Fuel Cell Operating on Neat Formic Acid

Pure, or nearly pure, (neat) formic acid is easily oxidized electrochemically. It also has sufficient energy density to produce a system with over 600 Wh/kg net energy density. We propose to combine Lynntech's light, simple, and rugged monopolar fuel cell technology with high activity catalysts produced using technology developed by Vanderbilt University to produce a high energy density fuel cell system. This system will use a high activity catalyst with a lower precious metal content than current formic acid electrooxidation catalysts to minimize active area of a fuel cell stack for use in a system where pure fuel is supplied to the anode and only CO2 vented. The catalyst is utilized in a fuel cell system that has a minimum of moving parts and support structure to produce the complete power supply. This combination will lead to a lightweight, rugged, reliable power supply suitable for use with either one time use disposable cartridges or bulk fuel.
