Abstract

Platinum metal cermet electrodes are described on which the electrochemical reduction of oxygen is made easier compared to known platinum metal cermet electrodes. The ceramic component of a platinum metal cermet electrode contains stabilized ZrO2 as its main constituent, the composition of the electrode being directed toward reducing its polarization resistance.
