Abstract:
An absorbed hydrogen amount detecting method in a hydrogen absorbing tank, comprising steps of:a step for containing a hydrogen absorbing alloy powder of a predetermined amount in a hydrogen absorbing tank so that a hydrogen gas comes in the hydrogen absorbing tank from an external and goes out therefrom to the external, in the predetermined amount of the hydrogen absorbing alloy powder a contact condition between adjacent hydrogen absorbing alloy powders changing due to a volume expansion of the hydrogen absorbing alloy powder in occluding a hydrogen;a step for measuring an electrical resistance value between a pair of detect electrodes provided in the hydrogen absorbing tank; anda step for determining an absorbed hydrogen amount in the hydrogen absorbing tank based on a change of the electrical resistance value detected by said measure step.
