| 摘要 |
The present invention relates to a composition for enhancing the utilization of catalysts in fuel cell, comprising catalysts, proton-exchanged ionic polymers, and coupling agents. The coupling agents are bonded to the catalysts or catalyst carriers by a B1 functional group and bonded to the proton-exchanged ionic polymers by a B2 functional group. The present invention also relates to a method for enhancing the utilization of catalysts in fuel cell, comprising the steps of (a) utrasonicating catalysts; (b) adding coupling agents to bond to the catalysts; (c) adding a perfluoro polymer to form a catalyst-coupling agent-perfluoro polymer complex whereby developing stable dispersion; wherein the coupling agents in step (b) are bonded to the catalysts by a B1 functional group and bonded to a perfluoro polymer by a B2 functional group. The present invention also provides a complex for enhancing the utilization of catalysts in fuel cell, comprising catalysts, coupling agents, and proton-exchanged ionic polymers, wherein the coupling agents are bonded to the catalysts by a B1 functional group and bonded to the perfluoro polymer by a B2 functional group to form a complex.
