A review on fault diagnosis tools of the proton exchange Membrane Fuel Cell

Fuel Cells received a major research interest in the past few years. However, despite their promising features, Fuel Cell systems still lack a solid fault diagnosis and predictive maintenance study. There are numerous faults that have to be detected and diagnosed on a fuel cell power generator system, ranging from chemical faults, to electrical and power electronics faults. Several fault diagnosis techniques were proposed in literature. This paper presents an overview on all those fault diagnosis tools, analyze their effectiveness, and highlight their drawbacks if any.
