Fuel cell system and control method thereof

Abstract

A fuel cell system and a control method thereof; said system comprises a fuel cell generator (5), a fuel supply unit (6), a gas supply unit (7), a detection unit (8), and a control unit (9); said detection unit (8) is for detecting the discharge parameter of said fuel cell generator (5); said control unit (9) is for controlling fuel supply from said fuel supply unit (6) and gas supply from said gas supply unit (7) in accordance with the discharge parameter detected by said detection unit (8); wherein, said detection unit (8) is a current detection device, and the discharge parameter of said fuel cell generator (5) detected by said detection unit (8) is the discharge current value. The present invention utilizes the discharge current output from the fuel cell generator as the main parameter to control the fuel/gas supply units; therefore, the control is more direct and effective. In addition, the present invention can also control the working duration of said fuel and gas supply units to operate intermittently in accordance with the said discharge current value.
