Abstract
A direct carbon fuel electrochemical device and method for generating electricity. The apparatus includes a solid oxide electrolyte having an anode side and a cathode side. Carbon and at least one metal oxide are provided to the anode side for reaction at the anode and air is provided to the cathode side. At least a portion of the carbon is oxidized and at least a portion of the metal oxide is reduced to a metal or lower oxide metal oxide on the anode side. The metal or lower oxide metal oxide is electrochemically reoxidized with oxygen in the air, thereby generating electricity.
