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.
Evaluation and deterioration test for single cell. Full automatic system by dedicated
software. Support software reduces the possibility of error in operation.
Sample Single flat plate(dia.:approx. 20mm) *Other diameters are negotiable Gases
