Abstract :
This paper discusses aspects of gas recombination by precious metal catalysts and their role in valve-regulated lead-acid (VRLA) batteries. It describes a test method to determine catalyst efficiency, that is the percentage of hydrogen and oxygen that is recombined to form water. Testing is not only an important quality control tool but is also necessary to verify the integrity of the catalyst in its surroundings and to determine its limitations in varying operating environments.
