NOVELTY - The brown gas generator has cell plates (20) which are spaced apart at preset intervals from each other and provided with electrode connecting portion for connecting to an anode or a cathode, such that anode and cathode is used alternately. Fixed terminals (40) are placed in water of an electrolyzer for securing the cell plates in spaced-apart state. Parallel electrodes (50) are individually joined to the electrode connecting portion to which positive and negative power source is applied by power source cables (60).    USE - Brown gas generator for electrolyzing water and for generating hydrogen gas and oxygen gas.    ADVANTAGE - Water can be electrolyzed easily using small amount of current and the gap between cell plates can be reduced as the amount of oxygen gas and hydrogen gas can be enlarged and sides of the cell plate water is electrolyzed. The cell plate is easily inserted into the fixed terminal and hydrogen gas quantities can be increased and decreased, so that the sensitization of the hydrogen gas generation amount can be facilitated and installation fee of the brown gas generator can be reduced. The need for additional configuration of brown gas generator for voltage drop can be avoided and loss of electricity can be prevented. The cooling efficiency can be increased and unnecessary element can be removed, so that generated heat can be rapidly discharged outside. The contamination of water filled with the electrolyzer due to oxidation and corrosion can be prevented. Convenience can be improved and the electrolyzer can be used for long time without the need to exchange the water filled with the electrolyzer. The generation rate of the hydrogen gas can be maintained regularly and hydrogen gas can be supplied steadily.
