| | Abstract | I am studying the subject of “clean” energy. Therefore I have decided to |
| | find out what are more efficient, fuel cells, or solar cells. It is my |
| | hypothesis that fuel cells are the more efficient of the two. To test this I |
| | took one fuel cell and one solar cell, and then after providing each with the |
| | necessary products they need to work, be it light or hydrogen and |
| | oxygen, I took readings of the electrical output from both for a certain time |
| | period, checking both at even intervals. For a result I found that the fuel |
| | cell had on average73.52% efficiency, at least on voltage. The solar cell |
| | had a 12.86% average efficiency. So in conclusion the fuel cell is most |
| | definitely more efficient than the solar cell. |
