Fuel cell stack modules

A fuel cell stack module is a stack of cells consisting of a large number of bipolar plates, membrane electrode assemblies (MEAs), seals, end plates, and the tensioning system. Stack modules from EKPO contain additional system functionalities that greatly simplify integration into customer systems and result in a compact design. A special media supply assembly usually integrates pressure and temperature sensors, valves, water separators for the anode circuit, and optional customer-specific functions.
