中文摘要：

建立了一维轴对称交直流电解NO的数学模型，并基于Butler-Volmer动力学方程估计了NO电化学反应动力学参数，研究了K/Pt/Al2O3吸附层厚度、NiO/YSZ电极孔隙率等结构参数对于NO交直流电解反应特性的影响规律，计算结果表明：直流电解NO的转化率和电流效率随着吸附层厚度的增加和NiO/YSZ电极孔隙率的增加而降低，低O2体积分数的条件下变化较为明显；低的吸附层厚度和高的NiO/YSZ电极孔隙率有利于获得较高的交流电解NO转化特性．

英文摘要：

A one-dimensional model for NO alternative current(AC)and direct current(DC)electrolysis was developed.The NO electrochemical reaction kinetics parameters were estimated based on Butler-Volmer.This paper studiedthe effects of microstructure parameters such as thickness of K/Pt/Al2O3adsorption layer and porosity of NiO/YSZelectrode on NO electrochemical performance.Results show that NO conversion and current efficiency decrease withthe increase of thickness of K/Pt/Al2O3adsorption layer and porosity of NiO/YSZ electrode in DC electrolysis.Andvariations become significant at low O2concentrations.In AC electrolysis,NO conversion decreases with the increaseof thickness of K/Pt/Al2O3adsorption layer and the decrease of porosity of NiO/YSZ electrode.
