HYDROPHOBIC CATALYST LAYER FOR FUEL CELL WITH SOLID POLYMER ELECTROLYTE, METHOD OF ITS PREPARATION, FUEL CELL WITH SOLID POLYMER ELECTROLYTE AND METHOD OF ITS PREPARATION

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to hydrophobic catalyst layer designed for fuel cell with polymer electrolyte and method of its preparation, as well as to fuel cell with polymer electrolyte and method of its preparation. According to the invention, catalyst layer designed for fuel cell with polymer electrolyte is formed from: catalyst derived by reducing platinum oxide; hydrophobic agent; proton conducting electrolyte, and hydrophobic agent mainly consists of alkylsiloxane. Compound Si containing hydrophobic substituent is contacted with platinum oxide. Compound Si is exposed to hydrolysis and polymerisation by catalyst effect of platinum oxide. Thereafter, this platinum oxide is reduced, whereby hydrophobic catalyst layer containing alkylsiloxane polymer is derived.;EFFECT: increase of catalyst application coefficient, low cost, stable characteristics of fuel cell with polymer electrolyte.;7 cl, 11 dwg, 1 tbl, 11 ex
