质子交换膜燃料电池不同流场的实验研究与优化
发布时间：2024-01-14 14:46
自21世纪以来,能源危机和环境污染日益严重。首先,随着全球工业的快速发展,煤、石油等传统燃料的消耗量不断加大。传统燃料燃烧将释放大量的SO2、CO、CO2和NO3气体,使得环境污染日益严重。全球气候变化和温室效应与CO2的排放息息相关,而其中超过一半的CO2排放来自化石燃料的燃烧。另外,化石燃料燃烧产生的SO2、NO3等有毒气体还将带来酸雨、臭氧层破坏以及海洋污染等一系列环境问题,危害社会的生存和发展。面对世界性的能源危机和环境污染,燃料电池作为一种清洁的能源转换装置,是当前很有前景的研究方向。燃料电池能通过电化学反应将燃料中的化学能直接并且连续地转换成电能,这是继水电、火电和核电之后的第四种发电方式。由于燃料不涉及过多的能量转换过程,其转换效率不受“卡诺循环”的限制,最高可达60%-80%,其实际使用效率是内燃机的2-3倍。同时,由于燃料电池整个运行过程中只会产生水,因此可以有效缓解环境污染。除此之外,由于燃料电池内部不涉及任何机械...
