Abstract
A fuel cell reforming catalyst includes a platinum-group metal; an inorganic oxide selected from CeO2, Pr6O11, and combinations thereof; a strong acid ion; and a carrier. The fuel cell reforming catalyst has high activity for the reforming reaction at low temperatures and low space velocities.
Claims26
A reforming catalyst for a fuel cell comprising:
- a platinum-group metal;
- an inorganic oxide selected from the group consisting of CeO2, Pr6O11, and combinations thereof;
- at least one strong acid ion;
- and
- a carrier.
2 more elements
A method of preparing a reforming catalyst for a fuel cell, the method comprising:
- mixing an inorganic oxide precursor and a carrier in a first solvent to prepare a first catalyst precursor, wherein the first catalyst precursor includes an inorganic oxide supported on the carrier;
- impregnating the first catalyst precursor in a strong acid solution to prepare a second catalyst precursor, wherein the second catalyst precursor includes an inorganic oxide surface-treated by the strong acid;
- mixing the second catalyst precursor and a platinum-group metal-containing precursor in a second solvent to prepare a mixture;
- and
- firing the mixture.
