Abstract
Abstract PRIOR APPLIANCES FOR THE CATALYTIC RECONSTITUTION INTO WATER OF THE HYDROGEN AND OXGEN GENERATED BY ELECTRIC ACCUMULATORS SUFFER FROM THE DISADVANTAGE THAT AN APPRECIABLE AMOUNT OF THE GASES OR WATER VAPOUR ESCAPE TO THE ATMOSPHERE. THE INVENTION PROVIDES A GAS PROOF CASING LINKED WITH THE INSIDE OF THE ACCUMULATOR AND CONTAINING A CATALYST CONTAINER INSERTED INTO THE CASING THROUGH AN OPENING WHICH IS SUBSEQUENTLY SEALED BY A POROUS ELEMENT OF HIGH FLOW RESISTANCE. THE CASING MAY COMPRISE THE CASING OF THE ACCUMULATOR GAS CHAMBER.
