Modelling the 3D Microstructure and Performance of Solid Oxide Fuel Cell Electrodes: Computational Parameters

Porous composite electrodes play a critical role in determining the performance and durability of solid oxide fuel cells (SOFCs) which are now emerging as a viable high efficiency, low emission energy conversion technology. This paper presented a modelling framework that simulates the synthetic three-dimensional microstructure of SOFC electrodes and their performance, linking to manufacture parameters such as the size of the particles and the size of the electrodes. For the first time, the boundary conditions and accuracy of the model were examined in relation to these manufacturing parameters. The results provide guidance on the required accuracy in characterizing SOFC electrodes.
