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.
