摘要： A fuel pump driving module used for supplying fuel from a fuel tank to a fuel cell—and more particularly, a driving module for a diaphragm pump, and a fuel cell system equipped with the same—includes a pump controller for generating an ON/OFF signal and a reference pulse to a pump; and a pump driving pulse generation unit for combining the reference pulse according to a predetermined rule to determine a frequency and a duty ratio of the pump driving pulse and activating the pump driving pulse according to the ON/OFF signal to the pump. The pump driving module may be useful to commonly apply a single pump driving module to various manufacturers' fuel pumps, thereby to reduce the fabricating cost of the fuel cell system.
