Abstract

A power net system of a fuel cell vehicle is provided. The power net system includes a fuel cell and a high-voltage battery unit connected in parallel via a main bus and a first switching unit that is configured to form and block an electrical connection between an output terminal of the fuel cell and the main bus. A load device diverges and is connected between the output terminal of the fuel cell and the first switching unit. A reverse current blocking unit is connected between the first switching unit and a node from which the load device diverges. A second switching unit is configured to form and block an electrical connection between the output terminal of the fuel cell and the load device. A controller operates the first and second switching units and adjusts the electrical connection state between the main bus and the high-voltage battery unit.
