摘要: A new procedure for the preparation of SPE-electrocatalyst composites has been developed. In this procedure, noble metal cationic species are chemically reduced within a solid polymer electrolyte. The metallic particles not homogeneously distributed across SPE thickness but predominate near its surfaces. structure and distribution precipitates, along membrane have investigated by scanning electron microprobe analysis transmission microscopy. Application to water electrolysis performed using Nafion membranes platinum-group electrocatalysts. prepared according present good electrochemical properties, low catalyst loadings, long-time stability high energetic efficiencies.
