Patent ID: 8303782

Claim:
A hydrogen generating apparatus comprising: a first hydrogen generating unit comprising a first electrode, the first electrode generating hydrogen by decomposing an electrolyte aqueous solution; a second hydrogen generating unit comprising a second electrode, the second electrode being placed adjacent to the first hydrogen generating unit, a super absorbent polymer formed on a surface of the second electrode, the super absorbent polymer being gelled when water is absorbed; a solution separation membrane interposed between the first hydrogen generating unit and the second hydrogen generating unit; a reactor accommodating the first hydrogen generating unit, the second hydrogen generating unit and the solution separation membrane; and a hydrogen vent being formed on one side of the reactor, the side of the reactor being adjacent to the second hydrogen generating unit, wherein the solution separation membrane allows the hydrogen to pass through and the electrolyte aqueous solution to be blocked such that the electrolyte aqueous solution is primarily prevented from escaping from the reactor, the super absorbent polymer is gelled by absorbing a portion of the electrolyte aqueous solution which is not blocked by the solution separation membrane and passes from the first hydrogen generating unit to the second hydrogen generating unit through the solution separation membrane such that the electrolyte aqueous solution is secondarily prevented from escaping from the reactor, and the second hydrogen generating unit generates the hydrogen by decomposing the portion of the electrolyte aqueous solution absorbed by the super absorbent polymer.
