Methanol steam reforming can convert methanol solution into hydrogen rich steam, which can be used to supply for the proton exchange membrane fuel cell (PEMFC). The carbon monoxide (CO) in the produced hydrogen rich steam will be poison to the PEMFC and limits the application of this technic. This study develops a new methanol fuel processing system (MFPS) with incorporated methanol steam reforming and CO selective methanation modules for production of hydrogen rich steam with a low concentration of CO, and used to directly supply for the PEMFC. The core component of the MFPS is a highly layer‐packed microreactor, wherein methanol steam reforming, methanol combustion, and CO selective methanation reactions can occur. For the developed MFPS, an optimized methanol supply strategy is proposed to startup the MFPS, the fastest startup time is about 15.8 minutes. Experimental tests showed that the MFPS can be continuously operated for more than 100 hours with CO concentration below 10 ppm. The produced hydrogen rich steam was directly supplied for a PEMFC to generate 100 W electricity. Results obtained in this study demonstrated that the developed MFPS can produce CO‐free hydrogen rich stream for the supply of PEMFC, the generated electricity can be used to power mobile device and/or electronics.

具有甲醇蒸汽重整和CO选择性甲烷化模块的甲醇燃料处理系统，用于PEMFC

甲醇蒸汽重整可将甲醇溶液转化为富氢蒸汽，可用于为质子交换膜燃料电池（PEMFC）供应。产生的富氢蒸汽中的一氧化碳（CO）对PEMFC有害，并限制了该技术的应用。这项研究开发了一种新的甲醇燃料处理系统（MFPS），该系统结合了甲醇蒸汽重整和CO选择性甲烷化模块，可生产低浓度CO的富氢蒸汽，并直接用于PEMFC。MFPS的核心组件是高度填充的微反应器，其中可以发生甲醇蒸汽重整，甲醇燃烧和CO选择性甲烷化反应。对于已开发的MFPS，提出了优化的甲醇供应策略来启动MFPS，最快的启动时间约为15。8分钟 实验测试表明，MFPS可以在CO浓度低于10 ppm的情况下连续运行100多个小时。产生的富氢蒸汽直接提供给PEMFC，以产生100 W的电能。这项研究获得的结果表明，开发的MFPS可以产生富含CO的不含氢的料流，用于PEMFC的供应，所产生的电能可用于为移动设备和/或电子设备供电。
