Cell potential has to be positive in order for the reaction to be spontaneous because in the equation deltaG = -nFEcell, in order for delta G to be spontaneous (negative), Ecell must be positive.
That is because in the equation ΔG = - nFE, a positive cell potential is associated with a negative Gibbs free energy, which means a reaction is spontaneous. A negative cell potential would make the Gibbs free energy positive, meaning that the reaction is no longer spontaneous.
