Abstract: A method for diagnosing the operating state of an electrochemical system in real-time comprising a stack of cells, said method comprising steps for performing voltage measurements of said cells. Said method further comprises: real-time processing of the voltage measurements (61) thus performed, in order to extract specific waveforms (40) therefrom, converting said specific waveforms in order to generate specific points (65) therefrom of the real-time operation of the electrochemical system, and comparing these specific points of the real-time operation and specific points (75) of an off-line operation of the electrochemical system that originate from a conversion of specific waveforms (74) extracted from voltage measurements (78) performed off-line, while the electrochemical system is placed in known operating states including fault states, so as to produce information (69) relating to the real-time operating state of the electrochemical system.

Abstract: A method for controlling the operation of an electrochemical device having at least one operating organ, comprising the steps of: receiving measurements related to the operation of the electrochemical device, and estimating at least diagnostics data based on said measurements, estimating prognostics data based on said diagnostics data and providing operation instructions to control said operating organ of the electrochemical device, said operation instructions being optimized with respect to said estimated diagnostics and prognostics data.

Abstract: A method for detecting defects in an electrochemical device, including obtaining at least one characteristic value dependent on at least one variable received from the electrochemical device and determining at least one defect in said device from the characteristic value obtained. The method comprises a mathematical operation including a wavelet transform, which operation is carried out in order to obtain the characteristic value from the variable received. The invention also relates to a device that carries out one such method, as well as to a corresponding computer program.
