- Аннотация: Two sets of electrocatalysts for ethanol electrooxidation were synthesized: PtSnX (X = Ni, Co, Mn, V) and RuM (M = Cr, Ti, Mn, V, W). It was shown by transmission electron microscopy (ТЕМ) and cyclic voltammetry (CV) that particle size of PtSnX metallic phase is equal to 2-2,5 nm and its specific surface area is 80-90 m2/g, which is close to structural performance of the commercial catalyst. Electrocatalytic activity of studied samples was determined from polarization curves obtained in 0,5 M H2SО4 and H3PО4 solutions containing 1 M C2H5OH. PtSnNi and PtRu catalysts were tested in ethanol-oxygen fuel cell layout (FC). The maximum power density achieved was 65 mW/cm2 in the case of FC with PBI membrane and 95 mW/cm2 for FC with Nafion membrane.
