159 § 52. The Bunsen Battery. — This battery, in- vented by Professor Bunsen, consists of a composite cell containing two elements in two distinct fltiids, separated from each other by a porous earthenware partition. The outer containing cell and the inner porous cell are similar in every respect to those employed in the Grove battery just described. The positive element and the solutions in both cells are also the same. It differs only from the Grove in having a plate or cylinder or bar of gra...phite, that is, of hard carbon similar to the scurf carbon obtained from gas retorts. In the older forms of the Bunsen cell, this carbon was moulded into the form of a cylinder, but, in the more modern forms, the carbon (negative) element is in the form of a square bar from I to 2 inches square, and of a length suitable to the height of the cell in which it is used. Round porous cells are employed to suit this form of carbon. Plates of carbon may be employed if square or rectangular porous cells are used.
