Abstract

A gas diffusion electrode comprises a cloth (12) of activated carbon fibers having a first face coated in a hydrophobic material (14) and a second face on which particles of catalyst (16) are fixed directly and are dispersed in substantially uniform manner over the fibers. The electrode can be used in an electrochemical cell of a proton exchange membrane fuel-cell battery, or in an electrochemical reactor, e.g. for making chlorine and caustic soda.
