燃料电池车载氢气供给系统概述

Application of Hydrogen Supply System for Fuel Cell Vehicles

车载氢气供给系统是氢燃料电池车的关键分系统之一。本文介绍了车载氢气供给系统的工作原理和流程,分析了整个系统改进的四个方向即密封技术、气体调压稳压、管道洁净处理及提高氢气利用率;最后总结了车载氢气供给系统中影响这四个方向的关键元部件的选择。

Hydrogen supply system is a very important subsystem of fuel cell vehicles. In this paper the operational principles and process of the hydrogen supply system are introduced. Meanwhile,the four improvement directions of the whole system are analyzed,namely seal,pressure regulation and stabilization,pipeline cleanliness treatment and hydrogen utility improvement. Finally,the selection of key components that influence these four directions in the car hydrogen supply system is summarized.
