A substance for reversibly sorbing and desorbing hydrogen is disclosed. The substance comprises a complex dispersing 0.8-20% by weight of one or more than two oxides selected from La, Ce, Nd, Pr, Sm and Eu into ZrV.sub.x (0.01.ltoreq.x.ltoreq.0.7).
摘要:
A fuel cell system has a fuel cell of solid polymer type, a rectangular parallelepiped sealing container for accommodating hydrogen occlusion alloy for occluding hydrogen to be supplied to said fuel cell, a connection portion provided in a hydrogen passage between said sealing container and said fuel cell for connecting said sealing container and said fuel cell detachably, a valve mechanism provided in said hydrogen passage for opening and shutting hydrogen gas, and a hydrogen flow rate control mechanism provided in said hydrogen passage for controlling the flow rate of hydrogen gas, and/or hydrogen pressure control mechanism for controlling the pressure of hydrogen gas.
