Abstract

A method and system for maintaining stability of a system of a fuel cell vehicle are provided to prevent malfunction of sensors of a low voltage DC-DC converter and the respective controllers. A start timing of a fault diagnosis for the low voltage DC-DC converter and the respective controllers is determined and a deviation between voltages of the sensors of the low voltage DC-DC converter and the respective controllers is detected to determine whether the low voltage DC-DC converter and the respective controllers fail.
