Direct Conversion of Coal Derived Carbon in Fuel Cells

  • John F. Cooper


A long-held dream of early energy science and technology has been a fuel cell that would directly convert coal char (if not raw coal) into electric power—bypassing the emission problems of combustion and the efficiency limitations of thermal cycles. Such a fuel cell would generate electric power from an electrochemical reaction similar to the combustion reaction of carbon:
$$ C + O_2 = CO_2 (\Delta H^0 _{298 K} = - 94.05 kcal/mole, E^0 = 1.02 {\text{V at }}750^\circ {\text{C}}) $$
As an example, the fuel cell (Fig. 1) might use carbon plates or particulates wetted with a molten alkali carbonate electrolyte, a melt saturated porous ceramic separator, and an air electrode catalyzed by lithiated NiO, such as used in the molten carbonate hydrogen fuel cell (Cherepy et al, 2005; Vutetakis, 1985; Weaver et al, 1979).
