FUEL CELL SYSTEM AND POWER CONTROL METHOD

摘要

A fuel cell system comprises a fuel cell, and a power conversion unit which supplies AC power to a power system using DC power inputted from the fuel cell. The power conversion unit comprises: an inverter which converts DC power inputted from the fuel cell into AC power and outputs the AC power; and an auxiliary device which stores electric energy using DC power inputted from the fuel cell when an error is detected in the power system or the inverter, and supplies the stored electric energy to the inverter when the error is fixed.
