A fuel cell power distribution unit (PDU) is a critical component in a fuel cell system that distributes low voltage power to various internal electrical appliances and subsystems. It ensures that the power generated by the fuel cell is effectively distributed to all necessary components within the system.

It provides centralized power distribution, protection against electrical faults, control and monitoring of power parameters, safety features, and efficiency enhancements. This component ensures that the fuel cell system operates smoothly, reliably, and safely while meeting the power needs of all connected devices and systems.
