The 850e is ideal for single-cell and short-stack fuel cell research and university programs, and the powerful FuelCell software package is included for controlling station operation.

The model 850e Multi-Range Fuel Cell Test System is a complete test station for operation and measurement of PEM/DMFC fuel cells. The 850e combines a computer-controlled instrument (multiple current-range programmable electronic load, fuel and temperature controls, and data acquisition functions) with fuel handling hardware in an integrated bench-top unit. The 850e uses the proven 890e as the basis for the electronic load design. The 850e may be used with a single-cell or small stack, a host computer, and reactant and purge gas supplies.

• Multiple current range electronic load choices: 5/25/50A or 10/50/100A
• Suitable for up to 50 cm² PEM cells.
• Computer controlled operation using FuelCell software with GPIB interface.
• Temperature controlled anode and cathode humidifiers.
• Computer control of anode and cathode mass flow rates.
• Automatic control of N₂ purge gas to cell.
• Detection of pressure loss for reactant and purge gasses.
• High performance 316L stainless steel humidifiers, and heated gas transfer lines.
• Constant current, voltage or power control modes.
• Continuous cell resistance measurement.
• Automatic hardware shutdown for over-current, under-voltage, over-power, load temperature, and cell temperature alarm conditions.
• High impedance whole-cell and reference electrode sense inputs.
• Cell main terminals and sense inputs tolerant of a non-isolated cell.
