Effect of Composite Electrode Microstructure on Temperature Distribution in Solid Oxide Fuel Cells
Temperature distributions in the solid structure of planar solid oxide fuel cells with various microstructures of composite electrodes are studied through the combined micro and macro cell modeling. The results of the computer simulation reveal that the composite electrode microstructure can play a significant role in the mean temperature, temperature difference between the hottest and coldest spots, and maximum temperature gradient in the solid structure of the cell. The variation of these three parameters at different electrodes microstructural variables – including porosity, thickness, particle size ratio, and the size and volume fraction of particles – is quantified in this article.
