The Grove cell was an early electric primary cell named after its inventor, British chemist William Robert Grove, and consisted of a zinc anode in concentrated sulfuric acid and a platinum cathode in concentrated nitric acid, the two separated by a porous ceramic pot.
The Grove cell was the favored power source of the early American telegraph system in the period 1840 - 1860 because it offered a high current output and higher voltage than the earlier Daniell cell (at 1.9 volts and 1.1 volts, respectively).
However, by the time of the American Civil War, as telegraph traffic increased, the Grove cell's tendency to discharge poisonous nitric acid gas proved increasingly hazardous to health, and as telegraphs became more complex, the need for constant voltage became critical. The Grove cell was limited in this respect, because as the cell discharged, voltage reduced. Eventually, Grove cells were replaced in use by Daniell cells.
