A Direct Carbon Fuel Cell (DCFC) is a fuel cell that uses a carbon rich material as a fuel such as bio-mass or coal. The cell produces energy by combining carbon and oxygen, which releases carbon dioxide as a by-product. It also called coal fuel cells (CFCs), carbon-air fuel cells (CAFCs), direct carbon/coal fuel cells (DCFCs), and DC-SOFC.
Direct carbon fuel cell with molten anode
This invention discloses a method of converting carbon-containing materials directly to electrical energy without the need for intermediate processing steps. An embodiment comprises the use of a conductive molten medium with dispersed particles of carbon material as the anode in a fuel cell with a solid oxide electrolyte which enables conversion of carbon-containing materials (such as pulverized coal, charcoal, peat, coke, char, petroleum coke, oil sand, tar sand, waste plastics, biomass, and carbon produced by pyrolysis of carbonaceous substance) directly into electrical energy in a single step process. The anode optionally may have a dispersed second solid phase that getters CO2 and SO2 gases that are produced during the anodic reaction. Hence, this invention facilitates near-zero emissions and dramatically reduces the release of environmentally harmful emissions. More importantly, this direct route to electrical energy eliminates Carnot cycle constraints and offers high thermodynamic efficiency.
