Abstract: | By analyzing the structure and working principles of a proton exchange membrane fuel cell (PEMFC) system, the paper presents two feasible schemes of a fuel cell voltage monitoring system based on double�control area network(double�CAN) network and an online fuel cell impedance measurement system based on electrochemical impedance spectroscopy (EIS), respectively. In consideration of the structural and multi�sensor characteristics of the PEMFC system, a fault diagnosis method based on distributed neural network was proposed and further elaborated, which proved to simplify the process of the fault diagnosis and improve its real�time performance, as well as better the PEMFC system�s working stability and reliability. |
Key words: | automatic control technology; fault diagnosis; distributed neural network; proton exchange membrane fuel cell |
