Description

Outdoor electrolytic tank subjected to insulation treatment

Technical Field

Therefore, hydrogen energy facilities represented by electrolytic cells play a critical role in reducing the cost of hydrogen production.

The hydrogen production by electrolyzing water is characterized by that the direct current is introduced into the electrolytic bath full of electrolyte, and the water molecules produce electrochemical reaction on the electrode, and its principle is that at the cathode the water molecules are decomposed into H⁺And OH^-，H⁺The electron is generated into hydrogen atom, and further hydrogen molecule (H) is generated₂)；OH^-Then the water passes through the porous diaphragm under the action of the electric field force between the cathode and the anode and reaches the anode, and the electrons are lost at the anode to generate a water molecule and an oxygen molecule, so that zero emission can be realized in the whole process.

The current electrolytic cell is slow in development speed, the previous electrolytic cells are small and medium sized and are basically indoors, and the consumption is low, such as aerospace hydrogen production, submarine oxygen production, nuclear power or cooling hydrogen production of thermal power units. However, the existing green energy sources reach the ton level, are increased by hundreds of thousands of times and need to be installed in outdoor environments, the current technical means avoids electric shock, power connection and other accidents caused by rainwater, sundries and animals and plants and disasters such as fire and the like by installing an electrolytic cell in a mechanism (forming a semi-closed space) similar to a container, but avoids the explosion hidden danger of closing the semi-closed space after hydrogen leakage is avoided, the large-scale hydrogen production puts higher requirements on the safety of the self, the placing environment needs to be lowered to increase the safety, and the core needing to be improved is the insulating property.
