【摘要】：车用燃料电池主要包括质子交换膜燃料电池、金属-空气燃料电池等,其中质子交换膜燃料电池是目前车用燃料电池的主要开发对象(以下简称车用燃料电池)。经过全球范围内近十年的持续研发,车用燃料电池在能量效率、功率密度与比功率、低温启动等功能特性方面已经取得了突破性进展,新一轮的燃料电池汽车产业化浪潮正在迫近。然而,车用燃料电池的耐久性和成本还没达到预期商业化目标,是其产业化的最后障碍。探索和研发燃料电池用新型关键材料部件是解决这两大问题、推进其商业化进程的关键所在,也是车用燃料电池长期的研究重点和热点。本文系统地梳理了近几年来车用燃料电池质子交换膜、催化层、气体扩散层、双板板关键材料部件的研究进展和成果,并分类进行了简要评述,分析了其性能与商业化目标的差距。最后展望了车用燃料电池关键材料部件今后的发展方向。
[Abstract]:Vehicle fuel cell mainly includes proton exchange membrane fuel cell, metal-air fuel cell and so on, among which proton exchange membrane fuel cell is the main developing object of vehicle fuel cell (hereinafter referred to as vehicle fuel cell). After nearly a decade of continuous research and development around the world, vehicle fuel cells have made a breakthrough in energy efficiency, power density and specific power, low-temperature start-up and other functional characteristics. A new wave of fuel cell vehicle industrialization is approaching. However, the durability and cost of vehicle fuel cells have not reached the target of commercialization, which is the last obstacle to their industrialization. Exploring and developing new key material components for fuel cell is the key to solve these two problems and promote the commercialization of fuel cell. It is also the focus and hotspot of vehicle fuel cell research for a long time. In this paper, the progress and achievements of the research on the proton exchange membrane, catalytic layer, gas diffusion layer and biplate key material components of vehicle fuel cell in recent years are systematically reviewed. The gap between performance and commercialization target is analyzed. Finally, the future development direction of key material components of vehicle fuel cell is prospected.
