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.

Abstract Proton exchange membrane fuel cell (PEMFC) is a crucial route for energy saving, emission reduction and the development of new energy vehicles because of its high power density, high energy density as well as the low operating temperature which corresponds to fast starting and power matching. However, the rare and expensive Pt resource greatly hinders the mass production of fuel cell, and the development of highly active and durable non-precious metal catalysts toward the oxygen reduction reaction (ORR) in the cathode is considered to be the ultimate solution. In this article, a highly active and durable Fe-N-C catalyst was facilely derived from metal organic framework materials (MOFs), and a favorable structure of carbon nanotubes (CNTs) were formed, which accounts for a desired good durability. The as-optimized catalyst has a half-wave potential of 0.84V for the ORR, which is comparable to that of commercial Pt/C. More attractively, it has good stabilities both in rotating disk electrode and single cell tests, which provides a large practical application potential in the replacement of Pt catalyst as the ORR electrocatalyst in fuel cells.
