855 SOFC Test System
Product Descriptions
The 855 SOFC Test system is an integrated, turn-key Solid Oxide Fuel Cell Test System. This unit has a zero volt capability for lower measurement range. The addition of a programmable Power Supply extends the 855’s capabilities to include electrolysis mode. Automated, hands-free switching between SOFC and SOEC mode via FuelCell® software. The 855 SOFC system is known for it’s high performance and accuracy.
FuelCell® Software and Experimental Methods Manual are included. Optional Impedance Spectroscopy & HFR.
