HyPAT: A GUI for high-throughput gas-driven hydrogen permeation data analysis

Abstract

The Hydrogen Permeation Analysis Tool (HyPAT) is a Python-based graphical user interface (GUI) that streamlines data analysis for hydrogen gas-driven permeation experiments to measure the following hydrogen transport properties in materials: permeability, diffusivity, and solubility. HyPAT rapidly analyzes batches of experimental data, produces required analysis plots, and creates an organized report of analyzed data. A built-in literature database provides direct comparison of experimental results to the hydrogen transport properties of 27 different materials. The database also allows permeation rate and time-scale estimates for experiment preparation based on user-defined input parameters. HyPAT is designed to be easily customized to researchers’ needs, allowing for adaptations such as adding materials to the literature database and accounting for differing experimental output files and setups. A verification and validation study shows accurate analysis of deuterium permeation experimental data with a pure nickel sample.
