Abstract :
The gas pressure control is very important in PEMFC system. Based on the analyses of PEMFC working process and basic property, this paper presents a new PID control algorithm with changeable digital input adapted to PEMFC working characters, which can make the PEM gas pressure of each side in the relatively controllable steady state. The experiment results demonstrate that such method can well realize double-loop pressure control of PEMFC system. In the PID control, either-gas-loop control is steady and double-gas-loop control is coordinate.
