This paper reports on the electrocatalytic nonoxidative dimerization of methane to ethane and ethylene that was studied at 750{degrees}C and 1 atm. The electrochemical cell used as Ag/SrCa{sub 0.95}Yb{sub 0.05}O{sub 3}/Ag where the solid electrolyte was a proton conductor. By applying a current to the cell H{sup +} was pumped to or from the Ag electrodes. Under closed circuit the rate of methane dehydrogenation to ethane and ethylene could increase to as much as eight times the open-circuit rate. The electrolyte cell offers a promising advantage over conventional catalyst supports.
