3-D model of thermo-fluid and electrochemical for planar SOFC

Electrochemical characteristics and performance of anode-supported SOFCs fabricated using carbon microspheres as a pore-former

“…The fuel utilization efficiency for the single cells was estimated by dividing the maximum current density (at the zero voltage) obtained from IeV curves at the given fuel flow rates (Table 4) by the theoretical current-density (calculated by dividing the electrical current from Faraday's law [49] by the cell surface area that was 3.62 A cm À2 ). It is clear that the cells prepared by adding CMS exhibit a higher efficiency and maximum power density (Table 4).…”

Solid oxide fuel cell numerical study: modified MOLB-type and simple planar geometries with internal reforming

“…Porous electrodes and PEN structure are assembly to provide a functional material backbone at multi-scales for multi-physics processes such as: heat/ mass transfer, charge transport, electrochemical reaction, etc., and to enable direct conversion from chemical energy of hydrogen into electrical energy. Several investigations about MOLB-type without porous pipe and planar geometries fed by hydrogen in steady state operation have been carried out to calculate the temperature and current density distribution [13][14][15]. Kulikovsky [16] developed a model for anode performance of a planar-supported SOFC fed by hydrogen, Bessler et al [17] studied electrochemistry of SOFC anodes, focusing on the nickel/yttria-stabilized zirconia (Ni/YSZ) materials, and the electrochemical reactions were described in multi-steps in the Arrhenius form.…”

Numerical analysis of thermal stresses in a new design of microtubular stack

“…In addition, the temperature distributions of MEA for co-flow and counter-flow cases in planar solid oxide fuel cells were studied by Wang et al [7]. The average temperature of MEA were 979°C and 996°C in co-flow and counter-flow cases, respectively.…”

“…The temperature of MEA increased uniformly along the direction of fuel flow and was the highest near the fuel outlet for the co-flow case, while for the counter-flow case the temperature increased rapidly, reached a maximum of 1088°C near the fuel inlet and then gradually dropped. From these two considered flow configurations, the co-flow case had more uniform temperature distribution and smaller temperature gradients from the air inlet to the outlet [7]. Yakabe et al [8] performed a wide numerical analysis for a planar SOFC with double channels of co-flow or counter-flow pattern.…”
