    • Mesh refers to the number of openings per linear inch of a screen. The mesh size of a particle is the mesh screen having the largest openings on which the particle is retained. The mesh size of the American Sieve Series is related to the size of the opening, in cm as: (size in cm) = 2/(mesh size) for mesh sizes above 50, and (size in cm) = (1.5)/(mesh size) for mesh sizes below 40. In kinetic equations, we used the size of the opening in cm as the characteristic size of a particle of coal l because the linear size is not defined for a particle of an arbitrary shape.

    • We cannot compare the sustained current and power output of our cell with similar values reported for high-temperature CFCs. The literature on high-temperature CFCs does not specify the fraction of electrons available from the complete oxidation of fuel in the cell that was consumed while the "sustained" performance of the cell was characterized.

    • The fraction of oxidizable functional groups that are on the surface of a particle of coal is inversely proportional to the radius of the particle when the groups are distributed homogeneously throughout the particle.
