제목 Understanding of the Electrodes in Solid Oxide Fuel Cells  Using 2-Dimensional Image Analysis
초록 Solid oxide fuel cells (SOFCs) have been gaining widespread attention, due to pollution-free energy resources in replacement for the current fossil-based petroleum system. The electrochemical performance of SOFCs is crucially dependent on the porous microstructure in electrodes, i.e., both cathodes and anodes. The current work aims to characterizing of both cathode and anode layers in YSZ-based solid oxide fuel cells in terms of microstructural factors. The microstructural interpretation is performed using image analysis, which involves a   Electron Microscopy for capturing digital images and an commercially available image-processing software for statistical analysis. The detailed microstructural characterization includes the size, distribution, and contiguity of the corresponding constituents. Hence, in this work, we employ the image analysis microstructural information based on 2-dimensional images in the constituent phases in order to describe the electrodes in 3-dimensional aspects. The image processing approach will be connected with the corresponding unit cell configuration in solid oxide fuel cells. The synergetic approach will be discussed towards the optimization of solid oxide fuel cells.
