摘要
以燃料电池技术链为主线,叙述燃料电池关键材料与部件、电堆、系统存在的问题、发展现状与研究热点。关键材料包括催化剂、离子交换膜、气体扩散层;电堆关键部件包括膜电极组件、双极板等;系统部件包括空压机、增湿器、氢回流泵、氢瓶等。关键材料与部件的成本与耐久性是燃料电池汽车实现商业化的基础。中国燃料电池部分技术指标已经达到或超过全球同类商品的水平,需要鼓励产业大力投入,建立批量生产线,促进中国燃料电池技术进步。
In this paper, the state of the art of fuel cells for vehicles are reviewed. Based on the technology chain of vehicular fuel cells, the bottle-necks and research hot-points are elucidated in terms of materials, components and stacks. Particularly, the fuel cell materials include catalyst, ion exchange membrane and gas diffusion layer; the fuel cell components include membrane electrode assembly and bipolar plates; and the system components include air compressor, humidifier, hydrogen recirculation pump and hydrogen cylinder. Currently, some domestic FC materials have reached the standards of commercial products. The authors encourage industry partners to invest FC enterprises and build up relative production lines, promoting domestical FC technology progress.
