The Bunsen cell is a zinc-carbon
electric cell (colloquially called "battery") composed of a
zinc
electrode in dilute
sulphuric acid separated by a porous
diaphragm from a carbon (graphite)
electrode in
nitric or
chromic acid.
The cell is named after its inventor, German chemist
Robert Wilhelm Bunsen, who improved upon the
Grove cell by replacing
Grove's
platinum electrode with a much cheaper
gas retort carbon. This battery, like Grove's, emitted
noxious fumes.
Bunsen used this cell to extract metals from their salts by
electrolysis, enabling him to isolate metallic magnesium for
the first time.
