7. BUSINESS SENSITIVE CHOSS / SOFC Description  CHOSS – Combined Hydrogen Oxygen Storage System  Standard industrial strength hydrogen peroxide and metal hydride supply system provide separate streams of hydrogen and oxygen for electric power generation via Solid Oxide Fuel Cell and shaft power via waste heat recovery.  High energy dense, air-independent power system  Underwater power generation applications  Space based power applications  SOFC – Solid Oxide Fuel Cell  Electrochemical conversion of hydrogen oxidation to electric power.  Solid oxide electrolyte requires high temperature operation which enables very high cycle efficiencies via waste heat recovery. 7 High storage density supply of H2 and O2 enables efficient power generation without access to atmospheric air.
