Replication Data for: Proton Exchange Membrane Water Electrolyzer Cathode: A Nanomechanical and Nanoelectrical Analysishttps://doi.org/10.26165/JUELICH-DATA/XF24KTBorowec, JulianPoc, Jean-PierreBasak, ShibabrataDobrenizki, LadislausSchmid, GünterJodat, EvaKarl, AndréEichel, Rüdiger-A.Hausen, FlorianJülich DATA2025-05-232025-12-02T11:50:15ZThis replication data set provides the raw data for the publication: "Proton Exchange Membrane Water Electrolyzer Cathode: A Nanomechanical and Nanoelectrical Analysis" (DOI: 10.1149/1945-7111/add213) 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. 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.
