The positive electrode for an air/zinc element is a depolarizer mass attached to a perforated plastic carrier with interposition of a conductive foil and a metal foil take-off conductor, both also perforated. The perforations in the plastic carrier are in the form of hollow rivets extending toward the foils, the foils are engaged by their own perforations concentrically upon said rivets, and the rivets have outwardly protruding collars extending over the foils, whereby the foils are attached and all perforations are aligned. |
