Magnesium-solution phase catholyte semi-fuel cell for undersea vehicles

摘要: Abstract A magnesium-solution phase catholyte semi-fuel cell (SFC) is under development at the Naval Undersea Warfare Center (NUWC) as an energetic electrochemical system for low rate, long endurance undersea vehicle applications. This consists of a magnesium anode, sodium chloride anolyte, conductive membrane, catalyzed carbon current collector, and chloride, sulfuric acid hydrogen peroxide. Bipolar electrode fabrication to minimize stack volume, duration testing, scale-up electrodes from 77 1000 cm 2 have been objectives this project. Single multi-cell testing 77 cm configuration utilized optimize all parameters including start-up conditions, flow rates, temperatures, electrolyte concentrations while maintaining high voltages efficiencies. The bipolar operating parameter optimization large area cells will be presented. Designs electrodes, patterns current/voltage distribution across these also discussed.
