“…Moreover, to analyze the system efficiently, parametric studies are also performed to observe the effects of different substantial parameters namely inlet pressure and temperature of the ORC turbine, and reference environment temperature in order to investigate the variations in the system performance in terms of the energy and exergy efficiencies. In another research, a hybrid system combining a gas turbine and a SOFC as a prime mover with a multi stage flash (MSF) desalination unit was carried out by Najafi et al [10]. The authors performed thermodynamic, economic and environmental (emissions cost) analysis and employed a multi-objective genetic algorithm (MOGA) to obtain the optimal design parameters of the plant.…”

“…Compared to the low temperature proton exchange membrane fuel cell (PEMFC) with its high Pt catalyst cost, easy catalyst poisoning, water and heat management problems andneed for extra auxiliary reforming, the high temperature solid oxide fuel cell (SOFC) has been studied more [1,2] due to its higher conversion efficiency, no need for Pt catalyst, and simpler system overall [3]. Solid proof of this difference could be garnered from the electronic journal system Science Direct.…”

Commercially available tapes (anode, electrolyte) and paste (cathode) were choosen to prepare anode-supported cells for solid oxide fuel cell applications. For both anode-supported cells or electrolyte-supported cells, the anode needs pretreatment to reduce NiO/YSZ to Ni/YSZ to increase its conductivity as well as its catalytic characteristics. In this study, the effects of different pretreatments (open-circuit, closed-circuit) on cathode and anodes as well as SOFC performance are investigated. To investigate the influence of closed-circuit pretreatment on the NiO/YSZ anode alone, a Pt cathode is utilized as reference for comparison with the LSM cathode. The characterization of the electrical resistance, AC impedance, and SOFC performance of the resulting electrodes and/or anode-supported cell were carried out. It's found that the influence of open-circuit pretreatment on the LSM cathode is limited. However, the influence of closed-circuit pretreatment on both the LSM cathode and NiO/YSZ anode and the resulting SOFC performance is profound. The effect of closed-circuit pretreatment on the NiO/YSZ anode is attributed to its change of electronic/pore structure as well as catalytic characteristics. With closed-circuit pretreatment, the SOFC performance improved greatly from the change of LSM cathode (and Pt reference) compared to the Ni/YSZ anode. OPEN ACCESSEnergies 2014, 7 3923

“…Solid oxide fuel cells (SOFCs) have also been investigated as part of this effort. SOFCs have the advantage of having a high efficiency of energy conversion and low carbon emission [1]. Therefore, several research institutions, specialists and scholars have devoted themselves to developing more efficient SOFCs using both experiments as well as numerical methods.…”

Carbon deposition considered in a solid oxide fuel cell (SOFC) model may be influenced by the operating voltage, inlet water/methane ratio, working temperature and pressure, inlet molar fraction of fuel and so on. The effects of these parameters in a planar SOFC implementing a novel bi-layer interconnector are not well understood. This paper is focused on the numerical study of carbon deposition and electrical performance of a bi-layer interconnector planar SOFC. The results illustrate that the electrical performance of the bi-layer interconnector SOFC is 11% higher than that of the conventional straight interconnector SOFC with initial state. After 120 days of operation, the electrical performance of the bi-layer interconnector SOFC has a slight decrease and more carbon deposit because of the increased electrochemical reaction rate. However, these differences minimize if higher operating voltages are involved.
