The method of a disk electrode (stationary and rotating) was used to study the regularities of changes in the mass transport properties of composite electrodes containing platinum nanoparticles on carbon black, the addition of carbon material with various forms of structural elements (three-dimensional and pseudo-one-dimensional carbon nanotubes with different length-to-diameter ratios), and the proton-exchange polymer Nafion. The transport of molecular oxygen inside a porous electrode to the platinum surface is investigated. Mechanisms for changing the mass transport properties of structurally modified electrodes in the course of electrochemical action are proposed.
