Cell invented in 1843 by the German chemist Robert Bunsen (1811 – 1899), consisting of a cylindrical glass vessel containing a zinc cylinder to which an electrode is attached, with a porous partition and a tilted carbon prism inside, at the top of which the positive electrode was fixed.

The glass jar contained a solution of sulphuric acid, separated by the porous septum from the nitric acid solution in which the carbon was immersed.

This type of battery has the drawback of producing noxious nitrous oxide gas.
