Continuous health monitoring of solid oxide electrolyzers using pulse-width modulation current interrupt analysis

As solid oxide electrolyzer (SOE) technology moves from button cells to commercial stacks, there is a growing need for fast and inexpensive methods to track the stack’s state-of-health during operation. Electrochemical impedance spectroscopy (EIS) is the standard diagnostic at th...

The Potential of Operando DRIFT Spectroscopy for Studying Degradation Mechanisms of Metal Oxide‐Based Electrochemical Cells

ABSTRACT High‐temperature electrochemical oxide devices are promising for many applications. These devices are known to be prone to degradation, yet the mechanisms remain poorly understood. In this perspective, we summarize the techniques most used to study degradation in metal o...
