As hydrogen energy is being promoted increasingly, the relationship between hydrogen diffusion and crystal structure in metal materials developed for hydrogen-permeable membranes, such as vanadium, should be clarified for the purpose of membrane design. In this study, we analyzed fusion images of surface hydrogen distribution maps obtained from hydrogen permeability tests and crystal orientation distribution maps obtained from the raw data analysis of electron backscatter diffraction (EBSD). We used multivariate analysis, such as principal component analysis (PCA) and multivariate curve resolution (MCR). Consequently, the image fusion and multimodal data analysis revealed factors correlated with each measurement method, demonstrating the ability to extract essential information that could not be obtained from a simple comparison of hydrogen permeability and crystal orientation.
