Metallic bipolar plates
ElringKlinger develops and produces metallic bipolar plates for polymer electrolyte membrane fuel cells (PEMFCs) by means of a fully automated manufacturing process that includes high-precision progressive tools suitable for large-scale serial production. Metallic bipolar plates for PEMFCs offer tangible advantages with regard to costs and – an aspect that is particularly important for mobile applications – power density. In addition, they help to ensure the cold-start capability of fuel cells. Given its long-standing experience in the development, optimization and automated production of components for PEMFCs, ElringKlinger is well equipped to tackle the challenges of the future.
Casings, end and media modules – key stack components
As central components of the fuel cell stack, intelligently stacked bipolar plates have to be permanently braced with a uniform contact pressure over the entire surface of the cell. This is achieved by means of end modules that comprise the clamping system and, where necessary, media modules for the best possible supply of the functional units. Production-ready end modules for PEMFCs consist of high-performance plastics that meet all requirements while also offering the benefits of low weight and excellent dimensional stability. They offer the benefits of mechanical stability, chemical resistance and lightweight design. Using process-consistent injection molding, ElringKlinger is able to produce highly complex end modules that incorporate a range of system assemblies. Casings protect the fuel cell stack and its components from external influences.
Depending on the area of application, the key benefits of the materials used by ElringKlinger are as follows:
- High thermal stability
- Low weight
- Flexibility in design
- Easy assembly
Plastics are used in the production of PEMFC housings. In addition to saving weight, this helps to reduce the overall cost of components.
