微反应器中甲醇自热重整

Automotive exhaust is currently one of the major pollution sources. As a pollution-free and energy-saving power supply for electric vehicles, the fuel cell is the best candidate because of its high energy conversion efficiency (50%～70%) and zero or nearly zero emission. Hydrogen is the fuel for the proton exchange membrane fuel cell (PEMFC). The on-board generation of hydrogen using liquid alcohols and hydrocarbons is the most practical way for PEMFC vehicles. Nowadays, PEMFC technology has been well developed, and is gradually in the stage of commercial application, while the hydrogen-generating technology has become the bottle-neck for the practical utilization of fuel cells. The miniaturization of the hydrogen source is prerequisite for its practical application.[1,2].
