This study evaluates the acoustic emission (AE) technique for the detection of membrane dehydration in proton exchange membrane fuel cells during operation. AE measurements were firstly carried out during dehydration of Nafion® samples (ex-situ study). As AE was shown to be sensitive enough to detect structural changes taking place at the last stages of dehydration, in-situ study was performed on PEM single cell during current interruption. AE activity occurs only on specific running conditions and consequently gives promises of further interesting applications. |
