The invention provides a fuel cell waste heat utilization system and method.The fuel cell waste heat utilization system comprises a liquid storage tank, a working medium pump, a fuel cell heat exchanger, a power generation module and a condenser which are connected in series through a pipeline to form a circulation loop, organic working media are stored in the liquid storage tank, and the fuel cell heat exchanger can absorb waste heat generated by a fuel cell assembly; the organic working medium is vaporized to drive the power generation module to generate power, and the vaporized organic working medium can be cooled and liquefied by the condenser. By the adoption of the structure, when the fuel cell assembly is in the working state, the working medium pump is started, the organic working medium in the liquid storage tank circularly flows in the pipeline, the organic working medium absorbs waste heat generated by the fuel cell assembly through the fuel cell heat exchanger, is converted into a vapor state and enters the power generation module, and then the power generation module is driven to generate power; the purpose of utilizing the waste heat of the fuel cell is achieved, and then the condenser outside the vehicle can cool the organic working medium into a liquid state, so that the organic working medium continues to circulate in the loop.

    本发明提供一种燃料电池余热利用系统及方法,包括储液罐、工质泵、燃料电池换热器、发电模块和冷凝器,上述部件通过管道串联形成循环回路,所述储液罐内储有有机工质,所述燃料电池换热器能够吸收燃料电池组件产生的余热,使所述有机工质汽化驱动所述发电模块发电,所述冷凝器能够将汽化的所述有机工质冷却液化。采用如上结构,在燃料电池组件处于工作状态时,开启工质泵,使储液罐内的有机工质在管道内循环流动,有机工质通过燃料电池换热器吸收燃料电池组件产生的余热,化为汽态进入发电模块后,驱动发电模块即可发电,达到了对燃料电池余热进行利用的目的,之后车外冷凝器即可将有机工质冷却为液态,使有机工质继续于回路内循环。
