采用H和O迁移机制相结合的一维微观动力学模型模拟了Ni/YSZ图案化阳极三相界面附近的表面扩散、化学和电荷转移反应。在微动力学方案中对许多参数集进行了详尽的检查，以获得用于解释实验观察的适当参数集。我们找到了一组没有非物理拟合参数的参数，可以解释文献中报道的图案化阳极的大活度差距。从我们的模拟中我们发现，低活性的花纹阳极是由H和O跨越三相界面的迁移所控制的，而高活性的花纹阳极是由O的迁移所控制的。
A one-dimensional microkinetic model combining H and O migration mechanisms is used to simulate the surface diffusion, chemical and charge-transfer reactions near the triple phase boundary of the Ni/YSZ patterned anode. A number of parameter sets are exhaustively examined in the microkinetic schemes to obtain a proper set for the explanation of experimental observations. We find a set of parameters free from unphysical fitting parameters, and can explain a large activity gap of patterned anodes reported in literature. From our simulation, we found that the lower activity patterned anode is kinetically governed by both H and O migration across the triple phase boundary, while the higher activity patterned anodes are governed by the O migration.
