Researchers have developed a novel physics-informed convolutional autoencoder designed to estimate the distribution of relaxation times (DRT) from electrochemical impedance spectroscopy (EIS) data. This method addresses the ill-posed nature of the inverse problem by embedding a discretized relationship between impedance and DRT into the training process, ensuring impedance-consistent outputs. The model has demonstrated its ability to resolve overlapping relaxation processes and accurately reconstruct measurements from solid oxide fuel and electrolysis cell datasets, achieving low error rates. Furthermore, the learned latent representation within the model is organized by relaxation timescale, enabling effective condition monitoring by capturing operating changes and long-term degradation.
