Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), unless expressly stated otherwise, may be replaced by other equivalent or alternative features serving a similar purpose. That is, unless expressly stated otherwise, each feature is but one example of a series of equivalent or similar features.

In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "central", "end" ”, “length”, “outer end”, etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying the indicated device or Elements must have a particular orientation, be constructed and operate in a particular orientation and are therefore not to be construed as limitations of the invention.

In addition, in the description of the present invention, "plurality" means at least two, such as two, three, etc., unless expressly and specifically defined otherwise.

Terms such as "upper," "upper," "lower," "lower," and the like used herein to indicate relative spatial positions are for ease of illustration to describe one element or feature as shown in the drawings relative to another A unit or feature relationship. The term spatially relative position may be intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or otherwise) and the spatially relative descriptors used herein interpreted accordingly

In the present invention, unless otherwise expressly specified and limited, the terms "arrangement", "socket connection", "connection", "penetration", "plug connection" and other terms should be understood in a broad sense, for example, it may be a fixed connection, It can also be detachable connection or integrated; it can be mechanical connection or electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal communication of two elements or the interaction of two elements relationship, unless otherwise expressly qualified. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

As shown in FIG. 1 and FIG. 2 , a water electrolysis hydrogen production device for a hydrogen generator of the present invention includes: a water tank 10, and more than one electrolysis device; the electrolysis device includes an end cover 1, a first gasket 2, Cathode electrode 3, second gasket 4, first breathable gasket 5, solid electrolyte 6, second breathable gasket 7, third gasket 8, anode electrode 9; both sides of water tank 10 are provided with through grooves 11;

The working process is as follows: a water electrolysis hydrogen production device for a hydrogen generator of the present invention provides an electrolysis water source to the electrolytic anode through the pores, and the electrolysis process relies on its own thermal energy to remove the circulating water from the pores, and the pores also undertake the discharge of oxygen gas. The outward-backward-upward movement and the hot-water upward movement are the same vector, which automatically circulates the water in the water tank in their respective directions.

The water entering the porous anode electrode 9 diffuses rapidly to the solid electrolyte 6 through the gas permeable pad 7 for electrolysis reaction. The hydrogen gas permeating the solid electrolyte 6 passes through the gas permeable membrane 5 and then the porous cathode electrode to reach the vent hole 12 designated by the end cap.
