Direct liquid fuel cells are considered an ideal electrochemical energy device to supplement Li-batteries in some special applications, due to the higher energy density of liquid fuel, quiet operation, and independent of charging plugs. We are interested in develop direct carbohydrazide fuel cells with high power density and high energy and fuel efficiency. Now we are investigating electrochemical reaction mechanisms of carbohydrazide, hydrazine and ammonia over different types of catalysts in various conditions, and exploring efficient anode catalyst materials, with the ultimate goal of developing novel carbohydrazide fuel cell technologies.
