AB  - The invention relates to a method and a system for diagnosing an electrochemical transducer, as well as a computer program product. A method (1) for diagnosing an electrochemical transducer comprises exciting (4) the electrochemical transducer with excitation signals and detecting (5) response signals from the electrochemical transducer in response to the excitation signals. The excitation (4) of the electrochemical transducer occurs only at representative measurement frequencies. In particular, the representative measurement frequencies and the reconstruction are based on a basis of eigenvectors or spectra determined by means of a set of EIS measurements. This enables high-quality reconstruction of the electrochemical impedance spectrum based on a significantly reduced number of measurements.
