Power Supply Device

Abstract

A power supply device is provided. The power supply device includes a fuel cell, a hydrogen generator, a check valve and an exhaust valve. The fuel cell has a hydrogen inlet and a hydrogen outlet. The hydrogen generator is connected to the hydrogen inlet and used for generating hydrogen. The check valve is disposed in the hydrogen inlet and used for preventing the hydrogen within the fuel cell from flowing to the hydrogen generator, and preventing exterior air from entering the fuel cell. The exhaust valve is disposed in the hydrogen outlet for exhausting the hydrogen within the fuel cell.

What is claimed is: 
     
         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 first casing having a water inlet, a water outlet and a third opening, wherein the third opening is for connecting the hydrogen inlet; 
 a pump connected to the water inlet and the water outlet for pumping water into or drawing water from the first casing; and 
 a solid hydrogen fuel disposed in the first casing for performing hydrogen releasing reaction with water; 
   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.   
     
     
         2 . 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;   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,   wherein the fuel cell comprises a deoxidizer disposed in at least one of the fuel cell and the hydrogen generator.   
     
     
         3 . The power supply device according to  claim 2 , wherein the fuel cell further has a first through hole and a fourth connection portion located on the inner wall surface of the first through hole, and the fuel cell further comprises:
 a deoxidizing member having a hollow portion, a second through hole and a fifth connection portion, wherein the second through hole penetrates to the hollow portion from the outer wall surface of the deoxidizing member, and the fifth connection portion is located on the outer wall surface of the deoxidizing member for connecting the fourth connection portion;   wherein, the deoxidizer is disposed in the hollow portion.
