Carbon-based fuel cells

The direct carbon fuel cell (DCFC) is a power generation device converting the chemical energy of carbon directly into electricity. The energy is converted via direct electrochemical oxidation of the fuel and without any combustion or gasification processes. Compared to other technologies the solid carbon fuelled fuel cells have several unique features and advantages offering higher thermodynamic efficiency and lower emission of carbon dioxide per unit of the generated electricity. Furthermore, the fuel for the DCFC does not require any sophisticated preparation since the solid carbon can be easily obtained from various resources such as coal, petroleum coke, biomass (e.g. grass, woods, nut shells, corn husks), or even organic garbage.

Direct carbon fuel cell with molten hydroxide electrolyte (developed in Department of Energy Engineering) is considered as to be the most promising type of DCFCs, due to its advantages, such as high ionic conductivity, higher electrochemical activity of carbon (higher anodic oxidation rate and lower overpotentials) and higher efficiency of carbon oxidation due to the lower operating temperature (the dominant product of carbon oxidation is CO2 vs. CO). Accordingly, the DCFC may be operated at lower temperatures (roughly 673-873 K) and thus cheaper materials may be used to manufacture the cell.
