It contains the PeakForce Tunnelling Atomic Force Microscopy (PF-TUNA, Bruker, USA) experiments on pristine and operated membrane electrode assembly (MEA) cathodes and the respective polystyrene - low density polyethylene (PS-LDPE) calibration files. All PF-TUNA files were generated with a Dimension Icon and the Nanoscope software (Bruker, USA). Additionally, nanoindentation data is stored herein with respective optical microscope images of the indented area. The nanoindentation data were generated with a Hysitron TI 980 and the TriboScan software (Bruker, USA) on the same MEAs as the AFM data.<br>
The data provides information about local MEA cathode aging upon long-term operation in a proton membrane electrolyzer cell with respect to porous transport layer related compression.
