The electrolytic bath is divided into three types, namely an aqueous solution electrolytic bath, a molten salt electrolytic bath and a non-aqueous solution electrolytic bath according to the difference of the electrolyte.

In order to prevent the mixing of the products of the cathode and anode and to avoid possible harmful reactions, the cathode and anode chambers are substantially separated by a diaphragm in the cell. The membrane should have a porosity that allows ions to pass through it, but not molecules or bubbles, and the ohmic drop of the membrane should be low when a current flows through it. These properties are required to be substantially unchanged during use and to have good chemical stability and mechanical strength under the action of the electrolytes in the cathode and anode chambers. When water is electrolyzed, the electrolytes in the cathode chamber and the anode chamber are the same, and the diaphragm of the electrolytic cell only needs to separate the cathode chamber and the anode chamber to ensure the purity of hydrogen and oxygen and prevent the explosion of mixed hydrogen and oxygen.
