Scribner 855 SOFC Test System
The Scribner 855: All-in-One Solid Oxide Fuel Cell Test System
The 855 SOFC Test system functions as a comprehensive, ready-to-use Solid Oxide Fuel Cell Test System. Equipped with a zero volt capability for lower measurement ranges, this unit offers enhanced capabilities with the integration of a programmable Power Supply, enabling electrolysis mode. Automated, hands-free switching between SOFC and SOEC mode is facilitated through FuelCell® software. Renowned for its high performance and accuracy, the 855 SOFC system comes with the FuelCell® Software and Experimental Methods Manual included, with optional Impedance Spectroscopy & HFR available.
