Wherein, the hydrogen production by water electrolysis is a more convenient method for preparing hydrogen. And D, introducing direct current into the electrolytic tank filled with the electrolyte, and enabling water molecules to undergo electrochemical reaction on the electrodes, so that the water molecules can be decomposed into hydrogen and oxygen.

In the hydrogen production by electrolysis of water, the electrolysis process is generally performed in an electrolytic cell composed of a cell body, an anode and a cathode, and the anode chamber and the cathode chamber are partitioned by a diaphragm. When the direct current passes through the electrolytic cell, oxidation reaction occurs at the interface between the anode and the solution, and reduction reaction occurs at the interface between the cathode and the solution, so as to prepare the required product.

However, currently, in the production of hydrogen using electrolyzed water, there are the following problems: the dynamic processes of electrochemical hydrogen evolution and oxygen evolution are different, so that the hydrogen production speed and the oxygen production speed are different, the pressure on two sides of the diaphragm is different, the loss of the diaphragm is serious, and the diaphragm needs to be replaced periodically; however, when the existing electrolytic tank is assembled, the existing electrolytic tank is usually assembled in a welding or bolting mode, and although the stability of the electrolytic tank after assembly is high, the assembly is troublesome, the assembly efficiency is low, and when the electrolytic tank is used for a period of time, the diaphragm in the electrolytic tank needs to be replaced, the disassembly is inconvenient.

And cleaning the residual materials adhered in the die, polishing and finishing, and pressing the next diaphragm gasket. Therefore, the preparation process of the diaphragm gasket is complex and long, and on the premise of uniform powder mixing, more than 4 hours are needed for pressing one diaphragm gasket, and only 2 diaphragm gaskets can be produced by a single person per shift, so that the production efficiency of the diaphragm gasket is low, the cost is high, and the development of the whole hydrogen production system by water electrolysis is seriously influenced.

Therefore, developing a diaphragm gasket with simple structure, low manufacturing cost, high efficiency and convenient disassembly and assembly is one of the technical problems to be solved urgently by those skilled in the art.
