Title: Influence of the degree of platinum dispersion on the electrochemical properties of the three-phase boundary in water electrolysis with a solid polymer electrolyte

Abstract

Hydrogen production via water electrolysis with a solid polymer electrolyte occurs at the electrocatalyst/solid electrolyte/water three-phase boundary with the resulting condition that the structure of this interface greatly influences the energy efficiency of the process. Structure optimization not only improves the efficiency of the process but also achieves savings in noble metal consumption. The goal of this paper is to study the properties of this boundary as functions of the degree of electrocatalyst dispersion, the amount of electrocatalyst used, and the technology used to apply the electrocatalyst. Platinum was obtained by the sodium borohydride reduction of chloroplatinic acid. An iridium dispersion, for comparative purposes, was obtained by the same procedure from chloroiridic acid. The electrolyte consisted of a polyvinyl alcohol membrane. Photomicrography and scanning and transmission electron microscopy were used for structure analysis.
