1283138 Accumulators ACCUMULATOR ENWERK HOPPECKE CARL ZOELLNER & SOHN KG 11 Aug 1970 [21 Feb 1970] 38637/70 Heading B1F [Also in Division H1] A device for the catalytic recombination of oxygen and hydrogen gases evolved by an accumulator comprises a casing 1 of metal, plastic, or ceramic material having an opening 2 for connection to the accumulator housing, the casing receiving a platinum metal catalyst 6 within a gas-permeable container 4. The container 4 has its opening 3 to the atmosphere sealed by a gas-permeable plug 5 having a high resistance to gas flow so that a limited excess pressure may exist within the accumulator. Preferably, the container 4 and plug 5 are of ceramic material but, alternatively, porous glass or plastics may be used. The parts 4, 5 may be rendered hydrophobic with the aid of silicone resin. The water formed by the reaction returns to the accumulator via the opening 2. In a modification the casing 1 is omitted and the opening 3 is sealed in an aperture in the wall of the accumulator casing. |
