LOW-TEMPERATURE WATER GAS SHIFT REACTION OVER Pt-Rc/TiO_2 CATALYST FOR PEMFC

摘要

The Pt/TiO_2 with rutile structure showed superior catalytic activity for LT-WGS. The addition of Re to Pt/TiO_2 (rut.) catalyst brought about a remarkable increase in the catalytic activity. The catalytic activity of Pt-Re/TiO_2 (rut.) catalyst exceeded that of the commercial Cu/Zn catalyst at 250℃. From the above results, it is expected that the Pt-Re/TiO_2 (rut.) catalyst is a candidate for catalyst that replaces the commercial Cu-Zn catalyst.
