A sensor and a sensing method for use in a gas or gaseous mixture is provided. The sensor includes a gas sensitive material, MO,, in which M is predominantly or exclusively MO and MO,, is a substoichiometric molybdenum trioxide which exhibits a response in the form of an increase or a decrease in an electrical property of the material in the presence of a gas. The gas sensitive material is in communication with two or more electrodes and is arranged for being contacted with a gas or gaseous mixture. The electrodes are in direct communication with the gas sensitive material by being in contact therewith. The sensor incorporates a temperature sensor. The sensor includes a heating element.

There is disclosed a lead acid battery and battery separator, the separator comprising a porous ceramic body manufactured from ceramic fibers welded together at their respective contact points such that the resulting separator body is substantially rigid and non-compressible and wherein the separator has a porosity of at least about 90%. The electrodes of the battery may be comprised of a similar porous ceramic material impregnated, respectively, with Pb and PbO.sub.2. A lead-containing foil may be maintained in close contact with each of the electrodes as current collectors attached to the battery terminals.
