Abstract This paper measured the voltage of the hydrogen oxygen fuel cell and the decomposition voltage of electrolytic salt water recorded in the textbook. Then a micro fuel cell was designed using graphite sheets as electrodes, surrounded by filter paper soaked Na2SO4 solution as electrolyte solution. Activate the electrode by repeatedly charging and discharging to enhance the battery capacity. It can be combined with a droplet electrolysis cell for electrolyzing saturated salt water to form an integrated micro experiment.
