Role of Fe in the hydrogen oxidation reaction in a NiFe-based catalyst: an in situ Mössbauer spectroscopic investigation
Nickel-based catalysts reach a high activity for the hydrogen oxidation reaction (HOR) in anion exchange membrane fuel cells. While incorporation of iron significantly decreases the HOR overpotential on NiFe-based catalysts, the reason for the enhanced activity remains only partially understood. For...
