摘要:
固体氧化物燃料电池(SOFC)是一种将燃料的化学能直接转换成电能的发电装置,其中流场均匀性对电池性能有显著影响,而连接体内部结构是决定流场均匀性的重要因素。采用数值模拟方法对连接体进行设计,以实现电池性能的最优化。研究结果表明:与普通连接体相比,添加泡沫Ni后,流场均匀性提高了15%以上。通过组合不同孔隙率的泡沫Ni,流场均匀度指数可达到95%以上,最大功率密度提高了11.4%。
Abstract:
Solid oxide fuel cell(SOFC)is a power generation device that converts chemical energy of fuel directly into electricity. Its flow field uniformity has a significant influence on battery performance. The internal structure of the connectome was one of the most important factors to determine the flow field uniformity. A new connectome structure was designed and a simulation was established for optimization design. The results showed that the flow field uniformity was increased by more than 15% after the addition of Ni foam. By combining foam Ni with different porosity, the flow field uniformity index can reach more than 95%, and the maximum power density is increased by 11.4%.
