摘 要目前人类社会正面临着全球性能源枯竭与环境恶化日益严重的双重压力，改变传统能源利用方式已迫在眉睫。因此我们需要寻求新型的优质能源并研制出先进的能源利用技术，并完成能源利用方式的转型，已是刻不容缓。固体氧化物燃料电池（SOFC）具有零排放、低噪音、燃料多样化、可靠性高及适用范围广等优点，被认为是21世纪最为绿色环保的重要的发电技术之一。

第一章主要介绍了燃料电池的简史及工作原理、燃料电池的分类、SOFC的工作原理及分类及国内外的研究现状。87046

第二章主要是介绍了SOFC的阳极、电解质与阴极的材料的性能要求以及介绍了阳极、电解质与阴极常用的材料。

第三章介绍了微管SOFC二维轴对称模型，应力、应变、以及损伤几率计算方法，并对计算结果进行了验证。

第四章分析了三种不同材料电池（阳极/电解质/阴极），电池A(Ni-3YSZ/3YSZ/LSM-3YSZ)、电池B(Ni-8YSZ/8YSZ/LSM-8YSZ)、电池C(Ni-GDC/GDC/GDC-LSCF)对电池残余应力及其损伤几率的影响。发现电解质与阴极损伤几率可以忽略不计，从阳极损伤几率的影响考虑，电池B表现得最为优异，其次是电池A，再次是电池C。

结论部分对全文进行了总结。

Abstract At present human society is facing a global energy depletion and environmental degradation growing dual pressures to change the traditional energy use is imminent。 So we need to find new energy and high-developed advanced energy technologies, and to complete the transition energy use patterns, it is imperative。 The solid oxide fuel cell (SOFC) has zero emissions, low noise, fuel persification, high reliability and a wide range of advantages, is considered one of the most important green power generation technology in the 21st century。

The first chapter introduces the brief history of the working principle of the fuel cell, the fuel cell SOFC works classification and research status, and classification and abroad。

The second chapter is to introduce the performance requirements of SOFC anode, electrolyte and cathode material and the introduction of an anode, electrolyte and cathode materials commonly used。

The third chapter introduces the model, stress, strain, and the calculation of the probability of damage microtubules SOFC axisymmetric, and the results are verified。

The fourth chapter analyzes the three different battery materials (anode / electrolyte / cathode), Battery A (Ni-3YSZ / 3YSZ / LSM-3YSZ), Battery B (Ni-8YSZ / 8YSZ / LSM-8YSZ), Battery C (Ni -GDC / GDC / GDC-LSCF) on the battery residual stress and the chance of injury。 Electrolyte and cathode was found negligible chance of injury, damage probability from the anode to consider the impact of the battery B was most excellent, followed by a battery A, the battery is again C。

The conclusion of the full text of the summary。

Key words: micro-tubular SOFC; stress; damage probability;
