A fully integrated micro-channel fuel processor system consisting of vaporizer, steam reformer, heat exchanger and preferential CO oxidation (PROX) was developed using low temperature co-fired ceramic (LTCC). To fabricate a compact all-in-one system, each substrate was stacked to build a multilayered type fuel processor. A CuO/ZnO/Al2O3 catalyst and Pt-based catalyst prepared by wet impregnation were deposited inside the micro-channel of steam reformer and PROX, respectively. The performance of the fully integrated micro-channel reformer wasmeasured at various conditions such as the ratio of the feed flow rate, the ratio of H2O/CH3OH and the operating temperature of the reactor. In parallel with the experiments, 3-D fluid dynamics simulation (Fluent) was conducted to verify the micro-reformer performance. The fully integrated micro-channel reformer has the dimensions of W: 130 mm × D:50 mm× H: 3 mm. The fuel processor produced the gas composition of 71% H2 and 25% CO2, and more than 93% of methanol conversion was achieved at 300 ℃ and 2 cm3/h of the feed flow rate when CO concentration was maintained below 100 ppm by PROX.
