- Abstract
- Silicon fabrication technologies such as a photolithography, a wet chemical etching and an anodic bonding were introduced to form microchannel
on silicon wafer. Pt–Al2O3 (5 wt%, Johnson Matthey) was loaded into the micro-channel to perform methanol oxidation reaction that
is highly exothermic. The methanol oxidation reaction occurring in the micro-channel was investigated, and the heat of reaction and conversion
were evaluated under various pretreatment experimental conditions. The methanol oxidation reaction occurring over layer type catalyst in the
micro-channel showed the conversion over 90%, fast start-up and accurate temperature control.
After testing the performance of a miniaturized methanol catalytic burner (MCB) separately, it was applied to a reformer as a heat source,
and the performance of the reformer was analyzed. The temperature of a reformer-MCB stack consisting of three reformers and two MCBs was
successfully controlled only with the MCB without the support of the electric heater. The stack produced 73% hydrogen and 5000 ppm CO with
the methanol conversion of 65%.
