PEM 2D XRF Analysis Software for Catalyst-Coated Membrane Cross-Sections

In addition, the software provides a thickness-estimation workflow based on absorption-contrast images. The resulting thickness maps can be used for thickness-corrected quantification of elemental distributions within the membrane or catalyst-coated regions. The script was developed using PEM water electrolysis CCM cross-section datasets as reference; therefore, the default variables, plotting settings, segmentation parameters, and quantification workflow follow this example application.

However, these parameters can be modified and adapted to other compatible XRF map datasets. Input data should consist of processed XRF maps exported in a compatible TIFF format, where each image or stack channel represents an elemental emission signal or absorption-contrast signal. This repository represents the archived version associated with the corresponding scientific work.

The actively maintained version of the code is available in the linked GitHub repository. LINK: "github.com/Leonardolac97/PEM-XRF-evaluator/"
