Abstract

The invention relates to a miniaturized hydrogen production integrated device through methanol autothermal reforming and a hydrogen production method. The hydrogen source technology is characterized by integrating main reaction units such as the methanol autothermal reforming and CO selective oxidation (PROX), and only using two stages of the CO selective oxidation without the prior CO water-gas conversion unit; and the hydrogen source integrated system comprises a group of methanol autothermal reforming/heat exchange modules, a group of catalytic combustion/vapourization modules, and two groups of CO selective oxidation/heat exchange modules, wherein the four groups of modules all adopt a welding integration method of an integral catalytic reactor and a microchannel heat exchanger. The device and the method can obtain 1 kW class reformed gas (dry gas) of which CO concentration is less than 30 ppm and H2 concentration is more than 53 percent. The invention is particularly suitable for fuel cell hydrogen source systems in the range of between 100W and 100kW.
