氢能以其重量轻、热值高、无污染、来源丰富和应用面广等优点 ,被称为 2 1世纪的理想能源。美国已研制成功世界上第一辆以氢为燃料的汽车 ,可将 60 %～ 80 %的氢能转换成动能 ,其能量转换率比普通内燃机高一倍以上。氢能广泛应用的关键 ,在于研制出成本低的制氢技术。 1 989年 Hydrogen is known as the ideal energy source for the 21st century due to its advantages of light weight, high calorific value, no pollution, abundant sources and wide application. The United States has successfully developed the world’s first hydrogen-fueled car, which converts 60% to 80% of its hydrogen energy into kinetic energy and its energy conversion rate more than doubled that of conventional internal combustion engines. The key to the widespread use of hydrogen is the development of low-cost hydrogen production technologies. in 1989
