  • Oxygen-hydrogen electrolytic gas generation apparatus
    Patent number: 5667647
    Abstract: An oxygen-hydrogen gas generation apparatus in which an ion exchange film is used to prevent oxygen and hydrogen from mixing. The oxygen-hydrogen gas generation apparatus includes an electrolytic cell. The electrolytic cell includes an ion exchange film interposed between box-shaped structures. The box-shaped structures each have an interior surface coated with metal, a framework for holding the ion exchange film, and a gas discharge port. Oxygen gas is generated in a chamber formed by the ion exchange film and the box-shaped structures connected to a positive pole of a power supply. A hydrogen gas is generated in a chamber formed by the ion exchange film and the box-shaped structures connected to a negative pole of the power supply.
