Supercharging Fuel Cells with Caffeine
2024.03.14
Fuel cells, while promising, are expensive due to high catalyst requirements to increase the oxygen reduction reaction (ORR) activity. In a breakthrough, researchers found that adding caffeine to the electrodes can improve the ORR activity of platinum electrodes 11 times. This discovery can enhance the efficiency of the fuel cell, reduce the requirement for excess platinum catalysts, and ultimately lead to cheaper and more efficient fuel cells.
