- Scribner extends its groundbreaking line of tabletop fuel cell testing equipment with the 885 Fuel Cell Potentiostat.
- The 885 bolts directly to Scribner’s 850 Multi-Range Fuel Cell Test Systems or 890 / 890C / 890ZV Fuel Cell Test Loads (different form-factors), offering an easy, efficient testing platform while delivering real results with Scribner Associates’ fuel cell test systems.
- Integrated potentiostat for 840 /850 / 855, Series Fuel Cell Test Systems / 890 Series Fuel Cell Test Loads
- 3 current ranges for maximum flexibility and current accuracy (20 mA, 200 mA, 2 A)
- ZView® included for EIS data analysis
- Sweep function for CV and LSV measurements
- Automated switching between load and potentiostat operation
- Combine with the 850 Auto Multigas Unit for automated switching between normal fuel cell operation and diagnostic mode (CV/LSV
- Perform automated experiments within FuelCell®
- No need to swap cell leads to use potentiostat functions
- Voltammetry for in-situ fuel crossover & electrochemical surface area measurement
- Potentiostatic mode for electrode and catalyst support durability test
- Fine current resolution for high accuracy Tafel experiments
- Quick & easy Installation
- Data analysis with FCView®and CViewTM
- Optional FRA for EIS measurements (1mHz to 40 kHz)
