Preparation of the Electrolyzer Module and Wind
Powered Hydrogen Production
Insert the reversible fuel cell, terminals on top, into the slot on the base. Cut 2 x 4cm
length pieces of rubber tube and insert a black pin into the end of one tube. Place
the tube with the black pin into the top pin on the hydrogen side (with black terminal).
Place the other tube firmly onto the top input nozzle on the oxygen side.
Fill the syringe with DISTILED water. On the red oxygen side of the electrolyzer,
connect the syringe to the uncapped tube. Fill the reversible fuel cell until water
begins to flow out of the tube. Attach a red plug to the Oxygen side tube. Let settle
for 3 min.
Attach the round cylinders to the cylinder base by pressing downward into round
slots and twisting into place. Then add water up to the "0" line.
Place inner containers into outer cylinders minding that the gaps are not blocked by inner plastic rims. Make sure the water is still level to
the “0” line. If not, remove some water with the syringe so that water level is at “0” line. Cut the remaining piece of long tubing into two
pieces of approximately 20 cm length. Connect the two pieces of tubing to the top nozzles on the inner containers. If the tubing is
connected to the inner cylinders last there will be no air trapped inside the inner containers.
Connect the other end of the long tube on the hydrogen side to the bottom end of the black hydrogen side of the reversible fuel cell.
Connect the other end of the long tube on the oxygen side to the bottom end of the red oxygen side of the reversible fuel cell.
