In this presentation, we will report the results of evaluating the interaction between the surface of AB₂-type hydrogen storage alloys and CO₂ using DFT calculations and in-situ X-ray photoelectron spectroscopy (XPS) under a gas atmosphere to clarify the effect of constituent elements on CO₂ poisoning tolerance.
