Power Station™ Control Software
Power Station™ Control Software
Power Station™ is operated by using our proprietary Windows™-based software. The fuel cell system is controlled by specifying the number of cells to test, cell sizes, operating conditions, and type of performance tests. A graphical user interface allows the operator to quickly scan the operating state of all fuel cells together or individually for detailed performance. Polarization performance is displayed in different graphical representations as well as written to data files for posttest analysis. Multi-sequence electrochemical tests may be programmed to simulate electrical load conditions ranging from constant voltage, current, or power to cyclic studies and dynamic loads.
