Grove cell: Difference between revisions

The '''Grove cell''' was an early electric [[primary cell]] named after its inventor, [[United KingdomWales|BritishWelsh]] chemistphysical scientist [[William Robert Grove]], and consisted of a [[zinc]] [[anode]] in dilute [[sulfuric acid]] and a [[platinum]] [[cathode]] in concentrated [[nitric acid]], the two separated by a porous ceramic pot.

The Grove cell was the favouredfavored 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).

By the time of the [[American Civil War]], as telegraph traffic increased, the Grove cell's tendency to discharge poisonous [[nitrogen dioxide]] (NO₂) fumes 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 cellscell]]s.
