7. Insert the Plunger into the sleeve with the perforated plate pointing upwards.
8. Put the 18 mm diameter gas diffusion working-electrode onto the perforated plate inside
the sleeve.
9. Put the glass fiber separator onto the working-electrode and dispense a defined amount
of electrolyte on it. The optimum amount of electrolyte depends on the electrodes and
separator used. It has to be carefully determined in pre-tests. 0.5 cm3are a reasonable
amount for 1.5 mm thick glass fiber separator.
10. Put the counter electrode (18 mm diameter) on top of the cell stack.
11. Put the nickel current collector on top.
12. Slide the cell base over the assembly. Hold the components tightly together, then turn
the assembly back into the upright position.
13. Release the pressure applied on the cell stack. Mount the locking ring in order to align
the side opening of the cell base with the feed-through hole of the REF sleeve.
14. Replace the PTFE plug in the Cell base by the reference electrode.
15. Insert the PE seal and the spring.
16. Place the cell lid with the already attached siphon and transfer lines onto the cell base.
17. Put the cell into the bracket and tighten the wing nut.
18. Connect the inlet port to the gas supply and the outlet tube to the exhaust line.
5Disassembly and cleaning
Right after use, disassemble the cell in the reverse order of assembly.
Avoid removing or turning the contact screw beneath the cell base, as this could interrupt the
connection between feed wire and current collector.
All chemicals used have to be disposed properly. Clean wetted parts with water and/or other
appropriate solvent. Ultrasonic cleaning is recommended. After cleaning, all parts are to be
dried at 80°C in vacuum overnight. PE seal and PTFE ferrules are to be replaced.
