Proton exchange membrane fuel cells (PEMFCs) have attracted significant interest as a potential green energy source.However, if the performance of such systems is to be enhanced, appropriate control strategies must be applied.Accordingly, the present study proposes a sophisticated control system for a 1.0 kW PEMFC system comprising a fuel cell stack, an auxiliary power supply, a Tank DC-DC buck converter, and a DC-AC inverter.

The control system is implemented using an 8051 single-chip microcontroller and is designed to optimize the system performance and safety in both the startup phase and the long-term operation phase.The major features of the proposed control system are described and the circuit diagrams required for its implementation introduced.In addition, the touch-sensitive, intuitive human-machine interface is introduced and typical screens are presented.Finally, the electrical characteristics of the PEMFC system are briefly examined.

Overall, the results confirm that the single-chip microcontroller click here presented in this study has significant potential for commercialization in the near future.
