  • FUEL CELL SYSTEM ARCHITECTURE FOR ARTIFICIAL INTELLIGENCE DATA CENTERS
    Publication number: 20260074522
    Abstract: The present disclosure is directed to a system that employs fuel cell-based power generation for various loads, such as data centers for artificial intelligence (AI) model training. The system utilizes various modules, such as different types of energy storage devices, to supplement power output by the fuel cells, as well as store any excess power generated by the fuel cell systems. As a result, swings in the power output by the fuel cells are minimized and the life of the fuel cells may be extended.

  • Microgrid including dual mode microgrid inverter and load management method
    Patent number: 11990790
    Abstract: A microgrid includes a power system configured to output system power and an automatic transfer switch (ATS). The ATS includes a normal terminal that is electrically connected to a grid power line configured to receive grid power from a power utility, an emergency terminal that is electrically connected to a system power line configured to receive system power from the power system, and a load terminal that is electrically connected to a critical load line configured to provide power to a critical load. The microgrid also includes a bypass line electrically connected to the system power line and the critical load line, so as to bypass the ATS, and a circuit breaker configured to control power flow through the bypass line.
