Coupling of methane was performed using SrCe[sub 0.95]Yb[sub 0.05]O[sub 3[minus]a]/Ag. On introducing methane and Ar into the anode and the cathode, respectively, and on passing the direct current through the cell, formation rates of C[sub 2]-compounds increased from 0.23 to 0.52 [mu]mol/min cm. From the measurement of the polarization characteristic, the partial pressure of hydrogen in the porous silver at the anode was found to be reduced by the electrochemical hydrogen pump. In addition, using a mixed conduction (protonic and p-type electronic conduction) of this ceramic, formation rates of C[sub 2]-products were accelerated further.
