A scientific article co-authored by Asif Guliyev, Associate Professor and Dean of the Faculty of Engineering at Baku Engineering University (BEU), and Vurgun Gahramanov, Associate Professor and Deputy Dean, has been published in open-access format in the Scopus-indexed, Q1-category "International Journal of Hydrogen Energy."

In the study, titled "Multiscale Modeling of Coupled Hydrogen Diffusion and Degradation in Porous Powder Materials Accounting for Trap Saturation Kinetics," a nonlinear multiscale computational model was developed for hydrogen diffusion and damage in sintered porous materials used in PEM electrolyzers. The results show that the saturation of microstructural traps causes hydrogen transport to shift to the damage front. This reduces the efficiency of the electrolyzer stack by 25–40% and shortens its service life by approximately 50%. Optimal design of the microstructure could theoretically lower the levelized cost of hydrogen (LCOH) by 22–37%.

The results of the study are of practical significance in the fields of hydrogen energy, materials science, and powder metallurgy. The article can be accessed through the following links:
