We tested how well the constrained fGP-DRT model deconvolves the DRT when the EIS data is truncated relative to those used in Sections 3. For further validation, we considered the ECM described in with the data being truncated below 10 -3 Hz. The specific parameters of this ECM are reported in Table . Our model successfully recovers the real and imaginary components of the impedance. Additionally, the DRT is estimated in a satisfactory manner together with its error bands (Figure ). Hz (𝜎 𝑛 exp = 0.5 Ω) relative to the data presented in Figure with the corresponding recovered DRT in (d), (e), and (f), and real and imaginary parts of the impedance in (g), (h), and (i).
