Our project focuses on the design and simulation of a 1 megawatt hydrogen fuel cell power system for data center applications. As artificial intelligence and high-performance computing continue to expand, data centers require large amounts of clean, stable, and reliable power. However, rapid fluctuations in demand can strain traditional grid systems, leading to inefficiencies and potential instability. To address this challenge, our team is developing a system that uses a hydrogen fuel cell as the primary power source, supported by a hybrid energy storage system consisting of a battery and a supercapacitor. This combination allows the system to respond quickly to sudden changes in demand while maintaining steady and efficient operation. The system is designed to operate independently of the grid, improving resilience and reliability. It is also scalable, allowing multiple units to be combined into larger systems capable of supporting up to 10 megawatts of power. Using simulation, we evaluate system performance under realistic demand conditions, including rapid load changes. Our goal is to demonstrate how hydrogen fuel cell technology, combined with advanced energy storage and power electronics, can provide a clean, efficient, and reliable solution for next-generation data centers.
