Abstract

Abstract: The paper focuses on new methods of Proton Exchange Membrane Fuel Cells diagnostics, which would allow increasing the reliability and stability of fuel cell operation. The paper considers the possibility to improve the diagnostic system used for fuel cell robustness check. Wavelet analysis as a diagnostic tool is introduced, and it is proven that this type of instrument allows acquiring a higher quality of early-stage problem diagnostics in comparison to existing methods. The suggested system assesses the possibility of determining the changes in the fuel cell operating mode on the basis of the analysis of its electrical fluctuations. Both theoretical and practical implications of the suggested diagnostics method are discussed.
