Patent ID: 8372551

Claim:
A hydrogen generating apparatus comprising: an electrolyte bath containing an electrolyte solution; a first electrode, stacked on a surface inside the electrolyte bath and configured to generate electrons, oxidized in the electrolyte solution so as to release the electrons; a first moisture absorption layer, made of a porous material and being in direct contact with the first electrode, stacked on the first electrode and configured to absorb moisture from the electrolyte solution; and a second electrode having a thickness of 10 to 50 μm, in direct contact with the first moisture absorption layer, stacked on the first moisture absorption layer and configured to generate hydrogen using the electrons and the electrolyte solution, the second electrode receiving the electrons which travel from the first electrode so as to react with the electrolyte solution and generate the hydrogen, the first electrode being made of a metal having a greater tendency to ionize than material used for the second electrode, the first electrode, the first moisture absorption layer, and the second electrode being thin film layers, and the first electrode and the first moisture absorption layer having thicknesses of 10 to 100 μm, respectively.
