Gaskets
 |
 ElectroChem offers a wide variety of pre-cut and bulk gasket material. The low precision silicone gaskets are sufficient for typical PEM fuel cell research. The thickness tolerance is +/- 2 mils, so proper thickness selection is critical. The high precision silicone gasket is similar, but has a thickness tolerance of +/- 0.5 mils. The Teflon and fiberglass reinforced Teflon are used in high temperature applications such as phosphoric acid fuel cells.
Replacement gaskets are available for all ElectroChem cells and stacks. The raw gasket material is also available in 30cm x 30cm sheets. Contact ElectroChem for other sizes and thickness. |
