We have demonstrated a hydrogen electrooxidation in the gas phase by employing a Nafion-coated integrated ultramicroelectrode, which represents the three-phase interface of a membrane assembled electrode for a polymer electrolyte fuel cell. The limiting current of gas-phase hydrogen oxidation is proven to be more than ten times larger than that in hydrogen saturated water.
