Development of Gasoline Fuel Reformer for Fuel Cell Powered Vehicles : Ceria-based Water Gas Shift Catalysts |
| 초록 |
On-board fuel processor is the most convenient method of supplying hydrogen in the absence of a suitable infrastructure for hydrogen. The WGS reaction is one of the key catalytic stages in a fuel processor. Existing commercial Cu-Zn/Al2O3 (LTS) catalyst, though highly active, was unsuitable for fuel cell powered transportation applications. The WGS reaction over Pt- and (or) Ni-containing cerium oxide catalysts was investigated to develop a high performance WGS catalyst with high stability. The thermal cycling performance over the prepared catalysts was compared with that over the commercial Cu-Zn/Al2O3 catalyst. It was found that Pt-Ni/ceria catalysts displayed reasonably good activity than Cu-Zn/Al2O3 catalyst. It was also found that Ni-Pt/ceria catalysts showed higher stability than the commercial LTS catalyst during thermal cycling test. These results suggest that the Pt-Ni/Ceria catalysts are attractive candidates for development as the alternate commercial LTS catalyst for the fuel cell powered vehicles applications. |
