Oxygen-generating pump by solid electrolyte

The utility model relates to an oxygen-generating pump which uses solid electrolyte as materials, which comprises a ceramic pump body. The utility model is characterized in that the pump body is of cylindrical structure, two end openings around the pump body are respectively and fixedly provided with a zirconium oxide solid electrolyte sheet, the outer surface of the electrolyte sheet is coated with an air negative electrode of a manganous acid strontium lanthanum layer, and the inner part of the electrolyte sheet is coated with an oxygen positive electrode of a manganous acid strontium lanthanum layer. The oxygen positive electrode and the air negative electrode are respectively connected with the positive electrode and the negative electrode of a power supply through a leading out end of a meshy current conducting band, wherein, the meshy current conducting band, the oxygen positive electrode and the air negative electrode are compounded into an integral body, and the wall of the pump body is provided with an oxygen guiding pipe. The utility model has the advantages of simple and compact structure, small size, portability, high oxygen-generating purity, safe use, and good shock resistance.
