Innovative design to improve the power density of a solid oxide fuel cell

Micro-scale modelling of solid oxide fuel cells with micro-structurally graded electrodes

“…Hwang et al [4] developed a numerical model to investigate the characteristics of a mono-block-layerbuilt (MOLB) SOFC and they found that the MOLB-SOFC had a higher fuel/oxidant utilization than the planar SOFC. Ramakrishna et al [5] performed numerical analyses and proposed an innovative thin-walled geometry to improve the power density of SOFC. More recently, a novel 3-D SOFC was developed by Koh et al [6] to increase the volumetric power density by increasing the volumetric surface areas of the electrodes.…”

Technological development of hydrogen production by solid oxide electrolyzer cell (SOEC)

“…In the literature, several novel configurations have been proposed to improve the performance of solid oxide fuel cells, such as flat-tube high power density solid oxide fuel cell (HPD-SOFC), mono-block-layer-built solid oxide fuel cell (MOLB-SOFC), and the thin-walled solid oxide fuel cell [118][119][120][121]. In addition, recently, more investigators are interested in single chamber SOFCs and micro-SOFCs [122][123][124].…”

Three‐Dimensional Computational Fluid Dynamics Modeling of a Planar Solid Oxide Fuel Cell

“…This assumption greatly simplifies the mathematical model, but can cause considerable errors in predicting the temperature field and the performance of the SOFC, as numerical studies have shown that the Nusselt number varies significantly along the fuel cell gas channels [20,21]. Although some numerical studies included the developing laminar flow and heat transfer effect in the SOFC gas channels, the focus of those studies was to understand how the internal reforming reactions influence the SOFC performance [22][23][24][25] or to optimize the gas flow field to enhance the SOFC output [26][27][28]. As a result, the present literature is lacking a detailed parametric study on the effects of operating and structural parameters on SOFC performance from a 3D perspective.…”
