Fuel Cells - Exploratory Fuel Cells | Direct Carbon Fuel Cells

Direct carbon fuel cells (DCFCs) have attracted the attention of the researchers because of the increasing demand for clean and efficient techniques that use carbonaceous fuel sources. Direct carbon fuel cells are the only fuel cell technology that uses carbon as the fuel, which nevertheless provides several distinguishable advantages: (1) high energy density and efficiency, (2) low carbon dioxide emissions, (3) zero poisonous gas emissions (e.g., no NO_x and/or SO_x), and (4) abundant fuel resources (e.g., graphite, coal, biomass, and organic garbage). Research on DCFCs is discussed and summarized in this article. This article demonstrates that DCFCs are theoretically a feasible power generation technology and have the potential to be used in stationary and mobile applications. However, significant research is required to fill the gaps between experimental scale setup and commercial applications.
