NOVELTY - An apparatus (260) for generating hydrogen by dissociating an electrolyte solution (235), comprises an electrolyte bath (230) containing the electrolyte solution; an anode (210) positioned inside the electrolyte bath and configured to generate electrons; a cathode (220) positioned inside the electrolyte bath and configured to receive the electrons from the anode to generate hydrogen; and a supplementary device configured to increase an amount of the hydrogen generated.    USE - As an apparatus for generating hydrogen useful in fuel cell power generation system for producing electrical energy (claimed), for processes of burning fuel, generating vapor, driving turbines, and driving power generators; in fuel cell including polymer electrolyte membrane fuel cell (PEMFC) and direct methanol fuel cell (DMFC) for applications to portable electronic devices.    ADVANTAGE - The apparatus can be utilized to increase the amount of hydrogen generation at initial operation and reduce the time required to reach steady state at initial operation for hydrogen generation. By using the supplementary cell that can be electrically connected between the anode and cathode, the amount of hydrogen generated during initial operation can be increased, and therefore the time required to reach steady state can be reduced. As a result, the hydrogen generating apparatus is capable of generating hydrogen more quickly and has improved initial response properties.
