Definitions

  • the anode is typically cooled by the flow of a refrigerant fluid within the anode. It is therefore important that the surface area of the anode is as large as possible in order that effective heat exchange with the electrolyte may take place thereby ensuring efficient cooling of the anode. On the other hand a low anode surface area relative to that of the cathode is desirable in order that the anode current density may be high.
  • Figure 2 is a view in section along the line A-A in figure 1.
  • Figure 4 is a view in section through the cell of Figure 1 along the line C-C in figure 2
  • Figure 5 is a view in section along the line D-D in figure 3
  • electrolyte is charged tc the cell and the electrodes 10 and 14 are connected tc a source of electrical power (not shown) .
  • Air is pumped through tat- air chambers 12 by an air pump (not shown) , and a coolant fluid, for example a refrigerant, is caused to flow through the anode lumen 34 from a refrigeration system (not shown) externally of the cell.
  • a coolant fluid for example a refrigerant
