[Objectives]A portable solid oxide fuel cell(SOFC)system includes a gas supply module,a fuel processing module,an SOFC power generation module,a thermal management module,an exhaust treatment module and a control module.There is a complex coupling relationship between the fuel processing module and the SOFC power generation module.Clarifying the coupling characteristics between them is crucial for improving system performance and operating time.[Methods]The effects of temperature,the carbon-to-oxygen ratio and other factors on the performance of catalytic partial oxidation(CPOx)of propane with Rh as catalyst were analyzed,and the coupling performance of CPOx and SOFC stack was further tested.[Results]With the increasing of fuel flow rate,the reforming efficiency first increases and then decreases.The most suitable flow rate is 100 or 150 mL/min.An increase in temperature can continuously improve the reforming efficiency,but the improvement in reforming efficiency at high temperatures caused by an increase in temperature gradually decreases.The optimal C/O ratio obtained from the experiment is 1.0.Under the optimal operating conditions,the output power of SOFC stack reaches 8.38 W.[Conclusions]Under the conditions of propane flow rate of 150 min-1,carbon and oxygen mole fraction ratio of 1.0,and operating temperature of 800℃,the coupling performance between SOFC stack and CPOx is the best,the portable propane power generation system can generate 150 W of power with a volume of 12 L.
