Abstract:
1. A power supply device, comprising: a fuel cell having a hydrogen inlet and a hydrogen outlet; a hydrogen generator connected to the hydrogen inlet and used for generating hydrogen to enter the fuel cell, wherein the hydrogen generator comprises: a solid hydrogen fuel; an absorbent material carrying water for performing hydrogen releasing reaction with the solid hydrogen fuel; a first casing having a first opening and a third opening, wherein the third opening is for connecting the hydrogen inlet, and the solid hydrogen fuel is disposed in the first casing; and a second casing having a second opening, wherein the absorbent material is disposed in the second casing, the inner diameter of the second opening is larger than the outer diameter of the solid hydrogen fuel, and the outer diameter of the second casing is smaller than the inner diameter of the first opening, so that after the second casing enters the first casing through the first opening, the absorbent material and the solid hydrogen fuel come into contact for generating hydrogen; a check valve disposed in the hydrogen inlet for avoiding the hydrogen within the fuel cell from being exhausted from the hydrogen inlet; and an exhaust valve disposed in the hydrogen outlet for exhausting the hydrogen within the fuel cell.
