In AB5, A2B type hydrogen storage alloys, hydrogen is apt to enter into the crystal lattice place which surround the endothermic elements, so the functions of endothermic elements is enforce the absorbability towards hydrogen.

• 在AB_5、A_2B型储氢合金中，因为氢原子更倾向于进入吸热型元素周围的晶格位置，所以吸热型元素在储氢合金中起到了增强对氢原子吸附力的作用。
