A new type of hybrid battery/fuel cell employing liquid lithium provides operation in three modes. (1) In a fuel cell mode it will take in gaseous fuel and air to produce electricity. (2) In the battery mode a higher electrical output can be sustained during the time that the reaction converting liquid lithium to bulk lithium hydride can be maintained. (3) In the electrolysis mode the device employs electric power and steam to produce hydrogen and oxygen.
•Liquid Li reduces electrode poisoning problems caused by components of fuel gas. •Increased power due to increased reaction sites across the anode. •Estimated performance at 0.5 V at peak power and .5 W/cm2 – 1 W/cm2.
