Energy Project Preliminary Results

Procedure

1. Place a black plug into a 2x4cm length of rubber tube and insert the unplugged side into the top pin of the hydrogen side of the electrolyzer

2. Fill a syringe with distilled water and dispense it into another 2x4cm length of rubber tube inserted into the top pin on the oxygen side of the electrolyzer

3. Place a red plug into the rubber tube from step 2 and let the electrolyzer sit for 3 minutes

4. Fill the cylinders up to the zero line with distilled water

5. Place the inner containers into the cylinders

6. Connect rubber tubes to the top of each inner container

7. Connect the other end of one of the tubes from the step 5 to the bottom pin on the hydrogen side of the electrolyzer

8. Connect the other end of the other tube from step 5 to the bottom pin on the oxygen side of the electrolyzer

9. Attach the energy source to the top leads on the electrolyzer and turn the power on for 2 minutes. This produces the hydrogen and oxygen gases.

10. Place a clothespin on each tube connected to the inner containers to trap the gases in the inner containers

11. Use a hot plate to heat the cylinders or an ice bath to cool the cylinders to the desired temperature by measuring the temperature in of the distilled water in the cylinders with a thermometer (and assuming that the gases are at a similar temperature because the inner cylinder is surrounded by the distilled water

12. Keep the temperature stable at the target temperature for at least a minute to ensure that the temperature has evened out within the inner and outer cylinders

13. Attach the tubes to the PEM fuel cell

14. Attach leads from the voltage meter to the PEM fuel cell to measure and record the voltage

15. Repeat the entire procedure as necessary for the number of trials needed, at least 3 for each temperature

Results

Our experimental materials were not available on our first lab day, so we have not collected any data yet
