Abstract
A controlling device of a fuel cell system with multiple stack towers and a controlling method thereof are provided. The controlling device comprises a temperature sensing equipment, a processor and a pulse width modulation circuit. The fuel cell system comprises multiple fuel cell stacks. The controlling method further comprises: calculating an average temperature of the fuel cell stacks based on the temperatures of the fuel cell stacks by the temperature sensing equipment; determining whether differences between the average temperature and the temperatures of the fuel cell stacks fall within a preset range of average temperature difference by the processor, and adjusting an output current of at least one of the fuel cell stacks by the pulse width modulation circuit commanded by the processor when the difference between the average temperature and the temperature of the at least one fuel cell stack falls outside the preset range of average temperature difference.
