Abstract:

To address the challenge of insufficient endurance in energy systems under deep-sea conditions, this study designed, analyzed, and validated a hydrogen production system based on aluminum-water reactions, integrated with a fuel cell system to meet the demands of complex underwater environments. The reactor features a grid-like reinforced framework and lightweight, high-strength materials, which enhance structural rigidity and optimize dynamic water intake control and heat dissipation. Experimental tests, including cold start, hot start, pressure stability, and underwater integrated operation, were conducted on a simulated deep-sea closed environment platform. The results demonstrate that the system can stably supply hydrogen with minimal pressure fluctuations and exhibits excellent performance under different startup conditions. During extended underwater operations, the fuel cell output remained stable without noticeable degradation, and the variations in cabin temperature and humidity were minor, reflecting the system's effective thermal and humidity balance and environmental adaptability. These findings confirm the engineering feasibility and practical value of aluminum-water hydrogen production technology. This system provides robust energy supply support for complex deep-sea environments and offers valuable insights for optimizing energy systems in deep-sea equipment design.
