Abstract: The invention relates to an electrochemical cell which has an electrode, which may be either an anode or a cathode, and a membrane disposed in contact with one side of the electrode. An anode current bus is disposed on the other side of the anode, and a cathode current bus is disposed on the other side of the cathode. An anode current distributor collects current from an anode current bus and distributes it to the anode by electronic conduction, and a cathode current distributor collects current from the cathode and distributes it to the cathode bus by electronic conduction. The anode or the cathode current distributor is made of a metal which is treated by either nitriding, boriding or carbiding the metal in order to make the metal oxide growth resistant. Alternatively, the current distributor on the cathode side may be made of a nickel-based alloy. The current distributor thus provides a barrier between the current bus and the electrode, and the anolyte, catholyte and products of the cell.

Abstract: Process is disclosed for preparing a highly fluorinated alkane by contacting halogenated alkenes or alkanes with hydrogen fluoride in the presence of a catalyst which produces a super acid environment. Also, performing the fluorination process by using equipment having a corrosion resistant surface. The corrosion resistant surface may be provided by explosively cladding a corrosion resistant material onto a base metal.
