NOVELTY - A reactor cover (100) in an apparatus for generating hydrogen by dissociating an electrolyte solution, comprises a base panel (110); a control unit (120) coupled to one side of the base panel and configured to regulate a reaction for generating the hydrogen; a circuit pattern (130) buried in the base panel in electrical connection with the control unit; and an electrode pad (140) formed on other side of the base panel in electrical connection with the circuit pattern.    USE - As a reactor cover useful in hydrogen generating apparatus for generating hydrogen by dissociating an electrolyte solution used in fuel cell power generation system (claimed); in polymer electrolyte membrane fuel cell membrane (PEMC) and direct methanol fuel cell (DMFC) useful for producing chemical energy of hydrogen generated at cathode to produce electrical energy.    ADVANTAGE - In the reactor cover, the base panel and the control unit can be integrated, to eliminate unnecessary wiring, prevent short-circuiting, and consequently provide a reactor cover that can be fabricated and used more easily.    DETAILED DESCRIPTION - A reactor cover (100) in an apparatus for generating hydrogen by dissociating an electrolyte solution, comprises a base panel (110); a control unit (120) coupled to one side of the base panel and configured to regulate a reaction for generating the hydrogen; a circuit pattern (130) buried in the base panel in electrical connection with the control unit; and an electrode pad (140) formed on other side of the base panel in electrical connection with the circuit pattern. In the reactor cover, a securing indentation is formed in one side of the base panel, and the control unit is inserted in the securing indentation. A thickness of the control unit is less than or equal to a depth of the securing indentation. The base panel includes at least one of a ceramic and a polymer. The electrode indentation is formed in the other side of the base panel, and the electrode pad is formed in the electrode indentation. A gold (Au) layer is formed on one surface of the electrode pad. The electrode pad is a socket configured to secure a conductive body to the base panel. The reactor cover further comprises a waterproof layer (150) formed on the other side of the base panel such that the electrode pad is exposed. The waterproof layer configured to prevent the electrolyte solution from penetrating into the base panel. INDEPENDENT CLAIMS are included for the following:    (1) a hydrogen generating apparatus for generating hydrogen by dissociating an electrolyte solution, comprising the reactor cover; an anode coupled to at least one of the electrode pads and configured to generate electrons; a cathode coupled to at least one of the others of the electrode pads and configured to receive the electrons from the anode to generate hydrogen; and a reactor having an opening and coupled with the base panel such that the anode and the cathode are held within the reactor; and    (2) a fuel cell power generation system for producing electrical energy using hydrogen generated by dissociating an electrolyte solution, comprising the hydrogen generating apparatus; and a fuel cell configured to convert chemical energy of the hydrogen generated at the cathode to the electrical energy.
