A 0.8 KW Programmable Electronic power Load for Fuel Cell Dynamic Test System

In order to investigate the output characteristic of a fuel cell based on the electrical empirical model, A 40A/0.8KW/100V, high performance dynamic Fuel Cell load system with total protection circuits is presented using with parallel power MOSFETs ,Analog and digital Isolation technique. This efficient dynamic load utilizes current and voltage Feedback to realize protections. The safety is increased due to employing both control commands and feedback signals. This programmable dynamic load will be very useful to optimize the Fuel cell design, improve the operation performance, and develop the real-time control system of fuel cells. A good match is found between simulation results and experimental data. The electronic load remotely programmed via an RS-232 serial port.
