For the most effective system (2 type B membranes), the unwanted transport rates were 4 x 10(-4) Mol h(-1) M-2 for Cu and 17 x 10-4 mol h(-1) m(-1) for Fe. The corresponding cell voltage was 0.774 V. The difference in the transport rates for Fe and Cu may be explained by the ion transport mechanisms in the studied systems.
