Structure of platinum–carbon electrodes containing various forms of nafion proton-conducting polymer

Scanning electron microscopy, atomic force microscopy, and cyclic voltammetry have been used to perform a complex comparative study of the structure of hydrogen fuel cell electrodes consisting of nanostructured platinum on carbon black and electrodes containing a proton-conducting Nafion polymer introduced into the electrode in the form of a solution and in a precoagulated state. It has been shown that, in the latter case, the specific area of electrochemically active platinum increases significantly (by up to two times).
