Fuel Cells

A fuel cell stack is usually a stack of cells consisting of bipolar plates, membrane electrode assemblies (MEAs), seals and end plates, and the tensioning system. Stack modules from ElringKlinger also include other system functionalities that make integration into customer systems vastly easier and significantly reduce the potential for leakages in the system.

Fuel Cell Gaskets, Spacers, and End Plates

The traditional fuel cell stack is designed with surfaces (bipolar and end plates) that are parallel to one another with a high degree of precision. The end plate must be mechanically sturdy enough to support the fuel cell stack, and be able to uniformly distribute the compression forces to all of the major surfaces of each fuel cell of the fuel cell stack.
