<P>PROBLEM TO BE SOLVED: To improve responce by reducing pressure regulation error when the drive period of an on-off valve varies in a fuel cell system where the on-off valve such as an injector is disposed in a fuel supply passage. <P>SOLUTION: A fuel cell system 1 comprises a fuel cell 10, a fuel supply passage 31 which supplies fuel gas that is supplied from a fuel supply source 30 to the fuel cell 10, an on-off valve 35 which supplies gas on the upstream side of the fuel supply passage 31, while adjusting the state thereof, to the downstream side, and control means 4 which performs drive control of the on-off valve 35. The control means 4 calculates a feedforward correction flow rate based on the drive period of the on-off valve 35, corrects a command value of gas jet flow rate of the on-off valve 35 by using the feedforward correction flow rate, and performs drive control of the on-off valve 35 based on the command value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
