AI Technical Summary

Problems solved by technology

[0007] (1) Button solid oxide fuel cell loading, unloading and replacement are cumbersome

Some devices are sealed with glue at the interface of daily disassembly, resulting in the need for glue application, glue removal, drying and other processes during each loading and unloading, which is relatively cumbersome

[0008] (2) The cathode and anode chambers are large, and the sensitivity to gas components is poor

Due to the complex gas supply path and sealing structure, the cathode and anode chambers are often large, and the changes in cathode and anode gas components cannot be quickly reflected during the test.

[0009] (3) When the battery is running, the temperature outside the furnace of the reaction device is high, which is easy to burn or cause the sealing material to fail

The solid oxide fuel cell operates at a high temperature (600°C-1000°C). Due to heat transfer effects such as heat conduction and radiation, the temperature outside the furnace of the reaction device is relatively high, which puts higher requirements on sealing materials and is easy to burn the operator.
