抜粋

For the further spread of PEFC technology, reduction of Pt-loading in PEFC has been targeted in order to reduce the cost. First, MEAs with various Pt-loading and carbon loading were made and evaluated using a standard 46.5%Pt/KB (TEC 10E50E). The correlation between Pt-loading and activation overvoltagc, and the correlation between carbon loading and concentration overvoltagc were investigated. Consequently, the minimum requirement of platinum was found to 0.15-0.20 mgPt/cm2, and the optimum carbon loading was found to 0.46 mgC/cm2 in our experimental conditions. Furthermore, the methods to increase CL thickness without increasing Pt-loading were considered, and then importance of homogeneous platinum dispersion in CL has been realized.
