Advanced SOFC technologies for low carbon, energy efficient and affordable power

传统的Ni-YSZ阳极在实际燃料环境下的耐久性方面存在局限性。目前正在研究的一些氧化物阳极，如圣安德鲁斯的LSCM系列材料，有望提供更好的碳沉积容忍度和更好的循环氧化还原稳定性。然而，将它们集成到IP-SOFC中必须考虑到它们较低的电子传导性以及不同的陶瓷工艺要求。这套方案的工作将寻求利用其他地方材料的持续进步，并将这些纳入IP-SOFC设计。在阳极方面，氧化物，如镧锶铬锰氧化物，提供了提高阳极抗硫和碳沉积的耐久性以及提高其在氧化还原循环中的稳定性的潜力。这将有利于提高堆栈的耐用性，并潜在地允许系统的重大简化。该项目将寻求将新的阳极材料应用到综合平面设计中，并寻找和开发用作阳极和阳极集电层的新替代材料。材料将通过固态技术和丝网印刷优化的工艺进行研究，以实现集成的平面模块，用于不同燃料的性能测试。对硫磺中毒和碳氢化合物裂解的敏感性将进行调查。

Conventional Ni-YSZ anodes have limitations with respect to their durability under real fuel environments. Some of the oxide anodes that are currently under investigation, such as the LSCM family of materials at St Andrews promise to give better tolerance to C-deposition and improved redox stability on cycling. However, their integration into the IP-SOFC has to take account of their lower electronic conductivity as well as the different ceramic processing requirements. Work in this package will seek to exploit the continuing advances in materials elsewhere and incorporate these in the IP-SOFC design. On the anode-side, oxides such as the lanthanum strontium chromite manganites, offer the potential to improve the durability of the anode towards sulphur and carbon-deposition and to improve its stability on redox cycling. This would have benefits in improving stack durability as well as potentially allowing a major simplification of the system. The project will seek to implement novel anode materials into the integrated planar design and to seek and develop new alternative materials for use as anodes and anodic current collection layers. Materials will be investigated by solid state techniques and processing optimised for screen printing to achieve integrated planar modules for performance testing in different fuels. Susceptibility to sulphur poisoning and hydrocarbon cracking will be investigated.
