Abstract

The equivalent circuit model of the proton exchange membrane electrolyzer (PEMEL) is of significant importance for analyzing the dynamic response when connecting the electrolyzer (EL) to intermittent renewable resources. This paper proposes a least root mean square error (least-RMSE) method for obtaining the cathode time constant of a PEMEL’s equivalent circuit. The accuracy of the method is confirmed by the calculation of the RMSE and absolute error (AE) between obtained simulation results of the proposed method and experimental data from the previous studies. The acquired results indicate the self-tuning estimation approach has improved significantly RMSE and AE in comparison with other methods to identify the time constant of the cathode.
