摘　　要：以氨为燃料的固体氧化物燃料电池(SOFC)具有广阔的应用前景。对氨燃料SOFC——氧离子导电SOFC-O^(2-)和质子导电SOFC-H^(+)的电化学性能进行综述与评估,讨论不同电解质、电解质厚度及工作温度下氨燃料SOFC的最大功率密度。工作温度升高100℃,最大功率密度就会增加1~2倍;电解质越薄,电池性能越好。高温会造成电池热循环差、寿命短,因此亟需降低氨燃料SOFC的工作温度。为补偿降低温度造成的欧姆损失,需开发更薄、离子电导率更高的电解质。Ammonia-fueled solid oxide fuel cell(SOFC)had broad application prospects.The electrochemical performance of ammonia-fueled SOFC-oxygen ion-conducting SOFC-O^(2-)and proton-conducting SOFC-H^(+)were reviewed and evaluated.The maximum power density of ammonia fuel SOFC under different electrolyte,electrolyte thickness and working temperature was discussed.The maximum power density would increase by one to two times when the operating temperature increased by 100℃.The thinner of electrolyte,the better the battery performance.The high temperature would cause poor thermal cycle and low life of the battery,so it was urgent to reduce the working temperature of the ammonia fuel SOFC.In order to compensate for the Ohmic loss caused by temperature reduction,it was necessary to develop electrolytes with thinner and higher ionic electric conductivity.
