Functionality
A fuel cell stack consists of a pile of cells consisting of bipolar plates, membrane electrode assemblies (MEAs), seals and end plates, plus the tensioning system.
Stack modules from ElringKlinger, however, also contains other system functionalities. These are integrated into a special media module made of plastic and typically contain sensors for pressure and temperature, valves, water separators for the anode circuit and optional customer-specific functionalities. These additional functionalities significantly simplify the integration of the stacks
into customer systems and result in a compact design.
