TL;DR
The paper addresses aging modeling and lifetime prediction for Proton Exchange Membrane Fuel Cells (PEMFC) by integrating parametric identification, dynamic aging laws, and Extended Kalman Filtering (EKF). It develops a quasi-static electrochemical model, time-evolving parameters, and a Monte Carlo–augmented EKF framework to forecast voltage degradation and estimate Remaining Useful Life (RUL) under fixed operating conditions. A key contribution is the breakpoint-aware modeling of the limiting current density $j_{lim}$ and a change-detection criterion that triggers regime shifts, enabling more accurate long-term predictions. Results on a simulated aging database show accurate voltage forecasts (max MAPE around 0.82%) and precise RUL estimates (max mean APE around 0.22%), with the approach designed to quantify uncertainty and support prognostic health management for automotive PEMFC systems.
Abstract
This article presents a methodology that aims to model and to provide predictive capabilities for the lifetime of Proton Exchange Membrane Fuel Cell (PEMFC). The approach integrates parametric identification, dynamic modeling, and Extended Kalman Filtering (EKF). The foundation is laid with the creation of a representative aging database, emphasizing specific operating conditions. Electrochemical behavior is characterized through the identification of critical parameters. The methodology extends to capture the temporal evolution of the identified parameters. We also address challenges posed by the limiting current density through a differential analysis-based modeling technique and the detection of breakpoints. This approach, involving Monte Carlo simulations, is coupled with an EKF for predicting voltage degradation. The Remaining Useful Life (RUL) is also estimated. The results show that our approach accurately predicts future voltage and RUL with very low relative errors.
