Oxygen Absorbing Metal-Air-Batteries for Long Term Cargo Compartment Inertisation

One of the main challenges for Halon free fire suppression in cargo compartments is the long term inertisation for the ETOPS duration after the initial knock down phase. Known concepts like bottled nitrogen and OBIGGS systems are relatively heavy and have several reliability and safety issues. A novel and very innovative approach for inertisation is binding the oxygen in metal oxides instead of bringing nitrogen into the compartment. Metal-air-batteries are promising candidates for this principle as they allow for a controlled metal-air reaction. In this topic the metal – electrolyte combination shall be selected, a battery integration concept shall be created. A demonstrator shall be built and tested. Finally the demonstrator will be integrated the topic leader Fire Test Facility for long term fire suppression tests. Please refer to the full topic descriptions document published in this call.
