Addition of carbon black as a conductive support to bimetallic catalysts for use in anion exchange membrane fuel cells
The anion exchange membrane (AEM) fuel cell has the potential to become an important energy conversion technology. Unlike proton exchange membrane (PEM) fuel cells, AEMs do not use noble metal catalysts, allowing them to potentially become low-cost alternatives to PEMs. The purpose of this research is twofold: To increase the methanol oxidation current produced by the bimetallic catalyst used by AEM fuel cells; To reduce the catalyst ability to split water. To accomplish this, carbon black was added during various steps in catalyst processing.
