NOVELTY - The apparatus (100) has a main portion (110) which is provided with water inlet (111) and water outlet (112). The anode (120a) and cathode (120b) are arranged at regular intervals. The ion exchange membrane (130) is installed at the main portion, so as to dissociate the water containing high concentration of dissolved hydrogen and to transmit the water to inlet portion. The dissociated water is discharged to the outside by the water outlet portion. The insulating film (150) is provided between the cathode and anode. The ion exchange resin (140) is filled between cathode and anode.    USE - Apparatus for generating high concentration hydrogen containing electrolyzed functional water used as drinking water.    ADVANTAGE - The purity of hydrogen can be improved by controlling the reaction of hydrogen ion and nitrogen ion. The various types of harmful ions generated when generating functional water can be removed effectively, through ion exchange with an ion exchange filter, so as to inhibit the reaction with hydrogen ions or hydrogen gas. Hence the deterioration of the purity of hydrogen contained in functional water can be prevented. The stable functional water can be generated. The nitrogen ions or ammonium ions contained in functional water can be removed through ion exchange before functional water is stored in a water tank, so that the generation of unpleasant odor can be prevented. The removal effect of harmful ions can be improved without the change in pH by manufacturing an ion exchange resin. The performance of the functional water generating apparatus can be improved. The customer satisfaction about the functional water can be improved. The quality of the functional water can be improved by removing the unnecessary ions.
