PS-Dual Range consists of a PC controlled, electronic load bank and a dual flow rate gas distribution unit that has 4 independent gas channels; 2 fuel and 2 for oxidants, with independent control of each line. Includes back pressure regulators, and gauges and humidifiers, operating on ElectroChem's proprietary Windows™-based software system. The user can program the cell temperature, humidification of the reactant gases and the load to the fuel cell. The fuel cell electrochemical performance along with the operating conditions is logged by Power Station™ and shown on the control screen. Test data is saved to a file that can be exported to a spreadsheet program for data sorting and printing of test results.

Fuel Cell Testing For Wide Dynamic Range

Beat the Resolution Limit Of Mass Flow Control!
Four Independent Gas Lines
Paired for Wider Range

Mass Flow Controllers (MFC) have a 1 part in 100 accuracy. To provide a high accuracy over a wide dynamic range (particularly in low flow ranges) the MFCs can be paired to provide a high and low flow range with much better precision.

When coupled with the Power Station, the PS-DR gas management unit enables fuel cell and electrochemical testing of wide ranging reactant gas mixtures for PEM, alkaline, and phosphoric acid fuel cells. It provides capacity for small single cells and to fuel cell stacks.

Key Features

• Software control supports enhanced gas flow control by “teaming” large and small mass flow controller “pairs”
• Precision automated gas supply, product water collection and effluent management.
• Convenient front panel access to manual controls, and output and return gas fittings.
• Safety designed in through hardware features and software control.
