the sheet resistance of porous electrodes is essential for improving the performance of polymer electrolyte membrane (PEM) water electrolyzers and related technologies. Despite its importance, existing methods often fail to provide reliable and comprehensive data, especially for porous materials with complex morphologies and non-uniform thicknesses. This study introduces a robust and straightforward method for determining the sheet resistance of porous electrodes using a novel probe concept based on industrial printed circuit board (PCB) technology. This probe measures resistance across ten distances, ranging from 250 µm to 2500 µm, enabling local mapping of resistance. The study focuses on the sheet resistance of key components in PEM water electrolyzers, including the gas diffusion layer (GDL), porous transport layer (PTL), and catalyst layers deposited on a membrane. Additionally, an image-processing-based method is presented to obtain the thickness distribution of the studied catalyst layers, facilitating a detailed analysis of the electrical in-plane resistivity with thickness variations. Overall, this methodology has the potential to expedite material integration and bridge the gap between electrode engineering and single-cell testing, thereby advancing the development of PEM water electrolyzers.\r\n\r\nThis dataset provides the Gerber fabrication files for the custom PCB-based probe introduced in the associated publication. The files contain the PCB layer and geomertry data needed to reproduce the probe geometry with its ten measurement distances from 250 µm to 2500 µm; the measurement procedure and data evaluation are described in the related article."},"dsDescriptionDate":{"typeName":"dsDescriptionDate","multiple":false,"typeClass":"primitive","value":"2025-01-24"}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Chemistry","Engineering","Physics"]},{"typeName":"keyword","multiple":true,"typeClass":"compound","value":[{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"catalyst layers"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"image processing"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"in-plane electrical resistivities"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"polymer electrolyte membrane (PEM) water electrolyzers"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"porous electrodes"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"printed circuit boards (PCBs)"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"sheet resistances"}}]},{"typeName":"publication","multiple":true,"typeClass":"compound","value":[{"publicationCitation":{"typeName":"publicationCitation","multiple":false,"typeClass":"primitive","value":"N.
