燃料电池电动汽车的技术难关和发展前景

本文在阐述了质子交换膜燃料电池上作原理的基础上,首先介绍了其质子交换膜与催化剂的研究现状。然后针对汽车领域的需要,给出了燃料电池发动机的概念,并对其燃料和氧化剂供给、水/热管理和控制等各子系统所要解决的技术难关进行了系统分析。同时对燃料电池车商业化所必然要涉及的氢燃料供给和价格等问题进行了较客观的论述。最后对燃料电池车的发展前景进行了预测,提出了相应的发展措施。

Technology Challenge and Prospect of Fuel Cell Vehicle

After expounding the working principles of the PEMFC, the research progress in proton exchange membrane and catalyst are introduced. According to transportation application, the conception of fuel cell engine is given in this paper. Then the technological challenges of its major subsystems such as fuel and oxidant supply subsystem, water/heat management and control subsystems are analyzed systematically, and the inevitable issues such as hydrogen supply and price in the process of fuel cell commercialization are objectively discussed. Finally, the market prospect and developing measures on fuel cell vehicles are given.
