Baumgartner & Lamperstorfer Instruments GmbH B10930PWO-R/To 45 Abstract A highly efficient electrode, especially but not exclusively for an electrolyser for the generation of hydrogen, includes at least an electrically conductive plate, at least one layer of an electrically conductive mesh having knuckles in fused 5 electrical contact with the electrically conductive plate and mesh passages for the flow of an electrically conductive medium laterally through the mesh, as well as a porous layer of electrically conductive material coating a surface of the at least one layer of electrically conductive mesh remote from the conductive plate. The porous layer is in fused electrical contact with the mesh and has a planar surface 10 remote from the electrically conductive plate. A pore size of the porous layer is substantially smaller than a pore size of the mesh passages. 15.
