Part 6. Experiments
Sunlight powered water electrolysis using the electrolyzer function of the reversible fuel cell
Insert the reversible fuel cell (C) into the slot located on the reversible fuel cell base (O) (see A).
Use scissors to cut out two lengths of 2cm of rubber tubing from the long rubber tube (G) provided in the
kit. Place the black pin (I) into one end of the 2cm rubber tube.
Attach the short rubber tube with the black pin to the top nozzle on the hydrogen side of the reversible fuel
cell (marked H2). Attach the other short rubber tube to the top nozzle on the oxygen side of the reversible
fuel cell (marked O2) and place the red pin (I) aside (see B).
Note: Good ion conductivity is critical to the performance of the reversible fuel cell. In order to ensure good
conductivity, the reversible fuel cell’s membrane needs to be properly humidified.
In order to humidify the reversible fuel cell, complete the following three steps:
Find the syringe (J) and push in its plunger in to remove all air inside. Draw distilled water into the syringe.
On the reversible fuel cell (C), insert firmly the syringe (J) nozzle into the upper nozzle tube on the oxygen side.
Slowly push the plunger to let the water into the oxygen side of the reversible fuel cell (see C).
