NOVELTY - A static water supply proton exchange membrane brine electrolysis device comprises a static water supplying chamber, a semi-permeable membrane component, a hydrogen generating chamber, a reinforced membrane electrode component, and an oxygen generating chamber.    USE - A static water supply proton exchange membrane brine electrolysis device.    ADVANTAGE - The device does not need a water-gas separator. The generated gas is high-pressure gas that can reach to more than 14 MPa.    DETAILED DESCRIPTION - A static water supply proton exchange membrane brine electrolysis device comprises a static water supplying chamber, a semi-permeable membrane component, a hydrogen generating chamber, a reinforced membrane electrode component, and an oxygen generating chamber. Water in the static water supplying chamber passes through the semi-permeable membrane component under diffusion to reach the hydrogen generating chamber in water vapor form and diffuse to the reinforced membrane electrode component. The static water supplying chamber is a cavity and its interior is stored with normal pressure water while its top is provided with a water inlet, and its bottom is provided with a freeing port. The semi-permeable membrane component comprises left pressure-resisting supporting piece, left catalyzing layer, semi-permeable membrane, right catalyzing layer, and right pressure-resisting supporting piece. The left pressure-resisting supporting piece is connected with the static water supplying chamber. The right pressure-resisting supporting piece is connected with the hydrogen generating chamber. The left pressure-resisting supporting piece covers the left catalyst layer and reserved with a connection terminal for the outside for connecting with the positive pole of an external power. The left catalyzing layer is used for decomposing the hydrogen into hydrogen ion. The semi-permeable membrane allows water molecules and protons to pass through. The right catalyzing layer promotes the hydrogen ion to generate hydrogen. The right pressure-resisting supporting piece covers the right catalyzing layer and reserved with a connection terminal for the outside for connecting with the negative pole of an external power. The hydrogen generating chamber, the reinforced membrane component, the hydrogen generating chamber, and the semi-permeable membrane are jointed and connected by insulating layer and reserved with a hydrogen outlet to output the generated hydrogen. The reinforced membrane component comprises left membrane electrode supporting piece, common membrane electrode component, and right membrane electrode supporting piece. The left membrane electrode supporting piece and the right membrane electrode supporting piece are both reserved with connection terminals used for connecting the negative pole and the positive pole of the external power. Wall of the hydrogen generating chamber and the reinforced membrane electrode component are separated by insulating material and reserved with an oxygen outlet for outputting the generated oxygen.
