Each microstructured stainless steel foil was brazed in vacuum for stacking. Inner surface of micro channels was coated with Al2 O3 layer to support Pt catalyst by sol-gel method. The stack was designed like a cross-flow type heat exchanger to perform the combination of exothermic and endothermic reactions simultaneously. It is expected to apply to the micro reformer which produces hydrogen for micro PEMFC (Proton Exchange Membrane Fuel Cell). As the first step in our study, we measured experimentally the heat transfer rate and the spatial temperature distribution of the stack. An then, the reaction of C3 H8 -air with heat transfer to cold air flow was performed in the stack. As a consequence, quantitative and qualitative thermal characteristics of the stack for reaction were investigated.
