Abstract

The invention discloses a composite electrolyte membrane for oxygen production. An active cathode layer and a cathode support layer are sequentially arranged on one side of an electrolyte layer from inside to outside, and an active anode layer and an anode support layer are sequentially arranged on the other side of the electrolyte layer from inside to outside, wherein the electrolyte layer is 5 to 50 mu m thick; the active cathode layer / active anode layer is 20 to 50 mu m thick; the cathode support layer / anode support layer is 40 to 120 mu m thick. According to the composite electrolyte membrane, a structural composition of the electrolyte membrane is optimized to endow the product with strong strength, low resistance and high reactivity, so that a technical bottleneck in the field of high-temperature oxygen permeating membranes is broken, and application fields of the electrolyte membrane are expanded; in addition, existing technical problems about sealing are effectively solved, and the product has the advantages of high yield and low cost, so that industrial application is facilitated.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite electrolyte membrane with a multilayer structure for oxygen production. Background technique [0002] Electrolyte membrane is an important solid material and has a wide range of applications in the field of electrochemistry. Among them, an important application field of oxygen ion conductor electrolyte membrane is solid oxide fuel cell (SOFC). As a core component, the electrolyte membrane has a key influence on the performance of SOFC, because the resistance of the electrolyte membrane causes ohmic polarization loss during energy conversion, and the electrolyte membrane structure needs to be ultra-thin to achieve the ideal conversion efficiency. Moreover, the operating temperature of SOFC is relatively high, and the theoretical operating temperature is 500-1000°C. Therefore, the practical application puts forward very high requirements on the composition ...
