中文摘要：
提出一种电极/电解质一体化的、催化剂粒子纳米化的固体氧化物燃料电池（SOFC）的电极新结构，并用浸渍法研制了这种一体化电极，优化了制备条件，阐述了纳米催化剂的形成过程，得到了电化学活性高、热循环稳定性好的一体化阴极和阳极，此外，这种阳极还具有良好的抗积碳性能。针对SOFC电极结构特点，提出了二维无穷大体系的渗流理论，发展了SOFC电极的普适性理论，即适用于各种电极结构的粒子层模型，形成了电极热循环稳定性的力学/电化学模型，给出了电极的界面极化比电阻、三相界面长度与孔隙率、厚度、粒子大小与分布、电极构型等的函数关系，并从理论上证明，与传统复合电极相比，一体化电极具有更好的电化学活性和热循环稳定性。提出了一类高性能的阴极新材料，即以掺杂氧化铋为氧离子导体、锰酸锶镧为电子导体的氧化物阴极，发现了一种基于镧系氧化物的不含氧离子导体的复合阳极，并给出其阳极机理。发展了一种高性能玻璃封接材料，并提出密封的力学模型。上述材料及其理论，不仅在SOFC电堆中得到成功应用，还成为"973"SOFC的立项基础，同时发表SCI论文83篇，专利5项，专著1章，培养博士研究生13名、硕士研究生7名。
