HYDRA-M Solid-State Metal Hydride Fuel Cell Systems

HYDRA-M is a solid-state metal hydride fuel cell system designed for safe, silent, and long-duration portable power in demanding environments. By storing hydrogen in a solid metal hydride material and supplying it to a PEM fuel cell stack, HYDRA-M delivers reliable 60W–120W power for man-portable, tactical, military, and UAV applications. The system provides portable hydrogen power + military applications without conventional high-pressure hydrogen cylinders, making it suitable for field electronics, remote sensors, communications equipment, and other applications where low-signature, long-duration power is required.

Metal Hydride Fuel Cell Technology & Solid-State Hydrogen Storage

HYDRA-M uses solid-state hydrogen storage based on metal hydride materials, allowing hydrogen to be stored in a stable solid form at near-ambient pressure. This metal hydride fuel cell architecture combines solid-state hydrogen storage with a PEM fuel cell stack to provide portable, long-duration power without conventional high-pressure hydrogen cylinders.

How a Metal Hydride Fuel Cell Works

HYDRA-M combines solid-state metal hydride hydrogen storage with a PEM fuel cell stack to generate electricity on demand. Hydrogen is stored within a solid metal hydride material and released when required by the fuel cell system. This metal hydride fuel cell architecture avoids conventional high-pressure hydrogen cylinders and provides portable hydrogen power for man-portable, tactical, military, and UAV applications.

Solid-State Metal Hydride Fuel Cell vs. Lithium, Compressed Hydrogen & Diesel

vs. Lithium Batteries

Up to 3× higher specific energy per kilogram. Zero self-discharge over months of storage. No thermal runaway risk —Eliminates the thermal runaway mechanism associated with lithium-ion batteries.

vs. Compressed Hydrogen (70MPa)

HYDRA-M does not require conventional Type IV high-pressure hydrogen tanks. Hydrogen is stored within a solid metal hydride material, reducing the need for high-pressure storage and associated handling infrastructure.

vs. Diesel Generators

Silent operation ≤45dB with no combustion exhaust and low acoustic and thermal signatures, making HYDRA-M suitable for field and tactical applications where operational signature matters.

HYDRA-M for Tactical & Military Portable Power

HYDRA-M provides portable hydrogen power architecture for military portable power where reliable, long-duration electricity is required without conventional high-pressure hydrogen storage. Its low acoustic signature, solid-state hydrogen storage, and portable 60W–120W power range make the system suitable for man-portable power, field electronics, communications equipment, remote sensors, battery charging, and other tactical power requirements.

For missions where low acoustic output, long runtime and portable hydrogen storage are important, HYDRA-M provides a solid-state approach to tactical hydrogen power.

For applications requiring a man-portable fuel cell or a fuel cell for military field operations, HYDRA-M provides a solid-state hydrogen alternative to conventional battery and combustion-based power systems.
