Description
Technical field
Technical field
The present invention relates to a kind of water electrolyser non-contact resistance electrodes, belong to water electrolysis hydrogen producing technical field.
Background technology
Typical water electrolysis hydrogen producing electrolytic cell is in series by several tank houses, under high current, low voltage condition
Operation, electrode is the element of tank house.Electrode is made of electrode plate, supporter, electrode network, or is tied by band support
Electrode plate, the electrode network composition of structure.When electrode is passed through direct current and is electrolysed, the conduction of electric current is contact between these parts
Electrically conducting manner, therefore the contact resistance generated is unavoidable.
Water electrolyser is a load for having certain resistance value, and resistance value is bath resistance, bubble resistance, diaphragm
The sum of resistance, polarization resistance, contact resistance.The theoretical decomposition voltage of water is 1.23V, and electrolytic process must be higher than decomposition voltage
Under conditions of carry out, to meet the requirement of gas production, it is necessary to maintain specified current density, overcome the influence of electrolytic cell resistance
Certain voltage must be applied, therefore the power consumption of electrolytic cell unit gas production is larger.
There is contact resistance in electrode, the prior art is often connect by changing the means of electrode surface material to reduce between each other
The resistance value of electric shock resistance, however in use, due to impurity etc. in electrolyte, electrode surface material can be by impurity effect
Its original effect is lost, the resistance value of contact resistance between electrode is significantly increased instead, increases energy consumption.

Electric shock resistance electrode includes electrode plate assembly, electrode support and electrode network；The electrode plate assembly includes metal electrode frame and weldering
The main electrode plate being connected in the metal electrode frame, metal electrode frame both sides are equipped with annular convex platform, on the annular convex platform
It is welded with the electrode network, the electrode support is welded between the electrode network and the main electrode plate.
The improvement of above-mentioned technical proposal is：The metal electrode frame is carbon steel electrode frame, and the main electrode plate is cold rolling
Deep drawing sheet steel electrode plate.
The improvement of above-mentioned technical proposal is：The electrode support is sheet metal silk screen.
The improvement of above-mentioned technical proposal is：The electrode support is arranged several convex on the main electrode plate for array
It rises.
The improvement of above-mentioned technical proposal is：The electrode network is worked out by nickel or nickel alloy, and the electrode net surface applies
It is covered with nickel-aluminum alloy active coating.
The present invention is using the advantageous effect of above-mentioned technical proposal：By by main electrode plate, electrode support and electrode network
It is welded in one, the electrode of integral structure is made, the contact conduction of traditional assembled electrode is made to change into direct conduction side
Formula occurs the main portions of water electrolysis reaction in electrode net surface, eliminates contact resistance, reduces voltage needed for electrolysis, makes
Electrolysis power consumption used reduces.So under similarity condition, made from the equipment using the non-contact resistance electrode of the present invention
Hydrogen output is significantly larger than traditional preparation amounts of hydrogen.
And in electrode net surface nickel coating-aluminium alloy active coating, improve the electrolysis performance of electrode of the present invention.
In addition the electrolytic cell of non-contact resistance electrode assembly using the present invention, because of integral structure so that its institute of electrolytic cell
The quantity for the installation part wanted greatly reduces, and assembling process is simplified, and improves efficiency of assembling, and improves assembly matter
Amount.
