Recursive, time series-based method for determining the state of an electrochemical reactor

摘要

The present invention relates to a method for determining the state of an electrochemical reactor (1), comprising the steps of: operating an electrode section (2) of the electrochemical reactor (1) for generating a harmonic current and voltage signal through the electrode section (2), and model-based estimation of Amplitude and / or phase of the harmonic current and voltage signal, based on the estimate of the state of the electrochemical reactor (1) is determined, wherein a recursive, time series based method is used to estimate the amplitude and / or phase of the harmonic current and voltage signal , Furthermore, the invention relates to a diagnostic system (3), a computer program product (5) and a storage means (6).
