An accurate solution to equation 1 was supposed to be a three-dimensional solution with tolerance made to the flow of current in the stretched parallel dimension of the cell, portrayed as x-direction in Fig 2 below. As a matter of fact, current in this direction is minimal when compared to parallel current moving in the short dimension of the cell displayed as direction y and to even greater currents moving in the perpendicular direction, displayed in figure 2 as the z-direction. As a result, computer time can be saved significantly by using only two dimensions that are y and z to solve the equation. In addition to that, more time can be salvaged by making use of the cell’s symmetry, which is assuming y is a constant implying that there is no current flowing across that surface. The other periphery conditions considered in this computation include the assumption that electric potential E has a zero value at the end of the collector bar, while again the value of E is equated to the voltage drops for electrochemical deducted from the whole-cell voltage drop.
