贮氢合金与镍氢电池的有效应用贮氢合金在降低温度或提高压力时吸收氢气，相反在升高温度或降低压力时则放出氢气。当吸收氢气时发生放热反应，而在放出氢气时则发生吸热反应。因此，在吸氢过程中合金内部温升高达７００℃以上，而在放氢时则温降可至－１００℃。因为这样... Hydrogen storage alloys and nickel-metal hydride battery applications Hydrogen storage alloys in the lower temperature or increase pressure to absorb hydrogen, on the contrary, when the temperature is raised or the pressure is reduced when the release of hydrogen. An exothermic reaction occurs when hydrogen is absorbed, while an endothermic reaction occurs when hydrogen is released. As a result, the internal temperature rise of the alloy during hydrogen absorption is as high as 700 ° C, whereas the temperature drop during the hydrogen releasing can be as high as -100 ° C. because of this...
