Paraphrasing - Essay Example The pumping station will be self-sufficient and require no external power to pump the water to the reservoir tank. Fuel Cell is a system that can transfer the chemical energy to electrical energy. That means to convert the reaction between hydrogen and oxygen to get electricity. These processes do not produce any air pollution. Hydrogen gas helps a lot in the pump station, because it can produce energy by reacting in fuel cell with oxygen to produce electricity. It acts as a basic material in this Remote Pumping Station System Project because it can generate power. The context diagram (Figure 3 in Attachment) gives the necessary information that we need to calculate to redesign the project. This diagram makes it easier to find out which formula we are going to use in calculations. Experiment 1 (Table1 in Attachment) was to determine the angle of the solar panel. We used the load measurement box of the rotary switch. We set the protractor handout at angel 0. Then we adjusted the solar to the lamp. We had to consider the distance between the solar and the lamp like 50 cm. After that, we wrote down the current (A) in CW (+) and CCW (-) in different angles between 0 and 90 by turning the solar. Experiment 2 (Table 2 in Attachment) we were able to measure the amount of hydrogen created by the electrolyte. We observed the level of hydrogen created, after each 2 ml increment on the cylinder; we wrote down the time it took to reach this increment with the current and voltage. We continued writing down the time until 10 ml of hydrogen was produced. Experiment 3(Table 3 in Attachment) was to determine the fuel cell consumption efficiency. This experiment looked like experiment 2, both of them done by creating hydrogen. When hydrogen had reached 10 ml, the light source turned off. In this time, their would be the electrolyzer storage gas in the storage cylinder. We used several formulas to get the right data for this project. The first calculation was
