Abstract
A comparative analysis of the microstructure and electrochemical behavior of platinum–carbon electrocatalysts containing 20 and 40% platinum from different manufacturers for fuel cells with a proton-exchange membrane is carried out. The degree of degradation of the catalysts during accelerated stress testing in laboratory conditions is assessed based on the results of not only residual functional characteristics, but also microstructural parameters after electrochemical tests. It is determined that 20 and 40% PM series catalysts contain smaller platinum nanoparticles, characterized by a narrower size and more uniform spatial distribution, compared to analogues of the HiSPEC series. Due to these microstructural features, a PM-series platinum–carbon catalysts are characterized by a higher electrochemically active surface area (EASA) and mass activity values initially and after stress testing.
