SOFC/SOEC button battery testing fixture

The SOFC/SOEC button battery testing fixture uses all ceramic materials and utilizes ceramic springs to maintain stable elastic force performance from room temperature to high temperature, achieving sealing of the fixture and simplifying the installation and operation of previous external pressure methods. Adopting an independent configuration of voltage and current lines to reduce sampling bias caused by voltage drop during testing.

Electric furnace/battery fixture unit:

The fixture is made of all ceramic material, utilizing the stable elastic force of ceramic springs from room temperature to high temperature, achieving sealing of the fixture and simplifying the installation and operation of previous external pressure methods. Adopting a voltage current line configuration to reduce sampling bias caused by voltage drop during testing.

The electric furnace is equipped with a built-in temperature probe for temperature control and supports multi-stage program control. The fixture anode is equipped with a temperature probe, which can provide accurate feedback on the actual temperature of the single cell.
Electric furnace temperature control method: multi-stage programmable control temperature curve; Fixture size: Supports fixture customization and can be adapted to square/button batteries; Pressure method: ceramic spring.

Control system:

The system is controlled and displayed using a touch screen, and users only need to operate on the touch screen to control the SOFC testing system.

It has the functions of gas flow control, temperature control, electronic load instrument control, and data recording, displaying temperature, gas flow rate, voltage, current, and power in real time, and can export data through a USB flash drive for deep application.

Security protection system:

The system is equipped with functions such as temperature alarm, low water level alarm, gas leakage alarm, etc., which can be displayed and prompted on the touch screen. Simultaneously supporting external signal input for fault linkage shutdown and other functions, cutting off load output and gas in emergency situations.

The hydrogen leak detection unit adopts an electrochemical sensor, which can promptly issue an alarm signal at low concentrations. The temperature protection function supports local settings and can adjust the over temperature protection value, over temperature difference protection value, etc. for different operating conditions.
