Fuel cell control unit (FCCU)

Block diagram

Overview

Our integrated circuits and reference designs help you create fuel cell control unit (FCCU) designs that enable efficient transfer of energy from the fuel cell stack to other power rails.

Design requirements

FCCU designs require:

  • Simplified and efficient integration of unidirectional DC/DC converters.
  • Monitoring and controlling fuel cell stack systems for safety and efficiency.
  • Following state-of-the-art architecture regarding system redundancy in order to allow implementation of the system on the highest safety level.
