Abstract
A reaction catalyst for the recombination of the oxyhydrogen gas produced by lead-acid storage batteries into water in a controlled, exothermic reaction, where the catalyst element is a solid rod element with a central heat conducting core, the catalyst rod being positioned inside a gas-tight housing in communication with the battery gas space. This rod element is produced by a fabricating method in which granular catalyst carrier material is worked into a paste which is then shaped and dried, the metallic catalyst being deposited on the surface of the carrier grains.
Claims8
A unitary catalyst element for catalytically recombining into water a gas mixture of oxygen and hydrogen formed during operation of a lead-acid storage battery, comprising a single elongated catalyst carrier body in the form of a permeable coherent solid;
- an active metallic catalyst material of the platinum group carried on the surface of the permeable catalyst carrier body;
- and an axially disposed core member of highly heat conductive material enclosed within said catalyst carrier body.
A method for fabricating a unitary catalyst element for catalytically reconverting into water a gas mixture of hydrogen and oxygen resulting from operation of a lead-acid storage batter, comprising the steps of:
- admixing water with a granular catalyst carrier material to form a paste;
- shaping said paste into a three-dimensional form of elongated configuration;
- drying the shaped carrier material;
- providing said elongated form with a longitudinally disposed central core of a highly heat conductive metallic material;
- and
- applying an active metallic catalyst material of the platinum group to the surface of said catalyst carrier material.
