| Abstract: | The working mode of proton exchange membrane fuel cells (PEMFC) was introduced, and the digital DC/DC converter and DC/AC inverter were particularly described, which could improve the feeble output characteristics and the low output voltage of fuel cells. The control system circuit based on AT 89S51controller was designed, which could change the fuel cells to a stable, controllable and multifunctional digital power supply. |
