SiC/graphitic carbon nanosheet (SiC/GC) nanocomposites, with 17 nm SiC NPs dispersed on GC uniformly were synthesized via a novel vaporization–deposition–reduction strategy derived from coconut shells and silica ceramic chips, which can be used as excellent supports for Pt toward the MOR.

First Time

In this paper we have successfully demonstrated a new micromachined fuel processing system including vaporizer, catalytic combustor and methanol steam reformer. This fuel processing system utilizes the thermal energy generated from the catalytic hydrogen combustion to heat up the entire system. For the first time, we have used carbon nanotubes as a supporting structure of Pt catalyst for combustion. The catalytic combustor could supply the energy to heat the reformer and maintain its working temperature. We have also developed a new coating method of reforming catalyst (Cu/ZnO/Al2O3) and observed that adequate amount of hydrogen can be generated for PEMFC. We have successfully reported the feasibility of the proposed fuel processing system in each assembled component.
