Problems solved by technology

[0002] At present, the research on solid oxide materials at home and abroad mainly focuses on testing its conductivity and AC impedance characteristics, ion or electron transfer number of solid oxide electrolyte materials, Seebeck coefficient (Seebeck effect) of solid materials, and oxygen permeability of solid oxides. Oxygen permeability test of membrane, charge and discharge performance test of solid oxide fuel cell single cell, and electrolysis experiment of solid oxide electrolytic cell, etc. Basically, it adopts an independent self-made test platform system, which is usually temporarily produced from local materials for the implementation of a specific performance test, or the platform produced by it can only provide a very small number of functional test purposes, and the function is single. Not well promoted

[0003] The reasons are as follows: 1. When the purpose or method of the experiment is changed, this kind of self-made platform device often involves the modification and reconstruction of the device platform, which is time-consuming and laborious, which is not conducive to the development of normal experiments and reduces the efficiency of scientific research; 2. Such self-made platform devices can usually only achieve a single performance test, that is, different performance tests of the same material need to use different platform systems, which can easily cause certain resources to be idle

3. The test platform devices built by different researchers usually have different shapes and structures due to their different ideas, and there are also differences in the level of test environment control. It is easy to cause problems when testing the same performance of the same material under the same conditions Due to the difference in data, experimental results based on the same reference standard cannot be provided, and even diametrically opposite conclusions can be drawn

[0004] At present, there is no test platform with independent intellectual property rights in China that integrates various basic solid oxide electrical and electrochemical performance test environments. Although a few platform devices with similar functions have entered the market abroad, their prices are high
