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.
Abstract:
 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 studied
the effects of microstructure parameters such as thickness of K/Pt/Al2O3 adsorption layer and porosity of NiO/YSZ
electrode on NO electrochemical performance.Results show that NO conversion and current efficiency decrease with
the increase of thickness of K/Pt/Al2O3 adsorption layer and porosity of NiO/YSZ electrode in DC electrolysis.And
variations become significant at low O2 concentrations.In AC electrolysis,NO conversion decreases with the increase
of thickness of K/Pt/Al2O3 adsorption layer and the decrease of porosity of NiO/YSZ electrode.
