A Survey of Diagnostic of Fuel Cell Stack Systems

Fuel cells are electrochemical energy conversion devices that convert hydrogen and oxygen into water, producing electricity and heat in the process. Fuel cell is one of the best alternatives of fossil energy. Recently, the research community of fuel cell has shown a considerable interest for diagnosis in view to ensure safety, security, and availability when faults occur in the process. These faults must be detected early and sometime estimated and accommodated. Therefore, they are vulnerable to faults that can cause the stop or the permanent damage of the fuel cell. To guarantee the safe operation of the fuel cell systems, it is necessary to use systematic techniques to detect and isolate faults. The present paper presents a survey and analysis of different techniques used for diagnostic of Fuel Cell Stack System.
