Hydrogen generator

A hydrogen generator comprising:

• an electrolytic cell;
• a hydrogen tank;
• an oxygen tank;
• an anion exchange membrane that divides the electrolytic cell into a cathode chamber and an anode chamber;
• a cathode chamber water supply part that supplies a first water to the cathode chamber by circulating between the hydrogen tank and the cathode chamber;
• an anode chamber water supply part that supplies a second water that is a water in a different system from that of the first water to the anode chamber by circulating between the oxygen tank and the anode chamber;
• a cathode that is provided on a cathode chamber-side surface of the anion exchange membrane;
• an anode that is provided on an anode chamber-side surface of the anion exchange membrane;
• a cathode feeder that is arranged within the cathode chamber and feeds power to the cathode;
• an anode feeder that is arranged within the anode chamber and feeds power to the anode;
• an active oxygen reduction material that reduces active oxygen generated within the anode chamber by hydroxide ions that move from the cathode chamber to the anode chamber passing through the anion exchange membrane;
• and
• a pressure adjusting part that makes an internal pressure of the cathode chamber equal to or higher than an internal pressure of the anode chamber,
• wherein the first water is maintained completely separate from the second water.
