Abstract

It has been realized an instrument of generating electric power by using a series of Cu-Zn electrode and two different electrolyte types, that are pure seawaterand seawater that has been filtered and added sodium bicarbonate (NaHCO3). The instrument is designed  to do charging and discharging seawater electrolyte manually. Electrolyte cell consist of 20 cell with 20 pairs of copper and zinc electrodes arranged in series. The instrument measurements are measuring the illumination of LED 3 watts and mass of zinc electrode. The Instrument was testedfor 72 hours  with three times electrolyte charging every 24 hours. The result showed that the illumination were generated by instrument with both of electrolyte will decrease by time. The seawater was filtered and added NaHCO3 can turn on  3 wattsLED longer than the pure seawater.On the third day, corrosion rate of  zinc electrode with pure seawater electrolyte is 9 times higher than seawater was filtered and added NaHCO3.
