<P>PROBLEM TO BE SOLVED: To provide an alkaline water electrolytic apparatus that is facilitated in removing bubbles from an electrolytic solution, and to provide an alkaline water electrolytic method. <P>SOLUTION: The alkaline water electrolytic apparatus includes: an anode chamber 20 in which an anode 25 is disposed; a cathode chamber 30 in which a cathode 35 is disposed; a diaphragm 40 for partitioning between the anode chamber 20 and the cathode chamber 30; and an electrolytic bath 10 for electrolyzing the electrolytic solution 80 to produce hydrogen 78. The electrolytic bath 10 is configured such that the electrolytic solution 80 is introduced from a bottom introduction part 26 of the anode chamber 20 and flows upward through the anode chamber 20 toward a top discharging part 28, and the electrolytic solution 80 is introduced from a bottom introduction part 36 of the cathode chamber 30 and flows upward through the cathode chamber 30 toward a top discharging part 38. The electrolytic solution 80 has a pH of 14 or more measured at 27°C, an electrical conductivity of 0.25 S/cm or more measured at 27°C and a density of 1.25 kg/m<SP POS="POST">3</SP>or more. <P>COPYRIGHT: (C)2013,JPO&INPIT |
