ABSTRACT:
A catalytic system for CO removal includes a gold (Au) catalyst and a co-catalyst in contact with an aqueous phase, and a fuel cell system using the same. The catalytic system is relatively very simple compared to a common CO removal system, and can highly efficiently remove CO at low temperature without side reaction. In addition, water contacted in the catalytic system can act as a buffer for the rise and fall of temperature, and thus, can cope with an accidental temperature change. Further, the catalytic system shows a low operation temperature, and thus, can be operated over a broad operation range considering the activity and/or selectivity of the gold catalyst, etc.
