Graphical Abstract

Peroxide allowed: 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 O2 and H2O2, thus rendering 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 H2/CO and O2/H2O2.
