The fuel cell that used salt water as its fuel really surprised me. According to the results and trends in the graph, the energy that the fuel cell was giving off was higher than that of the tap water, but then quickly dropped off. I had hypothesized that the salt water would not do so well because of the extra salt molecules within the solution that might have slowed down the process. I was at the same time right and wrong, because the voltage started off high, but then quickly dropped. I think this is because the salt in the water made it possible for more h20 molecules to be broken down into hydrogen and oxygen atoms. This overload of fuel in the fuel cell lead to the bloated voltage being output by the fuel cell. The reason it dropped so quickly is that the fuel ran out. I think that the salt might have special characteristics that might have affected the platinum in such a way as to make the hydrogen get used up all at once and the result being an explosion of energy that was quickly put out, instead of it being regulated, and used constantly, like in the case of the tap water.
