Why primary cell have 1.5 V only?

It depends on the electron configuration. Different metals have single electrode potential. They are both +ve and -ve. We use standard Hydrogen electrode whose potential is taken to be 0. Using that we can find half potential. Then right from that we get the total potential of a cell. So it is all natures work
