Development of efficient fuel cell and electrochemical cell devices to retrieve energy in a renewable manner lies in the molecular level understanding of the catalytic chemical transformation processes at surfaces and interfaces. This article demonstrates the use of operando soft x-ray photoelectron spectroscopy to correlate the chemical state of electrode and the electrochemical performance of electrochemical devices. Examples are shown for oxygen reduction reaction on the Pt cathode catalyst in proton exchange membrane fuel cells, and oxygen evolution on the IrO2 anode in water electrolyzer.
