Electrolytic cell sealing gasket

The function of the sealing gasket for electrolytic cells

The sealing gasket of the electrolytic cell is a key component in the electrolytic cell, mainly used to form a leak-proof seal between different components of the electrolytic cell stack (such as between bipolar plates or between the stack and end plates). Its main functions include:

Prevent gas leakage: Ensure that hydrogen and oxygen do not leak to avoid potential safety hazards.

Prevent liquid leakage: Prevent electrolyte leakage to ensure the efficient operation of the electrolytic cell.

Insulation and support: It provides insulation function and offers support for the structure of the electrolytic cell.

2. Material selection

The sealing gasket of the electrolytic cell needs to remain stable in high-temperature, high-pressure and corrosive environments, so the selection of materials is of vital importance. Common materials include:

Elastomers and polymers: such as ethylene propylene diene monomer (EPDM) rubber, which has excellent chemical resistance and mechanical properties.

Composite materials: such as reinforcing layers woven from metal wire and polyester wire, used to enhance the strength and durability of gaskets.

Silica gel and polyurethane: Used in proton exchange membrane (PEM) electrolyzers, they feature low hydrogen permeability and good elasticity.

Hydrolysis-resistant polyurethane resin: It exhibits excellent stability in alkaline and anion exchange membrane (AEM) electrolytic cells
