Abstract

A hydrogen-generating device is provided, which includes a reaction tank, a first cap, a second cap and a first guiding-pipe. The reaction tank has an accommodation space for accommodating a solid reactant. The first cap covers the accommodation space, wherein the first cap has a plurality of first open-holes. The second cap is disposed on the first cap and has a second open-hole, wherein the first cap and the second cap form a chamber therebetween. The first guiding-pipe passes through the first cap and the second cap to extend to the accommodation space, wherein the first open-holes surround the first guiding-pipe. A liquid reactant is for passing through the first guiding-pipe to arrive in the accommodation space and reacts with the solid reactant to generate a hydrogen. The hydrogen passes through the first open-holes to arrive at the chamber and then is expelled from the second open-hole.

Claims

a first cap, covering the accommodation space, wherein the first cap has a plurality of first open-holes;

a second cap, disposed on the first cap and having a second open-hole, wherein the first cap and the second cap form a chamber therebetween; and

a first guiding-pipe, passing through the first cap and the second cap to extend to the accommodation space, wherein the first open-holes surround the first guiding-pipe, a liquid reactant is capable of passing through the first guiding-pipe to arrive in the accommodation space and reacts with the solid reactant to generate a hydrogen, and the hydrogen passes through the first open-holes to arrive at the chamber and is expelled from the second open-hole.

2. The hydrogen-generating device as claimed in claim 1, wherein the first cap has a plurality of baffles and the baffles extend to the chamber.

3. The hydrogen-generating device as claimed in claim 2, wherein the first open-holes surround the baffles.

4. The hydrogen-generating device as claimed in claim 2, wherein the baffles are a plurality of concentric-circle structures and surround the second open-hole.

5. The hydrogen-generating device as claimed in claim 2, wherein each of the baffles has a plurality of notches and the hydrogen passes through the notches to cross each of the baffles.

6. The hydrogen-generating device as claimed in claim 1, further comprising a filter component, wherein the filter component is disposed in the chamber and the hydrogen passes through the filter component to arrive at the second open-hole.

7. The hydrogen-generating device as claimed in claim 1, wherein the first guiding-pipe passes through the second cap via the second open-hole.

8. The hydrogen-generating device as claimed in claim 1, wherein the second cap further has a third open-hole and the first guiding-pipe passes through the second cap via the third open-hole.

9. The hydrogen-generating device as claimed in claim 1, further comprising a hollow pipe fixed at the reaction tank and located in the accommodation space, wherein the first guiding-pipe extends to the hollow pipe, a wall of the hollow pipe has a plurality of holes, the holes respectively face different areas of the accommodation space and the liquid reactant passes through the holes to arrive in the accommodation space.

10. The hydrogen-generating device as claimed in claim 1, further comprising a water tank for accommodating the liquid reactant, wherein the first guiding-pipe is communicated with the water tank and the liquid reactant is guided from the water tank to the reaction tank through the first guiding-pipe.

11. The hydrogen-generating device as claimed in claim 10, further comprising a second guiding-pipe communicated with the second open-hole and extending to the water tank, wherein the hydrogen passes through the second guiding-pipe and arrives in the water tank from the reaction tank, and the liquid reactant in the water tank is used to cool the hydrogen down.

12. The hydrogen-generating device as claimed in claim 11, wherein an outlet of the second guiding-pipe has a web component and the hydrogen passes through the web component to arrive in the water tank.

13. The hydrogen-generating device as claimed in claim 11, wherein a moisture passes through the second guiding-pipe to arrive in the water tank from the chamber and is solved in the liquid reactant.

14. The hydrogen-generating device as claimed in claim 11, wherein the water tank has an exhaust, and the hydrogen in the water tank passes through the exhaust to be guided to a fuel cell stack.

15. The hydrogen-generating device as claimed in claim 14, wherein the water tank has a plurality of partition-boards to form a tortuous channel, and the hydrogen passes through the tortuous channel to arrive at the exhaust.
