Abstract
A unitized regenerative fuel cell (URFC) employs a molten salt electrolyte for negative ion transfer by operating at temperatures above that of aqueous reactants for supporting gas-phase reactants, and the molten salt mitigates the need for reactant based catalysts by serving the dual role of the electrolyte as well as an optional catalyst or catalyst solvent. The molten-salt electrolyte (MSE) hydrogen-halogen unitized regenerative fuel cell is adaptable for microgrid electricity storage applications. Configurations herein employ a molten-salt electrolyte and a closed system of the reactants for cycling between charge and discharge modes. The URFC employs reactants including hydrogen and halogen as the oxidant, which is more reactive and energy efficient than oxygen employed in conventional URFCs, and avoids platinum electrodes by employing a high temperature, gas-phase, system which further reduces reactant crossover issues.
