NOVELTY - The apparatus (100) for generating hydrogen by dissociating an electrolyte solution (115), comprises an electrolyte bath (110) having an outlet and containing the electrolyte solution, an anode (120) coupled to the electrolyte bath and configured to generate electrons, a cathode (130) coupled to the electrolyte bath and configured to receive the electrons from the anode to generate hydrogen, a filter to cover the outlet of the bath and filter out foreign substances carried in the hydrogen, a pressure sensor coupled inside the electrolyte bath, and a control unit.    USE - The apparatus is useful for generating hydrogen by dissociating an electrolyte solution and is useful in a fuel cell power generation system for producing electrical energy (claimed).    ADVANTAGE - The apparatus is capable of efficiently and rapidly generating the pure hydrogen by dissociating the electrolyte solution without the risk of the electrolyte bath bursting and without creating a risk of safety hazards due to the increases in internal pressure inside the electrolyte bath.    DETAILED DESCRIPTION - The apparatus (100) for generating hydrogen by dissociating an electrolyte solution (115), comprises an electrolyte bath (110) having an outlet and containing the electrolyte solution, an anode (120) coupled to the electrolyte bath and configured to generate electrons, a cathode (130) coupled to the electrolyte bath and configured to receive the electrons from the anode to generate hydrogen, a filter to cover the outlet of the bath and filter out foreign substances carried in the hydrogen, a pressure sensor coupled inside the electrolyte bath, a control unit electrically connected with the anode and the cathode, and a sealing material covering the pressure sensor to prevent the penetration of the electrolyte solution. The control unit is configured to control a flow of electricity between the anode and the cathode in response to the output signal. The pressure sensor is configured to sense a pressure inside the electrolyte bath and to generate an output signal corresponding to the pressure. The sealing material is made of a flexible material. If the pressure inside the electrolyte bath exceeds a particular value, the pressure sensor generates a break signal as the output signal and transfers the break signal to the control unit and the control unit breaks the flow of electricity between the anode and the cathode in response to the break signal. If the pressure inside the electrolyte bath falls below a particular value, the pressure sensor generates an operate signal as the output signal and transfers the operate signal to the control unit and the control unit enables the flow of electricity between the anode and the cathode in response to the operate signal.
