Fuel oxidizing catalyst, method for preparing the same, reformer including the same, and fuel cell system including the same

A method of preparing a fuel oxidizing catalyst for a fuel cell, the method comprising:

• dissolving a Ce precursor and an M precursor in a Cu-containing solution;
• and
• heating the precursor dissolved solution,
• wherein M is a transition metal.

A reformer for a fuel cell comprising:

• a heating source for generating heat through an oxidizing catalyst reaction of a fuel and an oxidant;
• and
• a reforming reaction part for generating a hydrogen-rich gas through a reforming catalyst reaction,
• wherein the fuel oxidizing catalyst comprises:
• a metal oxide comprising CeO2, MO, and CuO, and
• wherein M is a transition metal.

A fuel cell system comprising:

• a reformer comprising:
• a heating source for generating heat through an oxidizing catalyst reaction of a fuel and an oxidant, and
• a reforming reaction part for generating a hydrogen-rich gas through a reforming catalyst reaction,
• wherein the fuel oxidizing catalyst comprises:
• a metal oxide comprising CeO2, MO, and CuO, and
• wherein M is a transition metal;
• at least one electricity generating element for generating electrical energy through an electrochemical reaction of hydrogen gas and an oxidant;
• a fuel supplier for supplying the fuel to the reformer and the electricity generating element;
• and
• an oxidant supplier for supplying the oxidant to the reformer and the electricity generating element.
