The standard cell potential is given by $\begin{array}{rl}{\mathrm{E}}_{\text{cell }}^o& ={\mathrm{E}}_{\text{cathode }}^{\circ }-{\mathrm{E}}_{\text{anode }}^o\\ {\mathrm{E}}_{\text{cell }}^{\circ }& ={\mathrm{E}}_{\mathrm{Cu}}^{\circ }-{\mathrm{E}}_{\mathrm{Ni}}^{\circ }\\ & =(0.337\mathrm{V})-(-0.257\mathrm{V})\\ & =0.337\mathrm{V}+0.257\mathrm{V}\\ & =0.594\mathrm{V}\end{array}$
