A method of manufacturing a fluid permeable electrical resistance heater element having a structure that promotes uniformity of flow of fluid through the element and a uniformity of heating throughout the element. The method comprises forming a fluid permeable body of unbonded carbonizable fibres. A latent solvent is applied to the fibres and the solvent is subsequently caused to dissolve at least a surface of the fibres so as to effect bonding of the fibres together. The carbonizable fibres are subsequently carbonized to produce a fluid permeable carbon body.

A cathode current collector for a sodium sulphur cell is formed of a metal substrate, for example of a nickel alloy such as Inconel 600, which is provided with a firmly adherent coating of carbon which is produced by decomposition of a carbon-containing gas in a glow discharge with the substrate heated to a temperature of 200.degree. C. to 1000.degree. C. in an electric field, conveniently a radio frequency field employed for inductively heating the substrate.
