“…These studies showed that the inclusion of SR and WGSR greatly influences the transport process and electrochemical performance of the cell. In addition to MSR, methane carbon dioxide reforming (MCDR) has also demonstrated to be feasible for SOFCs [24]. However, there is still no systematic modeling on SOFCs with MCDR.…”

IntroductionThe present chapter introduces a specifi c type of membrane reactor only briefl y mentioned in Chapter 1 . The solid electrolyte membrane reactor s ( SEMR ) -or electrochemical membrane reactors as they also are called -are equipped with ion -conducting membranes, which ideally are impermeable for non -charged reaction species. These reactors operate as electrochemical cells, in which the oxidation and reduction reactions are carried out separately on catalyst/electrodes layers located on the opposite sides of the electrolyte. The development of solid electrolyte membrane reactors has reached a semi -commercial stage in fuel cells, in which the maximal generation of electric energy by the total oxidation of hydrogen or hydrocarbon feeds is the primary goal of operation. Research on chemical reactor applications is strongly concentrated in the high -temperature range using either oxygen ion -or proton -conducting inorganic membranes. Some interesting examples were published recently, investigating proton -conducting polymeric membranes for the production of chemicals.This chapter gives a brief overview on the current status and future trends in the development and application of solid electrolyte reactors equipped with solid electrolyte ( SE ) materials used as membranes in these reactors. Initially the working principle of a solid electrolyte membrane reactor and material aspects are discussed. The second part of the chapter gives a detailed description of the special aspects concerning the modeling of solid electrolyte membrane reactors, as well as the application examples of maleic anhydride ( MA ) synthesis and oxidative dehydrogenation of ethane. Finally the chapter reviews recent papers concerning solid electrolyte membrane reactors applying:• high -temperature oxygen ion conductors, • high -temperature proton conductors, • low -temperature proton conductors.There are some recent review papers, especially written for high -temperature applications, which we would like to recommend to readers interested in more

“…For dry reforming, there was the risk of carbon deposition even though there was no visible carbon deposition in reported experiments (17). An efficient approach to avoid carbon deposition is by the operation of the cell under closecircuit conditions so as to provide sufficient oxygen from the cathode side to the anode side (18)(19) .…”

Biogas is composed of variable gases including hydrogen, nitrogen and sulphur, with methane and carbon dioxide as the main components. The common ratio of methane to carbon dioxide is 60/40 in volume and this high amount of methane causes carbon deposition when biogas is used in solid oxide fuel cells. To prevent carbon deposition, dry reforming, steam reforming or partial oxidation is the common method. In this paper, a nickel cermet solid oxide fuel cell was investigated with a simulated biogas based on 63% CH4 and 37% CO2, which was obtained by presuming 80% fuel utilisation and 25% recirculation of anode gas. Supplied with a 30 ml/min of simulated biogas, the cell generated a maximum power density of 856 mW cm-2 at 850 °C. The cell ran stably at loads of 100 mA cm-2, 300 mA cm-2and 500 mA cm-2 over a period of 16 hours at each level.
