Investigation of bromine complexed hydrogen/bromine regenerative fuel cells for portable electric power
Abstract
A novel polyethylene glycol-bromine complexing system has been developed which significantly lowers the vapor pressure of bromine in a hydrogen/bromine fuel cell. The effect of temperature and acid concentration on complex formation have been studied. Heats of formation and rate constants for complex dissociation have been measured. A cathode has been optimized for use with bromine in a hydrogen/bromine fuel cell. Fuel cell performance utilizing the complex as a source of bromine was investigated.
