Data‐Driven Temperature Deviation Estimation of a Proton Exchange Membrane Water Electrolyzer Stack from Electrochemical Impedance Using Machine Learning

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
We developed a method to analyze temperature variations in proton exchange membrane water electrolysis stacks by using machine learning to interpret electrochemical impedance spectroscopy (EIS) data. To train the machine learning model, we artificially generated impedance data at various temperature differences by merging data from uniformly heated ...
