The qGP-DRT model successfully recovered the DRTs and impedances, the corresponding DRTs were in good agreement with DRTtools and ECM results (Figure , panels (b) and (d)). Welldefined peaks were consistently identified 𝜏 = 10 -4 s for all experimental conditions (Figure (f)). Furthermore, the low MSE norm,𝛾 and MSE norm,𝑍 values in Table confirmed the effectiveness of the qGP-DRT regression. Additionally, the narrow credible bands in Figure (d) indicated low uncertainty and high confidence in the recovered DRTs.
