Comprehensive Study of the Stability of PtCu/C Catalysts for Low-Temperature Fuel Cells
The catalytic activity in the oxygen-reduction reaction and stability in various stress-testing modes are studied for bimetallic PtCu/C catalysts with platinum contents of 20 and 30 wt %, obtained by liquid-phase synthesis methods, is studied by cyclic-voltammetry methods on a rotating disk electrode in a three-electrode cell and as part of a membrane-electrode assembly in comparison with a commercial Pt/C catalyst. Significant differences in the degree of degradation of the studied PtCu/C and Pt/C catalysts for low-temperature fuel cells are shown, namely from 33 to 67% depending on the stress-testing method and catalyst composition.
