“…Discussion on the performance of reference and counter electrodes was made in several papers, 19,27,30,35 particularly in relation to gas sensors, 18,26,28,39 and new techniques. 40,51,68 Gas phase chemical potential is sensitive to impurity gas particularly when the reactant gas is much diluted or gas mixing Electrochemistry, 82(10), 819-829 (2014) ratio of oxidant and reductant gases is very far from unity.…”

“…Therefore, gas flow rate is one of the important parameters to estimate the effect of impurity gas contamination from tubing system. 26,28 3.2 Fundamental electrochemical techniques employed in the present researches Similar to conventional studies on aqueous electrolyte systems, fundamental techniques are steady state polarization measurements and transient or relaxation techniques. Most of the research works were done using three-terminal methods.…”

“…In early stages, impedance methods are applied only for the conditions without dc current. [16][17][18][19][20][21][22][23][24][25][26][60][61][62] With the improvement of impedance analyzers, ac impedance measurements were going to be applied under dc bias as well as non-bias conditions. For the evaluation of impedance, the author's group essentially considers three types of parameters.…”

In order to survey history and state of art of theoretical and kinetic studies of gas electrode reaction on solid oxide electrolyte, overview was made on the research works reported by the author and his co-investigators. Through reviewing their works, frontier of research is clarified. It was shown that electrode reaction is controlled by nonfaradaic chemical reaction process, and the nature of the overpotential is the chemical potential deviation of the interface from equilibrium state. Mechanical stress at the electrode/solid electrolyte interface is considered varying with the overpotential. Importance is emphasized for mechano-electrochemistry, the field to study the relationship of electrochemistry and mechanical property of the electrochemical cells.

In order to elucidate the electrochemical reaction in a CH4-H20 system at the interface of a porous Pt electrode/Y203stabilized Zr02 electrolyte, measurements were made on the gas composition before and after the reaction under directcurrent polarization and on electrochemical impedance spectra at 1073 K. The dominant electrochemical reaction was found to be the redox process of H2/H20 where H2 and CO were generated by the steam reforming in a CH4-H20 system.
