ABSTRACT:
A direct carbon fuel cell having an anode electrode of carbon particles pre-wetted with carbonate, a cathode electrode, and an electrolyte layer disposed between the anode electrode and the cathode electrode and containing a molten carbonate. The fuel cell includes a wicking feature whereby excess carbonate produced during the operation of the fuel cell is removed. The use of carbonate pre-wetted carbon particles as the anode provides a network of empty voids, facilitating the removal of CO2gas from the cell, thereby enhancing fuel cell performance.
