Item type:Publication, Design and evaluation of the sorption enhanced steam reforming and solid oxide fuel cell integrated system with anode exhaust gas recirculation for combined heat and power generation(2017-01-01); ; Arpornwichanop, AmornchaiSolid oxide fuel cell (SOFC) is an electrochemical device for power generation with high efficiency and low environmental impact. Due to a high-temperature operation of SOFC, useful heat can be recovered to enhance its system efficiency. Regarding the environmental concern, bio-oil, the renewable liquid fuel, can be applied to SOFC system. In this study, the SOFC integrated with a steam reforming of bio-oil is considered. A sorption enhanced reforming process is studied for the production of high purity hydrogen for SOFC, and the anode gas recirculation in the SOFC system is proposed for the system improvement. Modeling of such an integrated process is performed using Aspen Plus simulator. As heat and power are generated from the SOFC system, the effect of key design parameters; fuel utilization and recirculation ratio of the anode gas, on a heatto-power ratio is analyzed. The system performance regarding to the electrical and thermal efficiencies is also evaluated. The results show that increasing the anode recirculation ratio increases the combined heat and power (CHP) performance, but increasing the fuel utilization decreases the thermal efficiency. It is also found that the appropriate range of heat-to-power ratio of the system varies from 0.24 to 0.89. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Modeling and optimization of proton-conducting solid oxide electrolysis cell: Conversion of CO2 into value-added products(2016-11-01); Arpornwichanop, AmornchaiProton-conducting solid oxide electrolysis cells (SOEC-H<sup>+</sup>) are a promising technology that can utilize carbon dioxide to produce syngas. In this work, a detailed electrochemical model was developed to predict the behavior of SOEC-H<sup>+</sup> and to prove the assumption that the syngas is produced through a reversible water gas-shift (RWGS) reaction. The simulation results obtained from the model, which took into account all of the cell voltage losses (i.e., ohmic, activation, and concentration losses), were validated using experimental data to evaluate the unknown parameters. The developed model was employed to examine the structural and operational parameters. It is found that the cathode-supported SOEC-H<sup>+</sup> is the best configuration because it requires the lowest cell potential. SOEC-H<sup>+</sup> operated favorably at high temperatures and low pressures. Furthermore, the simulation results revealed that the optimal S/C molar ratio for syngas production, which can be used for methanol synthesis, is approximately 3.9 (at a constant temperature and pressure). The SOEC-H<sup>+</sup> was optimized using a response surface methodology, which was used to determine the optimal operating conditions to minimize the cell potential and maximize the carbon dioxide flow rate. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Effect of anode-cathode exhaust gas recirculation on energy recuperation in a solid oxide fuel cell-gas turbine hybrid power system(2016-01-01); Arpornwichanop, AmornchaiA solid oxide fuel cell-gas turbine (SOFC-GT) hybrid system supplying liquid fuel as ethanol exhibits promise as an auxiliary power unit. In this study, the recirculation of anode and cathode exhaust gas in the SOFC-GT system is proposed to improve the efficiency of heat management in the SOFC-GT hybrid system. The key operating parameters, such as fuel utilization factor and the cell and GT temperatures, are analyzed in terms of the performance of the SOFC-GT hybrid systems. The simulation results show that the recirculation of anode and cathode exhaust gas has a direct impact on the turbine performance. To maintain the inlet temperature of the small turbine in the range of 873-1223 K, the amount of fuel and air added to the combustor to control the turbine inlet temperature on the system performance is also investigated. A SOFC-GT hybrid system with both anode and cathode exhaust gas recirculation achieves the highest system and thermal efficiency. - Some of the metrics are blocked by yourconsent settings
