A method and system for diagnosing the operating state of an electrochemical system in real time, and an electrochemical system comprising the diagnostic system

摘要

A method for diagnosing in real time an operating state of an electrochemical system comprising a stack of cells, the method comprising steps for performing voltage measurements of the cells. The method comprises: real-time processing of voltage measurements 61 performed accordingly to extract specific waveforms 40 from voltage, specific points 65 of the real-time operation of an electrochemical system, and the specific waveforms. Converting the particular waveforms to generate from and real-time operation while the electrochemical system is placed in known operating states, including fault conditions, to generate information 69 related to the real-time operating state of the electrochemical system. These specific points of are compared to specific points 75 of the off-line operation of the electrochemical system resulting from the conversion of the particular waveforms 74 extracted from the voltage measurements 78 taken off-line. It further comprises a step.
