摘要
介绍了质子交换膜燃料电池(PEMFC)的工作方式,并针对其输出特性偏软、电压偏低的特点,详细介绍利用数字化DC/DC变换器和DC/AC逆变器改善燃料电池输出特性,提高输出电压的方法。设计了基于AT89S51控制器的控制系统硬件电路平台,将燃料电池转换成稳定可控并可提供多电平-交/直电流的多用途数字电源。
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.
