Cogeneration System Based on Methane Reforming for Hydrogen Production and Proton Exchange Membrane Fuel Cell

提出了一种甲烷重整制氢与质子交换膜燃料电池相结合的热电联产系统,并对集成系统流程进行了模拟。在该系统中,氢气由甲烷水蒸气重整制得,燃料电池利用制得的氢气对外供电。同时,余热回收系统充分利用系统中各个环节的余热,以满足生活热水和供暖需求。结果表明,该集成系统能够正常运行,并同时输出电能和热能,在无氢地区应用具有可行性。

A cogeneration system combining methane reforming to produce hydrogen and proton exchange membrane fuel cells is proposed, and the integrated system flow is simulated. In this system, hydrogen is produced by reforming methane and steam, and the fuel cell uses the produced hydrogen to supply electricity. At the same time, the waste heat recovery system makes full use of the waste heat in all aspects of the system to meet domestic hot water and heating needs. The results show that the integrated system can operate normally and simultaneously output electric and thermal energy, which is feasible for application in hydrogen-free areas.
