Description
Technical field
The present invention relates to a kind of water electrolyser non-contact resistance electrode, belong to water electrolysis hydrogen producing technical field.
Background technology
Typical water electrolysis hydrogen producing electrolysis bath is in series by several tank houses, runs under big electric current, low voltage condition, and electrode is the element of tank house.Electrode is made up of battery lead plate, supporter, electrode network, or is made up of battery lead plate, the electrode network of band supporting construction.Electrode is passed through unidirectional current when being electrolysed, and between these parts, the conduction of electric current is contact electrically conducting manner, and the contact resistance therefore produced is unavoidable.
Water electrolyser is a load having certain resistance value, and its resistance value is bath resistance, bubble resistance, membrane electrical resistance, polarization resistance, contact resistance sum.The theoretical decomposition voltage of water is 1.23V, electrolytic process must be carried out under conditions of higher than decomposition voltage, for meeting the requirement of gas production, it is accomplished by maintaining specified electric current density, the impact overcoming electrolysis bath resistance must apply certain voltage, and therefore the power consumption of electrolysis bath unit gas production is bigger.
There is contact resistance each other in electrode, prior art reduces the resistance of contact resistance usually through the means changing electrode surface material, but in use, due to the reason such as impurity in electrolyte, electrode surface material can be lost its original effect by impurity effect, the most significantly add the resistance of contact resistance between electrode, increase power consumption.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes the electrode of a kind of non-contact resistance formula in water electrolyser.
The present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of non-contact resistance electrode, described non-contact resistance electrode includes electrode plate assembly, electrode support and electrode network；Described electrode plate assembly includes metal electrode frame and the main electrode plate being welded in described metal electrode frame, described metal electrode frame both sides are provided with annular boss, being welded with described electrode network on described annular boss, described electrode support is welded between described electrode network and described main electrode plate.
The improvement of technique scheme is: described metal electrode frame is carbon steel electrode frame, and described main electrode plate is cold-rolling deep-punching steel plate battery lead plate.
The improvement of technique scheme is: described electrode support is sheet metal silk screen.
The improvement of technique scheme is: described electrode support is some projections that array is arranged on described main electrode plate.
The improvement of technique scheme is: described electrode network is worked out by nickel or nickel alloy, and described electrode network surface-coated has nickel-aluminum alloy active coating.
The present invention uses technique scheme to provide the benefit that: by main electrode plate, electrode support and electrode network are welded in one, it is formed integrally the electrode of formula structure, the contact conduction making traditional assembled electrode changes into direct conduction mode, occur the main portions of water electrolysis reaction on electrode network surface, eliminate contact resistance, reduce electrolysis required voltage, make power consumption used by electrolysis reduce.So under similarity condition, the hydrogen output using the equipment of the non-contact resistance electrode of the present invention to prepare is significantly larger than traditional preparation amounts of hydrogen.
And at electrode network surface-coated nickel-aluminum alloy active coating, improve the electrolysis performance of electrode of the present invention.
In addition using the electrolysis bath that the non-contact resistance electrode of the present invention assembles, because integral structure makes the quantity of its desired installation part of electrolysis bath greatly reduce, assembling process is simplified, and improves efficiency of assembling, and improves assembling quality.
