Abstract: A hydrogen-purifying device is suitable for a fuel cell (FC). The hydrogen-purifying device includes a guiding tank, a first water-absorbing material, a porous filter material and a second water-absorbing material. The guiding tank is connected to a hydrogen-generating device and a fuel cell. The hydrogen-generating device generates hydrogen, moisture mixed with the hydrogen and impurities mixed with the hydrogen. The first water-absorbing material, the porous filter material and the second water-absorbing material are disposed in the guiding tank. The hydrogen passes through the first water-absorbing material to remove a part of the moisture. Then, the hydrogen further passes through the porous filter material to remove the impurity. After that, the hydrogen further passes through the second water-absorbing material to remove another part of the moisture and arrives at the fuel cell.

Abstract: A hydrogen production device includes a reaction unit and a hydrogen collection unit. The reaction unit includes a first region, a second region and a barrier layer. The first region stores a solid-state reactant, the second region stores a liquid-state reactant, and the barrier layer separates the first region from the second region. When the barrier layer forms an opening, the solid-state reactant comes into contact and reacts with the liquid-state reactant to produce hydrogen gas. The hydrogen collection unit has at least one gas vent to lead the hydrogen gas to flow into a hydrogen acceptor via the gas vent. The hydrogen gas is allowed to flow through the hydrogen collection unit, and the liquid-state reactant is prevented from entering the hydrogen collection unit.
