A micro-fuel processor system integrating steam reformer and partial oxidation reactor was manufactured using low temperature co-fired ceramic (LTCC). A CuO / ZnO / Al 2 O 3 catalyst and Pt-based catalyst prepared by wet impregnation were used for steam reforming and partial oxidation, respectively. The performance of the LTCC micro-fuel processor was measured at various operating conditions such as the effect of the ratio of the feed flow rate, the ratio of H 2 O / CH 3 OH and the operating temperature on the LTCC reformer and the CO clean-up system. The hydrogen concentration and the methanol conversion were high and stable as a durable micro-fuel processor from the feasibility test which was operated continuously for 12 h. The product gas was composed of 75% hydrogen, 25% carbon dioxide and carbon monoxide ( < 50 ppm ) at 260 ∘ C , respectively.
