The hydrogen oxidation reaction (HOR) occurred though the well-known Tafel-Heyrovsky-Volmer mechanism. The evaluation of this reaction on a Pt mesh electrode covered with a phosphoric acid doped PBI membrane at 160° is presented for the first time in this scientific contribution. In addition, the impact of impurities like methane and hydrogen sulfide on the HOR under HT-PEMFCs working conditions was investigated.
