摘要:

质子交换膜燃料电池(PEMFC)是一种将氢气燃料的化学能转化为电能的装置,具有高能效、低排放、低噪声等优点。空气源热泵(ASHP)是一种通过用少量电驱动,将热能从低品位转换为高品位的装置,可根据季节的不同为建筑提供制冷和供暖并满足生活用水需求。基于PEMFC-ASHP的冷热电联供系统以PEMFC的电堆和ASHP作为双能量驱动单元,通过热泵技术进一步利用PEMFC发电过程中产生的余热,为建筑用户提供电力、热源和冷源,实现冷热电联供系统的能源高效利用。研究结果表明,ASHP能够提升PEMFC的工作性能,冷热电联供系统能效达150%,ASHP的性能系数为2~4,PEMFC的净发电效率约为40%,PEMFC-ASHP的整体㶲效率达44.46%。

Abstract:

The proton exchange membrane fuel cell (PEMFC) is an electrochemical energy conversion device that converts the chemical energy of hydrogen fuel into electrical energy, characterized by advantages such as high energy efficiency, low emissions, and low noise. The air-source heat pump (ASHP) is a device driven by a small amount of electricity to upgrade thermal energy from low-grade to high-grade, capable of providing cooling and heating for buildings according to different seasons and meeting domestic hot water demand. The combined cooling, heating, and power system based on PEMFC-ASHP employed the fuel cell stack and ASHP as dual energy-driven units. Through heat pump technology, the waste heat generated during the power generation process of the fuel cell was further utilized to simultaneously provide electricity, heating, and cooling for building occupants, thereby achieving high-efficiency energy utilization in the combined cooling, heating, and power system. The results showed that the ASHP could enhance the operational performance of the PEMFC system. The system's energy efficiency reached 150%, the coefficient of performance of the ASHP subsystem ranged between 2 and 4, the net power generation efficiency of the PEMFC was approximately 40%, and the overall exergy efficiency of the PEMFC-ASHP integrated system reached 44.46%.
