Multifunctional Catalysts for H2O2-Resistant Hydrogen Fuel Cells

摘要

The development of hydrogen fuel cells is greatly hindered by the unwanted generation of H2O2 at the cathode. A non-Pt cathode catalyst is now shown to be capable of simultaneously reducing both O-2 and H2O2 thus rendering 1-1 H2O2, a useful part of the feed stream. The applicability of this unique catalyst is demonstrated by employing it in a fuel cell running on H-2/CO and O-2/H2O2.
