Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

We report differential electrochemical mass spectrometry (DEMS) measurements on blocking effects induced by adsorbed CO or surface oxide on the hydrogen oxidation reaction (HOR) on a polycrystalline Pt electrode, comparing also with earlier results obtained on a thin-film Pt/Vulcan supported catalyst electrode.
