Figure 4.109 Schematic picture of dialytic battery.

Inserting the numerical values given in section 3.7.2, and T=300 K, the cell electromotive force becomes ϕ≈0.05 V. The actual value of the external potential, Δϕext, may be reduced as a result of various losses, as described in section 4.5.1 (e.g., Fig. 4.105). ϕ is also altered if the “fresh” water has a finite amount of ions or if ions other than Na+ and Cl are present.

If the load resistance is Rext, the power delivered by the cell is given by the current Iϕext Rext−1,

E=IΔϕext,
