Fundamental Study of a Novel Compact Hydrogen Generation System Fueled by Sodium Borohydride and Boric Acid

In recent years, hydrogen has emerged as a promising next-generation energy source, offering a sustainable alternative to fossil fuels. Compact and user-friendly hydrogen generation systems are also required to realize a hydrogen-based society. This paper introduces a novel hydrogen generation system employing sodium borohydride and boric acid as fuel sources. The approach introduced successfully reduces the challenges related to reaction bubbles and water input that hindered efficient hydrogen generation. Furthermore, experimental analysis confirms the effectiveness of the hydrogen reactor and emphasizes its practical significance.
