OXIDATION OF METHANE OVER PLATINUM IN A SOLID PROTON-CONDUCTING ELECTROLYTE CELL

Studies of the complete oxidation of methane on a Pt electrode-catalys t in the cell with a solid proton-conducting electrolyte (CH4 + O-2, P t\SrCe0.92Dy0.08O3\Pt, H2O + N-2) were carried out. The non-Faradaic e ffect of electrochemical hydrogen pumping on the rate of methane oxida tion has been demonstrated. The induced change in the reaction rate at anodic polarization of a Pt electrode-catalyst was over two orders of magnitude higher than the rate of hydrogen pumping from the reaction zone through the electrolyte.
