A fuel cell test system that is powered by proton exchange membrane fuel cells (PEMFCs) has been developed. It consists of two parts: hardware units and software programs. The hardware units contain a PEMFC stack, water-cooling components, air-cooling, hydrogen humidifying and filtering, temperature and pressure monitoring, and voltage and current measuring of the stack. The software programs, developed according to the features of the PEMFC stack, are used to control the whole process. The software programs are composed of the control interface of the PEMFC test system and controllers, such as the basic measurements and control tools, proportionalintegral-derivative (PID) controller, fuzzy logic controller, and other advanced controllers. The system can supply 500 W of DC 20 V /30 A power continuously by using hydrogen. This paper describes a high-efficiency development method, and PID and fuzzy-PI controller design, which are suitable for various applications in experiment and study of PEMFC engineering. The test system has a good human-machine interface. It is easy to operate and control all kinds of parameters and variables, and clearly shows the charts and graphs. By using this test system, a lot of research projects can be conducted in the field of PEMFC in the future. © Institution of Engineers, Australia 2007.
