Abstract
In a multicell electric storage battery designed for central gas release, before being released into the open air the battery gases pass through a container positioned on the block casing in which the acid particles and moisture are separated from the gases as a consequence of the gases being repeatedly deflected by a series of walls placed in the path of the gases, which may be perforated if desired, and the dehumidified gases are then passed through a porous flame-protection frit. Flashback of a flame caused by external ignition of the gases is prevented by rapid burn-off of the gases in a flame extinguishing chamber preceding the frit.
