Abstract
A catalyst composition comprising at least one precious metal, wherein the catalyst composition is capable of catalyzing, in the presence of a halogen ion or a mixture of halogen ions, a charging reaction and a discharging reaction in a regenerative fuel cell. This disclosure relates to electrodes comprising those catalysts that are useful in fuel cells. The catalysts are active towards hydrogen evolution reaction (HER) and hydrogen oxidation reaction (HOR) and porous electrodes are made in a process designed to control their porosity. The catalysts and electrodes are employed in regenerative fuel cells comprising hydrogen and halogen acid or mixture of halogen acids. The catalysts are particularly useful in hydrogen/bromine reduction/oxidation reactions. The catalysts exhibit highly acceptable life and performance.
