摘要：

Disperse catalytic compositions for water electrolysis in electrolyzers with a solid polymer electrolyte were obtained by magnetron sputtering of C-Pt and Mo-Ir sectional targets. The catalysts were studied by X-ray diffraction analysis, electron microscopy, and voltammetry. The synthesized Pt-. and Ir- Mo catalysts with lowered contents of the precious component were subjected to prolonged trials in an electrolysis cell with a solid polymer electrolyte and showed high activity and stability.
