Gas recovery device for storage batteries
Abstract
Abstract Gas recovering devices for storage batteries comprise a catalyst body disposed in a housing defining a gas recovering chamber which is isolated from the gas space within the storage battery by a sintered, porous, explosion preventing structure disposed between the body of catalyst and an opening from the housing disposed for intercommunicating the latter and the interior of the battery. The sintered, porous, explosion preventing structure includes a water-repellent portion and a water-permeable portion. The water-permeable portion is disposed beneath the catalyst body for returning water produced in the catalyst to the interior of the battery through the opening. The water-repellent portion is disposed to facilitate the passage of gases developed int he battery during the charging of the latter into contact with the catalyst body.
