“…The search for more-active catalysts made it possible to operate at lower temperatures and pressures. Also, parallel to the catalyst optimization, several alternative processes have been proposed including the electrochemical synthesis in SECRs. ,− ,,− , The reaction was first studied by Marnellos et al , in a H + SECR on Pd electrodes. Yokari et al used a single-chamber reactor and studied the reaction on a commercial Fe catalyst.…”

Solid electrolytes have found applications in several areas, including (a) sensors, (b) separators, (c) solid oxide fuel cells, and (d) solid-state batteries. In addition, solid electrolytes have been used in the construction of solid electrolyte cell reactors (SECRs), in which heterogeneous catalytic reactions have been studied. Also, SECRs have been used as chemical cogenerative fuel cells, i.e., for the simultaneous production of electricity and useful compounds. In the present work, a survey of the studies conducted in SECRs is presented. The fundamental operating principles, results in technologically important reactions, and the hurdles that should be overcome to bring SECRs into industrial practice are discussed.

“…Conversion in MIEC membranes is primarily a chemical process driven by the chemical potential difference of oxygen across the membrane, where the electrons as well as either oxide ions or protons may diffuse across the membrane to accomplish the desired chemical reaction of oxygenation or dehydrogenation. Another approach to produce electricity and chemicals consists of employing an electrochemical reactor that utilizes a proton conducting solid electrolyte in a SOFC configuration, where the methane transformation reactions are dominated by proton extraction [44][45][46][47]. Both of these schemes, namely, MIEC ceramic membrane reactors and electrochemical reactors based on protonically conducting solid oxide electrolyte membranes, fall outside the scope of this review article and will not be covered here.…”
