical permanent magnet of four block sizes, and every two pieces of permanent magnets are one group, are divided into A groups and B
Group.Two pieces of permanent magnets of A groups are symmetrically mounted on electrolysis groove body 1 close to the upper and lower surface of 8 side of anode, and N, S are extremely opposite；B
Two pieces of permanent magnets of group are symmetrically mounted on electrolysis groove body 1 close to the upper and lower surface of 9 side of cathode, while S, N are extremely opposite；Its
The magnetic pole reverse arrangement of middle two groups of permanent magnets of A, B so that in groove body 1 is electrolysed, by anode to cathode side, form direction phase
Anti- non-uniform magnetic-field, as shown in Figure 3.Between electrode after current turns ON so that close to anode side and close cathode side shape
Into Lorentz force direction it is opposite.The inside of the electrolysis groove body 1 is additionally provided with two pieces of deflectors 10.This two pieces of deflectors 10
Respectively close to anode-side electrolyte outlet 5 and cathode side electrolyte outlet 6.
Since there are external magnets 4, the Lorentz force that electromagnetic field produces is applied on fluid in the form of body force, long-range navigation
Hereby the size and Orientation of power is related with electric current (j) and local magnetic induction intensity (B)：F=j × B.Due to the magnetic field at yin, yang the two poles of the earth
Direction is on the contrary, the opposite Lorentz force in direction can be formed, so as to realize electrolyte around the vertical center of electrolysis groove body 1
The flowing of line (Z-direction).The electrolyte for being mixed with gas-phase product goes out by two of inertial flow from close cathode and anode
Mouth excludes, and the gas collector of corresponding exit position arrangement is collected into hydrogen and oxygen respectively.By rotational flow institute shape
Into the central area negative pressure of electrolysis groove body 1 necessarily cause electrolyte to be automatically replenished from electrolyte inlet 7, without extra conveying
Pressure.
To prevent gas-phase product from mutually mixing and improving product purity, close to two outlets (anode-side electrolyte discharge
Mouth 5 and cathode side electrolyte outlet 6) position, it is respectively arranged one piece of deflector 10.Need what is illustrated, permanent magnet of the invention
Arrangement depending on the direction of the position of electrode and electrolyte outlet, its principle seek to ensure anode-side formed long-range navigation
Hereby power is identical with the direction of anode-side electrolyte outlet 5, the Lorentz force that cathode side is formed and cathode side electrolyte outlet 6
Direction it is identical, so contribute to the exclusion of electrolyte and gas-phase product.
Specifically, in electrolysis, it is electrolysed in groove body 1 and is full of electrolyte.After power on, as the progress of electrolysis is in the moon
Pole 9 and the surface of anode 8 separate out hydrogen and oxygen respectively.The non-uniform magnetic-field that space is formed causes around cathode 9 and anode 8
Lorentz force direction is on the contrary, so electrolyte is driven by Lorentz force does rotational flow in electrolysis groove body 1.In deflector 10
Under the action of, hydrogen and oxygen are excluded with rotary motion and from each outlet with electrolyte, in the gas collection close to exit
It is collected in device, electrolyte outflow is in case recycle.Deflector 10 can effectively prevent due to rotary motion and caused by
The mixing of hydrogen and oxygen, can control the purity of gaseous product well.The present invention builds external magnetic field using permanent magnet at the same time,
External magnetic field strength is fixed.Size by adjusting electric current can control the generating rate and electrolyte flow speed of gas-phase product
Degree.
