氢气具有可燃性,氢气燃烧的生成物是水,没有污染,水分解又生成氢气。如此循环不息,能源源不断为人类提供能源。但是,氢气易挥发,难以贮存。科学家们发现,某些金属合金遇到氢气就像海绵吸水一样,在一定温度与压力下能吸收氢气形成氢化物,而当压力降到一定值后,氢化物又分解,把氢 Hydrogen gas is flammable. The product of hydrogen combustion is water. There is no pollution, and water decomposes to produce hydrogen. This endless cycle of energy sources continues to provide energy for humanity. However, hydrogen is volatile and difficult to store. Scientists have discovered that some metal alloys encounter hydrogen as a sponge absorbs water, and absorb hydrogen at certain temperatures and pressures to form hydrides. When the pressure drops to a certain value, the hydride decomposes again, and hydrogen
