Abstract
Devices and methods for generating electricity in a direct carbon fuel cell are provided herein. The method includes heating and melting an alloy to obtain a liquid alloy anode; circulating the liquid alloy anode through a porous ceramic cathode, the cathode being a tubular structure and in communication with oxygen; reducing the oxygen at the porous cathode to obtain oxygen ions for diffusing through an electrolyte to the liquid alloy anode; and oxidizing the oxygen ions at the liquid alloy anode thereby generating electricity. The direct carbon fuel cells have high electronic conductivity, high carbon solubility with fast carbon diffusion, lower viscosity and eutectic temperatures, and rapid fuel dissolution kinetics.
