Review demonstrates optical and spectroscopic methods for tracking real-time degradation in solid-oxide fuel cells, highlighting pathways toward next-generation durable energy devices.

Key Points

To review the capabilities, advantages, and limitations of in situ optical diagnostics—specifically thermal imaging and vibrational spectroscopy—for directly observing physical and chemical processes in operating solid-oxide fuel cells.
Evaluated real-time in situ diagnostic approaches, including high-temperature thermal imaging and vibrational spectroscopy, applied to fuel cells running at temperatures above 600 °C.
Compared diagnostic capabilities of live optical techniques to standard electrochemical evaluations, kinetic models, and postmortem ex situ analyses.
Thermal imaging resolves local temperature gradients down to 0.1 °C across fuel cell electrodes operating above 600 °C.
Vibrational spectroscopy successfully identifies transient molecular species and material phase transitions in real time, uncovering reaction mechanisms that cannot be resolved through voltammetry or impedance spectroscopy alone.
