<p>The solid cathode comprises essentially a supporting element and, at least in the region of the cathode workface, an open-pore structure which is impregnated with aluminum and at least one of the transition metals from groups IV A, V A, and VI A of the Periodic Table of elements; this structure can be impregnated continuously from reserves of aluminide/aluminides. An open-pore structure which has shown itself to be particularly advantageous is one comprised of a carbon fibre felt pad some few millimetres thick.</p> |
