Direct Carbohydrazide Fuel Cell 

Research 5.jpg
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. We have reported metal-free catalysts for direct carbohydrazide fuel cell, and have recently demonstrated a direct carbohydrazide fuel cell with very high output power density of over 900 mW./cm2.
