Giner Labs Non-Flow-Through Fuel Cell (NFTFC) is a hydrogen/oxygen fuel-cell technology designed for air-independent power generation and high-density energy storage. The system dead-ends hydrogen and oxygen into the stack so that almost all supplied reactant can be consumed by the fuel-cell reaction, supporting high fuel utilization. Its non-flow-through architecture removes the need for gas humidification and flow-control equipment, simplifying the supporting balance of plant. Giner states that the NFTFC is suited to long-duration discharge and demanding energy-density applications and can be coupled with a suitable electrolyzer to form a closed-loop regenerative fuel-cell system.

Use Cases

  • Air-independent hydrogen power generation
  • High-density energy storage
  • Long-duration discharge missions
  • Aerospace and other environments where ambient air is unavailable
  • Regenerative fuel-cell energy-storage systems

Capabilities

  • Converts stored hydrogen and oxygen electrochemically into electrical power
  • Consumes nearly all supplied reactants through dead-ended gas operation
  • Simplifies balance-of-plant by eliminating humidification and gas-flow-control requirements
  • Supports closed-loop regenerative operation when paired with a suitable electrolyzer
