METHOD FOR FUEL CELL CATALYST PREPARATION

摘要

FIELD: chemistry. ^ SUBSTANCE: method for fuel cell catalyst preparation includes preparation of chloroplatinic acid solution or preparation of the mixture of chloroplatinic acid with metal salts in water-organic solvent containing nonaqueous component in amount up to 95%, its mixing with carbon powder, ultrasonic dispergation of the obtained mixture and chemical reducing of platinum compound and other alloy component. ^ EFFECT: implementation of the process in absence of the reagents enabling the negative affect to performance stability of catalysts based on platinum alloys and possibility to obtain the catalysts with prescribed values of structure characteristics. ^ 16 cl, 1 tbl, 17 ex, 6 dwg
