基于低温技术的汽车储氢系统研究综述

Review of On-Board Cryo-Hydrogen Storage System for Automotive

储氢系统是氢能汽车的关键分系统之一。在航天运载火箭液氢燃料成功应用的基础上,欧洲、美国、日本及中国都对液氢或低温高压氢气作为氢能汽车的储氢方式,开展过不同程度的研究工作,实现了多种技术路线的气瓶研制、供气系统开发、车辆集成、加注系统研制和行驶试验,并推出部分基于低温技术储氢的示范或定型车辆。文章对车载低温储氢供气整车、系统结构和工作模式、关键部件研制情况等进行了总结,并对相关车辆试验情况进行介绍。通过对比分析,提出了我国在汽车用低温储氢技术领域的研究方向。

:On-board hydrogen storage system is one of the key components for hydrogen-car.Based on the successful usage of liquid hydrogen fuel in aerospace launch vehicle,Europe,America,Japan and China had studied on the technology to use liquid hydrogen and cryogenic compressed hydrogen for ground vehicle on different levels.And they manufactured several types of liquid tanks,systems,cars,and refueling machines for hydrogen energy,and some of them have been tested on road.Some versions of cryogenic hydrogen cars have been launched to market and demonstrated around the world.The cryo-hydrogen fueled car,the structure of on-board cryo-hydrogen systems,working patterns,and key components were summarized,and some testing cases were overviewed.Some major research orientations were proposed for china after contrastive analysis.
