Hydrogen Production by a Methanol Steam Micro-Reformer for Fuel Cell Applications

A novel design of plate-type microchannel reactor has been developed for fuel cell-grade hydrogen production. Commercial Cu/Zn/Al2O3 was used as the catalyst for the reformingreaction, and its behavior was evaluated by examining the mole fraction of products, methanol conversion, hydrogen yield as well as the amount of carbon monoxide under various operatingconditions. Subsequently, 0.5 wt% Ru/Al2O3 as methanation catalyst has been prepared byimpregnation method and coupled with MSR step to evaluate the capability of methanol processor for reducing of CO. Based on the experimental results, the optimum conditions were obtained infeed flow rate of 5 mL/h and temperature of 250 °C leading to a low CO selectivity and high H2 yield. The constructed fuel processor had a good performance and excellent capability for onboard hydrogen production
