Deteriorates the coating material, and the deteriorated coating material and the conductor wire portion exposed in pure water through the gap between the coating materials are eluted as impurities in pure water, which impedes the purification of oxygen and hydrogen gas generated.

装置の給電機構。1. A solid electrolyte membrane is used as a diaphragm to separate an anode side and a cathode side, and pure water is electrolyzed by supplying voltage to positive and negative electrode plates while supplying pure water to the anode side. Then, in a hydrogen / oxygen generator composed of a hydrogen / oxygen generator in which a water electrolysis cell configured to generate oxygen gas from the anode side and hydrogen gas from the cathode side is housed in a pure water container, respectively. The hollow tube is electrically connected to the outer peripheral portion of the pure water container and the electrode plate of the water electrolysis cell in an electrically insulated state, and a power supply means for supplying a voltage to the water electrolysis cell is electrically connected to the hollow tube. The hollow tube is inserted in an insulated state at the same time to be electrically connected to the electrode plate at the same time, and the connecting portion between the power feeding means and the electrode plate is separated from the pure water in the pure water container. Power supply mechanism for hydrogen / oxygen generator.
