Description

Technical Field

[0001] The invention relates to the technical field of membrane preparation, in particular to a preparation device for a doped and modified composite ceramic ion membrane element. Background Art

[0002] An ion membrane element is a membrane material element with the function of selectively permeating ions. It can allow specific ions to pass through under the action of driving forces such as electric fields or concentration differences, while preventing other ions or molecules from passing through. It is an efficient ion separation and conduction tool. In order to improve the performance of ion membrane elements, ceramic materials, dopants, binders and other materials are generally doped during the processing of ion membrane elements to improve the high temperature resistance, corrosion resistance and other properties of ion membrane elements. When processing ion membrane elements, it is generally necessary to accurately measure the required ceramic powder, dopants, binders and solvents from the raw material storage unit according to a predetermined formula, and put them into the mixing and stirring unit. In the stirring tank, the stirrer fully mixes the raw materials at a certain temperature and stirring speed to form a uniform mixed slurry. The mixed slurry is transported to the molding system and poured into the molding mold. A certain pressure is applied by the pressure molding equipment to form the slurry into the desired shape in the mold. The formed green body is transferred to the sintering system and placed in the sintering furnace to form a ceramic ion membrane with a specific microstructure and ion transmission performance.

[0003] The existing publication number is: CN1208862C. The present invention belongs to a method for preparing a proton exchange membrane fuel cell electrode. The catalyst, PTFE and a lower alcohol are mixed, dispersed with an ultrasonic generator and mechanically stirred for 0.5-30 minutes, and then transferred to carbon paper or carbon cloth in a template by a scraping method to prepare a proton exchange membrane fuel cell electrode, and then vacuum dried at 20-120°C for 2-24 hours, and then sintered at 150-350°C under air or argon protection for 0.5-2 hours, and then sprayed with Nafion stock solution on the surface, and then vacuum dried at 20-120°C for 2-24 hours. This method can not only effectively control the thickness of the electrode catalyst layer, the thickness of the catalyst layer can be greatly reduced and very uniform, but also can quickly and mass-produce large-area electrodes. It has high operability, rapid preparation process, simple and easy operation, no special equipment is required, and has good reproducibility.

[0004] However, when the formed green body is placed in a sintering furnace, in order to ensure the stability of the formed green body during sintering, the green body generally needs to be clamped and fixed. However, since the clamping parts are in contact with the fixed position of the green body for a long time, the green body is prone to uneven sintering heating during sintering, affecting the processing quality of the ion membrane.
