[0018] Reference Figures 1 to 4 As shown, the utility model provides a highly efficient and stable catalyst carrier structure for electrolyzing water to produce hydrogen, comprising: a catalyst carrier column 1 and a water-to-hydrogen electrode body 2, wherein the water-to-hydrogen electrode body 2 is sleeved on the inner side of the catalyst carrier column 1.

[0019] A bearing groove 11 is opened inside the catalyst carrier column 1, and a pressing plate 4 is attached to the outer end wall of the bearing groove 11. The outer end of the pressing plate 4 is connected to a limiting push plate 3. The side of the limiting push plate 3 is connected to the catalyst carrier column 1 through a spring 31. An arc-shaped baffle 5 is inserted into the notch at the inner end of the bearing groove 11, and the lower end of the arc-shaped baffle 5 is connected to the lower cylinder surface of the catalyst carrier column 1 through a connecting stud 52.

[0020] First, the catalyst for hydrogen production by electrolysis of water is stored in the supporting groove 11 of the catalyst carrier column 1, and the catalyst carrier column 1 is sleeved on the water hydrogen production electrode body 2. The arc baffle 5 is pulled out downward, and the limiting push plate 3 pushes the pressing plate 4 to bring the catalyst in the supporting groove 11 into contact with the water hydrogen production electrode body 2 for reaction.

[0021] In this embodiment, the catalyst support column 1 has an annular inner portion with supporting grooves 11 , which are rectangular in shape. The surface of the catalyst support column 1 is provided with porous flow channels 12 , which are distributed between the supporting grooves 11 .

[0022] As a preferred embodiment, the carrier tank 11 is used to support the catalyst used for hydrogen production by water electrolysis. The catalyst carrier column 1 forms an integral catalyst carrier structure, facilitating efficient and stable catalyst loading, and preventing the catalyst from undergoing daily oxidation reactions with the outside air, which could affect the catalyst's activity. The circulation channel 12 facilitates the circulation of the electrolyte.

[0023] In this embodiment, the inner end of the limiting push plate 3 is connected to the outer end wall of the bearing groove 11, and the outer surface of the catalyst carrier cylinder 1 is connected to the spring 31. The side arc surface of the pressing plate 4 is bonded with a rubber pad 41, and the side arc surface of the arc baffle 5 is bonded with a sealing gasket 53.

[0024] In a preferred embodiment, spring 31 is in a stretched state. When arc-shaped baffle 5 is removed, limiting push plate 3 pushes pressure plate 4 to squeeze the catalyst in the groove out of the notch of support groove 11 and into contact with water-hydrogen electrode body 2, thereby accelerating the catalytic reaction and ensuring efficient and long-lasting contact between the catalyst in the support and water-hydrogen electrode body 2. The catalyst is stored between rubber pad 41 and sealing gasket 53, and its outer surface is coated with a porous material composed of metal ions and organic ligands. This porous material has a high specific surface area and an adjustable pore size.

[0025] In this embodiment, a fixed base plate 51 is welded to the lower end of the arc-shaped baffle 5, and the fixed base plate 51 is in contact with the lower surface of the catalyst carrier column 1. A connecting stud 52 is screwed to the surface of the fixed base plate 51.

[0026] As a preferred embodiment, the arc baffle 5 is plugged and fixed to the catalyst carrier column 1 through the fixed base plate 51 and the connecting stud 52 at the lower end, so as to prevent the catalyst in the blocking groove from contacting with the outside air, protect the activity of the unused catalyst in the catalyst carrier structure, and prevent the oxidation of the catalyst from affecting the efficiency of the catalytic reaction. The upper end of the arc baffle 5 is inserted into the interior of the catalyst carrier column 1 (not shown in the figure).

[0027] The efficient and stable catalyst carrier structure for hydrogen production from water electrolysis of the present invention can effectively solve the problem in the prior art that the catalyst carrier plate is difficult to efficiently contact with the electrodes in hydrogen production from water electrolysis, affecting the reaction efficiency. It ensures that the catalyst in the carrier efficiently and durably contacts the electrodes in hydrogen production from water electrolysis, accelerates the progress of the catalytic reaction, protects the activity of unused catalysts in the catalyst carrier structure, avoids catalyst oxidation affecting the catalytic reaction efficiency, and is suitable for efficient and stable catalyst carrier structures for hydrogen production from water electrolysis.
