The fuel-cell control unit (FCCU) is the central control unit for operation of the fuel-cell system – or “electrical power plant” – of an electric vehicle equipped with a fuel cell.

The FCCU controls operation of the fuel-cell system with its individual sub-systems, such as the hydrogen supply, air system, thermal and water-management systems, and the tank system. A monitoring concept is integrated into the FCCU to safeguard the system’s operation.
