Abstract:
By means of the disk-electrode method (stationary and rotating), regularities of changes in the mass-transport properties of composite electrodes containing platinum nanoparticles on carbon black, the addition of carbon material with different shapes of structural elements (three- and pseudo-one-dimensional carbon nanotubes with different length-to-diameter ratios), and the Nafion proton-conducting polymer were studied. The transport of molecular oxygen inside a porous electrode to the platinum surface has been studied. Mechanisms for changing the mass-transport properties of structurally modified electrodes during electrochemical action are proposed.
Keywords:
ionomer, platinum, proton-exchange polymer Nafion, CNT.
