INTRODUCTION Today in China, the use of fossil fuels in vehicles has caused several environmental problems, such as emission of particulate matters (PM), NOx, SOx and so on. As an ideal energy carrier, hydrogen has advantages of high energy density, high conversion efficiency and being harmless to the environment. Thus, hydrogen-based fuel cell becomes a good choice of power source for vehicles. Traditionally, hydrogen is produced from electrolysis of water, which consumes much electricity, and produces a mixture of oxygen and hydrogen which needs to be separated through expensive and complicated technologies. Consequently, it is desirable to find better ways to produce hydrogen. Hydrogen production from methanol reforming has the advantage of generating high-concentration hydrogen with low energy consumption. However there are challenges in design reactor for methanol reforming, such as uneven distribution of temperature in the reactor, low efficiency of heat exchange and large reactor size. Therefore, it is necessary to design an improved reactor to address these challenges.
