Abstract
The oxidation of hydrogen at the interface of nickel and the perovskit e proton conductor Sr0.995Ce0.95Y0.05O2.975 has been investigated at 8 00 degrees C and below in atmospheres of N-2/H-2/H2O, using a point co ntact electrode technique. The polarisation behaviour obtained in the anodic regime suggested the transport of a species undergoing one elec tron transfer. Limiting currents were dependent on the partial pressur e of hydrogen, but not on that of water vapour.
