摘　　要：With a broad range of application prospects,hydrogen fuel cell technology is regarded as a clean and efficient energy conversion technology.Nevertheless,challenges exist in terms of the safe storage and transportation of hydrogen.One proposed solution to this problem is the utilization of methanol on-line steam reforming technology for hydrogen production.In this paper,an integrated system for in-situ steam reforming of fuel coupled with proton exchange membrane fuel cells(PEMFC)power generation is proposed,and sensitivity analysis and exergy sensitivity analysis are conducted.Through the gradual utilization of waste heat and the integration of the system,fuel consumption is reduced and the power generation efficiency of the system is improved.Under the design operating conditions,the power generation efficiency and exergy efficiency of the system are achieved at 44.59%and 39.70%,respectively.This study presents a proven method for the efficient integration of fuel thermochemical conversion for hydrogen production with fuel cells for power generation,highlighting the advantages of complementary utilization of methanol steam reforming and PEMFC.
