| Abstract Scope |
In hydrogen research, hydrogen is typically electrochemically charged into metals to simulate hydrogen intake in industrial applications. In this study, we explored the reverse process: electrochemically extracting hydrogen from metals in various forms, ranging from solid solutions to metal hydrides. The results demonstrated that this approach can effectively extract hydrogen and mitigate hydrogen embrittlement, thereby restoring the mechanical properties of the metals. Various electrolytes were tested to enhance the feasibility of this method for industrial applications. Furthermore, the extracted hydrogen could be stored with high efficiency. This concept not only provides a solution for preventing hydrogen embrittlement but also opens new possibilities for utilizing the extracted hydrogen and even hydrogen stored in hydrogen-storage alloys. |
