WebE_cell = E_standard_cell_potential - (RT)/ (nF) * ln ( [products]/ [reactants]) So it depends on the sign of the log term. If concentrations of the products are greater than the concentrations of the reactants, then the cell potential will become more negative as temperature increases. (the log bit keeps the second term negative).
