First step of the fuel cell assembly is the preparation of the flexible plastic tubing. Cut
(2) 3cm long pieces and connect one to both of the pressure relief valves. Then cut a
12cm long pieces and connect to both of the 20ml syringes for storing hydrogen and
oxygen. Finally, cut a 5cm long piece of flexible plastic tubing and connect to the 5ml
syringe for injecting the water.
Step 1 – Hydrating the Membrane
The membrane of the fuel cell can by hydradted by adding distilled water (regular water
can damage the fuel cell) to the Oxygen side of the fuel cell. Start by drawing ~1mL of
distilled water into a syringe and inject the distilled water into the bottom nozzle on the
Oxygen side of the fuel cell (some water might leak from the top nozzle). Never operate
the fuel cell without insuring that there is water in the oxygen side. Once filled, remove
the syringe and attach a pressure relief valvue to this nozzle.
Next, attach a pressure relief valve to the lower nozzle on the Hydrogen side. It‘s important
to note that this side should be kept dry so check and make sure the tubing is dry!
