High-temperature solid oxide single electrolytic cell fixing test bracket

Abstract

A high-temperature solid oxide monomer electrolytic cell fixing test stand comprises a stainless steel flange, and a monomer electrolytic cell test fixing fixture and a monomer electrolytic cell test stand, which are disposed on the stainless steel flange, wherein, the electrolytic cell test fixing fixture includes a high-temperature stainless steel support plate, a high-temperature stainless steel pillar, a stainless steel nut, a polytetrafluoroethylene gasket, a spiral spring and a square stainless steel nut; and the monomer electrolytic cell test stand includes a high-temperature ceramic tube, a high-temperature ceramic ring, a monomer electrolytic cell sheet and a stainless steel sealed joint. The high-temperature solid oxide monomer electrolytic cell fixing test stand of the invention can be used for electrochemical performance test and evaluation of monomer electrolytic cell at high temperature and in the presence of different atmospheres. By combining ceramic material and high-temperature stainless steel material, the invention has the advantages of convenient operation, convenient assembly, flexible usage, etc.

Description

technical field [0001] The invention belongs to the field of electrochemical testing, in particular to a fixed testing bracket for a high-temperature solid oxide single electrolytic cell. Background technique [0002] The use of high-temperature solid oxide electrolysis cells to electrolyze water vapor to produce hydrogen is a hot research topic in the field of energy at present, and has broad development prospects. Accurate evaluation of electrolytic cell performance is of great significance to promote the development of high-temperature steam electrolysis hydrogen production technology. The test of electrolytic cell performance can be divided into single electrolytic cell test and electrolytic cell stack test. For laboratory research, single electrolytic cell test is the most commonly used. [0003] High-temperature solid oxide electrolytic cell testing generally involves high temperature, high humidity, and strong oxidizing or strong reducing atmosphere conditions. The r...

AI Technical Summary

Problems solved by technology

Since there is no fixing device in the sealing process, the success rate and stability of the sealing are not high, and problems such as air leakage are prone to occur

It has also been reported that the method of pressing heavy objects to fix the electrolyte sheet is used, but this method can only be used for vertical test devices, and the device is relatively complicated.
