This presentation will deal with the use of operando methods for mechanistic studies energy systems with emphasis on fuel cells and battery materials and technologies. The presentation will begin with a brief overview of the methods employed with emphasis on the use of X-ray based methods, transmission electron microscopy (TEM) under active potential control and confocal Raman spectroscopy. The utility of these methods will be illustrated by case studies focusing on non-precious metal electrocatalysts for the oxygen reduction reaction (ORR) in alkaline media, Li/S batteries and the reduction of carbon dioxide. The presentation will conclude with an assessment of future directions.
