abstract

PtRuIr/C catalyst was prepared via a microwave-irradiated polyol plus annealing (MIPA) synthesis strategy. Tests by CO stripping voltammetry and in the single PEM fuel cells showed a greatly high CO-tolerant performance of the catalyst. The catalyst was characterized by a series of techniques, such as TEM, XRD, EDS, XPS and gas chromatography, etc., and the data were discussed with respect to the PtRu/C catalyst prepared following the same procedure. On the basis of the characterizations, the performance-structure relationship was explored and a speculative mechanism was supposed.
