摘要
能源危机和环境污染是车载燃料电池发展的主要驱动力。电催化剂的性能和成本是制约其实现商业化的关键因素之一。目前,车载燃料电池用催化剂主要是铂(Pt)基催化剂,文章对质子交换膜燃料电池、直接甲醇燃料电池和甲酸燃料电池三种车载燃料电池用铂基催化剂的研究进行综述,并对其存在的问题进行了分析和讨论。
Energy crisis and environmental pollution are the main driving forces for the development of automotive fuel cell. However, the performance and cost of electrocatalyst become one of the key factors, which limit the large scale commercial application of fuel cells. So far, Pt-based catalysts have been mainly used for fuel cell. Three kinds of automotive fuel cell electrocatalysts for proton exchange membrane fuel cell, direct methanol fuel cell and formic acid fuel cell are discussed in detail, and their problems and solutions are analyzed.
