Evaluation and deterioration test of SOFC flat plate single cell
BEL-SOFC is the automatic evaluation and deterioration test system for single plate cell in SOFC. Unique sample setting mechanism enables highly reproducible measurement.
Gas composition, gas flow and temperature can be controlled by dedicated software. Combining with electrochemical instruments, impedance, OCP and I-V properties can be measured.
Standard cell (Ni-YSZ |YSZ |LSM dia.:approx. 
20mm) is prepared. It is useful to investigate the various performances and to compare with customer's cell.
