摘要
介绍了5 kW氢—空质子交换膜燃料电池系统的基本组成原理,对该系统重要组成部分(包括反应气供给系统、水/热管理系统、控制及安全系统)进行了功能分析和系统设计。所设计的系统中,反应气供给系统由燃料(氢气)供给子系统及氧化剂(空气)供给子系统组成,水/热管理系统由加湿子系统及冷却子系统组成,并给出空气量、氢气量及加湿量的详细计算方法,为5 kW氢—空质子交换膜燃料电池系统设计提出适应性解决方案。
The principle of the 5 kW H2-air proton exchange membrane fuel cell (PEMFC) system is introduced, and functions and design methods of the key parts of the system, including the reactant gas feeding system, the water and thermal management system, the control system, and the safety system, are presented. In the designed system, the reactant gas feeding system consists of a fuel (hydrogen) feeding subsystem and an oxidant (air) feeding subsystem, while the water and thermal management system consists of a humidifying subsystem and a cooling subsystem. The de- tailed calculation methods of the volume of air and hydrogen as well as mass of humidifying are also given.
