Daniell, John Frederick

Figure 14.5 shows the basic arrangement of a electrochemical cell called the Daniell cell. This cell is named for John Frederick Daniell (1790-1845) who constructed this type of cell in 1836. The Daniell cell components include zinc and copper solutions in separate containers. Between the solutions is a salt bridge... 

A battery cell that became popular during the nineteenth century was constructed in 1836 by the English chemist John Frederick Daniell.This cell used zinc and copper. The basic principle was that of Volta s battery pile, but each metal was surrounded by a solution of the metal ion, and the solutions were kept separate by a porous ceramic barrier. Each metal with its solution was a half-cell a zinc half-cell and a copper half-cell made up one voltaic cell.This construction became the standard form of such cells, which exploit the spontaneous chemical reaction...
