| Abstract Scope |
This talk will present performance enhancements in a liquid metal anode Direct Carbon Fuel Cell (DCFC) using a new cathode-supported electrolyte tube. The tube consists of a porous perovskite electronic conductor as current collector and support, with a porous cathode, and dense solid electrolyte outside. The liquid metal anode is an iron-tin base alloy with high carbon solubility and low liquidus temperature to facilitate very fast mass transfer. This makes the cell a cross between a solid oxide fuel cell and basic oxygen furnace steelmaking vessel. This DCFC class could potentially be used for biomass energy with carbon capture for negative-emissions electricity generation at high efficiency and with a simpler flow sheet than gasification designs. The talk will focus on the relationship between processing parameters for the cathode-electrolyte system, its structure, and its effect on performance of the overall cell. |
