2D thermal modeling of a solid oxide electrolyzer cell (SOEC) for syngas production by H2O/CO2 co-electrolysis
Solid oxide fuel cells (SOFCs) can be operated in a reversed mode as electrolyzer cells for electrolysis of H2O and CO2. In this paper, a 2D thermal model is developed to study the heat/mass transfer and chemical/electrochemical reactions in a solid oxide electrolyzer cell (SOEC) for H2O/CO2 co-electrolysis. The model is based on 3 sub-models: a computational fluid dynamics (CFD) model describi...
متن کاملA bifunctional solid oxide electrolysis cell for simultaneous CO2 utilization and synthesis gas production.
We hereby report on a pioneering and inspiring solid oxide cell which, assisted by natural gas, utilizes a bifunctional electrolysis cell configuration to effectively consume CO2 to produce CO at the cathode side and simultaneously synthesize highly valuable syngas (mixture of CO and H2) at the anode side via a one-step green process.

In this study, an electrochemical m...
متن کاملSyngas (CO-H2) production using high temperature micro-tubular solid oxide electrolysers
CO2 and/or H2O were reduced to CO/H2 in micro-tubular solid oxide electrolysers with yttria-stabilized zirconia (YSZ) electrolyte, Ni-YSZ cermet cathode and strontium(II)-doped lanthanum manganite (LSM) oxygen-evolving anode. At 822 C, the kinetics of CO2 reduction were slower (ca. 0.49 A cm 2 at 1.8 V) than H2O reduction or co-reduction of CO2 and H2O, which were comparable (ca. 0.83 to 0.77 A...
متن کاملfaciliting lexical access for the fluent production of speech
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
