An electrocatalyst material having improved stability to corrosion compared to existing conductive high surface area carbon and metal carbide support materials is disclosed. The electrocatalyst material comprises (i) metal carbide nanotubes and (ii) a metal or metal alloy deposited on the metal carbide nanotubes. The electrocatalyst material is suitable for oxidising hydrogen, reducing oxygen or evolving hydrogen.

Electrocatalyst

An electrolyte membrane including (i) a porous mat of nanofibres, wherein the nanofibres are composed of a non-ionically conducting heterocyclic-based polymer, the heterocyclic-based polymer comprising basic functional groups and being soluble in organic solvent; and (ii) an ion-conducting polymer which is a partially- or fully-fluorinated sulphonic acid polymer. The porous mat is essentially fully impregnated with ion-conducting polymer, and the thickness of the porous mat in the electrolyte membrane is distributed across at least 80% of the thickness of the electrolyte membrane. Such a membrane is of use in a proton exchange membrane fuel cell or an electrolyser.
