A hydrogen generator includes a water tank adapted to form a water chamber, and a water electrolysis cell disposed in the water tank. The water electrolysis cell includes a proton conductive membrane, an oxygen generator chamber side separator adapted to form an oxygen generator chamber, and a hydrogen generator chamber side separator adapted to form a hydrogen generator chamber, and a hydrogen outlet passage adapted to discharge generated hydrogen out of the hydrogen generator chamber. The oxygen generator chamber side separator includes a communicator passage adapted to communicate the oxygen generator chamber with the water chamber. The hydrogen generator obviates the manifolds of the conventional hydrogen generators in which the generated oxygen is likely to stagnate and hinder the water supply, and accordingly it can inhibit the hydrogen gas generating capability from deteriorating.

A hydrogen generator, comprising: a water tank forming a water chamber therein; and a water electrolysis cell disposed in said water tank, and including; a proton conductive membrane; an oxygen generator chamber side separator disposed on one side of said proton conductive membrane, said oxygen generator chamber side separator is formed in a ring shape having an inner peripheral surface and an outer peripheral surface, the inner peripheral surface defining an oxygen generator chamber, said oxygen generator chamber side separator including a communicator passage communicating the oxygen generator chamber with said water chamber, the communicator passage extending from the inner peripheral surface toward the outer peripheral surface to thereby discharge unreacted water and generated oxygen from the oxygen generator chamber; a hydrogen generator chamber side separator disposed on another side of said proton conductive membrane, said hydrogen generator chamber side separator is formed in a ring shape having an inner peripheral surface and an outer peripheral surface, the inner peripheral surface defining a hydrogen generator chamber; and a hydrogen outlet passage including a main outlet passage penetrating through said hydrogen generator chamber side separator in a thickness-wise direction thereof and an auxiliary outlet passage connecting the main outlet passage with said inner peripheral surface of said hydrogen generator chamber side separator to thereby discharge unreacted water and generated hydrogen from said hydrogen generator chamber to the water chamber. The hydrogen generator according to claim 1 including a plurality of said water electrolysis cells stacked together.
