High temperature solid oxide fuel cell (SOFC) has prospect and potential to generate electricity from fossil fuels with high efficiency and very low greenhouse gas emissions as compared to traditional thermal power plants. In the last 10 years, there has been significant progress in the materials development and stack technologies in SOFC. The objective of this paper is to review the development of anode materials in SOFC from the viewpoint of materials microstructure and performance associated with the fabrication and optimization processes. Latest development and achievement in the Ni/Y2O3-ZrO2 (Ni/YSZ) cermet anodes, alternative and conducting oxide anodes and anode-supported substrate materials are presented. Challenges and research trends based on the fundamental understanding of the materials science and engineering for the anode development for the commercially viable SOFC technologies are discussed. 相似文献

Materials for lower temperature solid oxide fuel cells 总被引:5,自引:0,他引:5
The solid oxide fuel cell (SOFC) continues to show great promise for the generation of electricity for an increasing range of applications. The present SOFC technology is based on an all-ceramic design, which eliminates the corrosion problems associated with fuel cells containing liquid electrolytes. To obtain good electrochemical performance with the currently used materials, this all-ceramic fuel cell operates at 1000°C. Despite a significant amount of research and several successful demonstrations at the 100 kW level, commercialisation of the technology is not as rapid as anticipated. This is, in part, due to the high operating temperatures required, necessitating the use of expensive materials. As a result of these problems, there has been an effort over the past few years to lower the SOFC operating temperature. This paper will address the issues concerning the development of new materials that can operate at lower temperatures. Many of these issues have been or are being addressed in the research performed at Argonne National Laboratory, and some recent results will be discussed. 相似文献

Solid Oxide Fuel Cell:Materials, Technology and Application 总被引:1,自引:0,他引:1
Solid oxide fuel cells (SOFCs) offer a clean, pollution-free technology for the electrochemical conversion of chemical energy of hydrocarbon fuels into electricity. Many programs are being initiated in the United States, Europe, Japan and so on. The funding for SOFC development worldwide has risen dramatically and this trend is expected to continue for at least the next decades. These development programs are also investigating wider applications of SOFCs in stationary, residential, transportation and military sectors. Finally, it is summarized the key materials and fabrication processes of SOFC in this paper. 相似文献

Development of lanthanum strontium manganite perovskite cathode materials of solid oxide fuel cells: a review 总被引:1,自引:0,他引:1
San Ping Jiang 《Journal of Materials Science》2008,43(21):6799-6833
The high-temperature solid oxide fuel cell (SOFC) is the most efficient and environmentally friendly energy conversion technology
to generate electricity from fuels such as hydrogen and natural gas as compared to the traditional thermal power generation
plants. In the last 20–30 years, there has been significant progress in the materials development and stack technologies in
SOFC. Among the electrode materials, lanthanum strontium manganite (LSM) perovskites, till today, are the most investigated
and probably the most important electrode materials in SOFCs. The objective of this article is to review and update the development,
understanding, and achievements of the LSM-based materials in SOFC. The structure, nonstoichiometry, defect model, and in
particular the relation between the microstructure, their properties (electrical, thermal, mechanical, chemical, and interfacial),
and electrochemical performance and performance stability are critically reviewed. Finally, challenges and prospects of LSM-based
materials as cathodes for intermediate and low-temperature SOFCs are discussed. 相似文献
