氢储存是未来无污染燃料电池汽车的一项关键技术。目前美国密西西比州特洛伊市的能源转换装置公司(ECD)正在开发一种储氢新技术。这种先进储氢技术主要依赖一种按特殊形式排列的氢原子与金属原子结合形成的金属氢的加热与冷却。其过程为,金属合金制成松散的干粉末吸附充入储存容器的氢气,同时氢分子被分解为氢原子,并溶到该合金的结晶结构中去。当合金被加热时氢原子又被释放出来,还原为氢分子。去除热量可以促进氢原子的吸附。装有120kg 镁基金属氢粉末、体积为120L 的容器,能储存6kg 的氢气,可使燃料电池汽车连续行驶480km。
Hydrogen storage is one of the key technologies for future pollution-free fuel cell vehicles. At present, Energy Conversion Equipment Company (ECD) in Troy, Mississippi, is developing a new hydrogen storage technology. This advanced hydrogen storage technology relies mainly on the heating and cooling of a metal hydrogen formed by combining hydrogen atoms in a special form with metal atoms. The process is that the metal alloy is made into a loose dry powder to adsorb the hydrogen charged into the storage container, while the hydrogen molecules are decomposed into hydrogen atoms and dissolved into the crystal structure of the alloy. When the alloy is heated hydrogen atoms are released, reduced to hydrogen molecules. Removal of heat can promote the adsorption of hydrogen atoms. Equipped with 120kg magnesium-based metal hydrogen powder, a volume of 120L containers, can store 6kg of hydrogen, fuel cell vehicles can make continuous driving 480km.
