燃料电池汽车供氢新技术——硼氢化钠水解制氢

Hydrolysis of Sodium Borohydride for Supplying Pure Hydrogen to Fuel Cell Vehicle

常温下硼氢化钠可以稳定储存在碱溶液中,当与合适的催化剂接触时每摩尔硼氢化钠水解释放出4摩尔氢气。利用这一性质,硼氢化钠可以作为质子交换膜燃料电池的氢源。本文介绍了这种制氢技术的原理和特点,及其在燃料电池汽车上的应用和研究进展。

Sodium borohydride can be stored stably in alkaline solution at ambient conditions However, in the present of catalyst, one mol of NaBH4 can be hydrolyzed to liberate four mol of hydrogen Thus, the solution of sodium borohydride provides a fuel of high density of hydrogen for fuel cell vehicle In this paper, the principles and the characteristics of this hydrogen supply technology are introduced, and the application in fuel cell vehicle is reviewed
