Gaskets provide correct compression and act as a ‘barrier’ for potential fuel leaks; maximizing the highest possible efficiency.

Gaskets are an important component for a fuel cell. It also works as a sealing agent for the fuel cell assembly. The proper selection of a gasket is dependent on various parameters such as the operating temperature of the cell, the thickness of the MEA, etc.

ElectroChem offers pre-cut and bulk gasket material from three materials; silicone, Teflon, and fiberglass.

The Teflon and fiberglass reinforced Teflon are used in high temperature applications such as Hi Temperature PEM fuel cells or phosphoric acid fuel cell.

Replacement gaskets are available for all ElectroChem cells and stacks. The raw gasket material is also available in 12” by 12” (30cm X 30cm) sheets.
