Electrochemical Low-Frequency Impedance Spectroscopy for Diagnostics of Fuel Cells
Diagnostics of the state of health of fuel cells is important for their safe operation and to maximise their lifetime. The low-frequency intercept of a fuel cell’s electrochemical impedance spectrum with the real axis is a good prognostic variable that changes linearly with degradation. Using relay feedback, it is possible to estimate this parameter on-line without a full impedance spectroscopy, with a lightweight algorithm that can be realised with a typical fuel cell control unit. The proposed method is tested in simulations and experiments, and demonstrated convergence times of just a few seconds.
