Description

一种中冷加湿装置及其应用的燃料电池系统 技术领域：
本发明涉及一种中冷加湿装置及其应用的燃料电池系统。
背景技术：
燃料电池系统中包括三大管路系统分别为空气进气系统、冷却系统、供氢系统。燃料电池系统正常工作时，通常采用空压机将空气增压压缩后，送入空气进气系统。经过空压机压缩后的空气温度可达120℃左右，过高的温度可能导致系统故障，甚至损坏燃料电池的电堆。送入电堆的空气必须保持在60-70℃的湿润空气，电堆才能正常稳定的运行，所以必须对送入电堆的空气进行冷却和加湿。以往需要利用中冷器将送入的高温空气进行冷却，冷却至60-70℃，之后再通过加湿器加湿后送入电堆中使用，且通过电堆出口的湿润气体再回送至加湿器对中冷器冷却的干燥空气进行加湿，加湿后的干燥空气送入电堆使用。
目前的燃料电池的空气进气系统都布置独立的中冷器和加湿器，例如专利CN 210467989 U中，独立布置的中冷器和加湿器，需要很多管路去相互连接，并且布置复杂、占用空间，造成管道流阻增大，增加系统风险。
另外现有为了解决占用空间大问题，将中冷模块安装在加湿模块的一侧，空气从空气从中冷模块一侧进入中冷模块中冷却，再从加湿模块一侧进入加湿模块中加湿，中冷模块与加湿模块接触面积小，通过气流小，效率低，长度较长。
