摘　　要：介绍功能梯度电极的3种类型,即孔隙率分级、粒度分级和成分分级。着重分析功能梯度电极在提高固体氧化物燃料电池(SOFC)性能方面存在的潜力,并阐述功能梯度电极在SOFC中的应用。讨论3种分级类型在SOFC中的作用。功能梯度电极实验加工成本昂贵,且只能得到局部传输特性,可依据现有的模型建立SOFC计算流体动力学模型,分析功能梯度电极的影响,从而优化设计。最后,对功能梯度电极进行展望。Three types of functional gradient electrodes,namely porosity grading,particle size grading and composition grading were introduced.The potential of functional gradient electrodes in improving the performance of solid oxide fuel cell(SOFC)was mainly analyzed and the application of functional gradient electrodes in SOFC was described.The role of three grading types in SOFC were discussed.Since the experimental processing cost of functional gradient electrodes was expensive and only local transport characteristics could be obtained,SOFC computational fluid dynamics model based on the existing model was established to analyze the influence of functional gradient electrodes,so as to optimize the design.Finally,the functional gradient electrodes were prospected.
