The FRC series X-in-1 fuel cell PCU integrates fuel cell DC-DC converter (DCF), EIS module(Electrochemical Impedance Spectroscopy), 24V output DC-DC converter, high-speed air compressor controller (ACC) and high-voltage power distribution unit (PDU), which greatly saves the space for the high-voltage electrical system and simplifies the design and installation of the power system.

Among them, the FRC4 series integrate boost DCF, the FRC5 series integrates buck­boost DCF
