A. Characteristic Curve of the Electrolyzer Figure 1: Apparatus for characteristic curve of electrolyzer The procedure for this experiment is described below: 1. Set up the apparatus as shown in Figure 1 make sure all connections have the correct polarity. Figure 1 connections Power Supply Connections: - Connect the red terminal of the power supply to the red terminal of the electrolyzer. - Connect the black terminal of the power supply to the black terminal of the load box's ammeter. Electrolyzer connections - Connect black terminal of the elelctrolyzer to the red terminal of the load box's ammeter. - Connect the red terminal of the electrolyzer to the red terminal of the load box's voltmeter. - Connect the black terminal of the electrolyzer to the black terminal of the load box's voltmeter. 2. Fill the electrolyzer cylinders (after sealing them) with distilled water to the 0ml mark. 3. The distance between the lamp and the solar module should be around 1020cm. 4. Adjust the rotary switch of the load measurement box to "SHORT CIRCUIT". 5. Adjust the current of the solar module by varying the light intensity (e.g. by rotating the solar module to different angles with respect to the incident light). Record different current values, starting from small current values, (e.g. 0.01 A to 0.35A or 10mA to 350mA, depending on the type of lamp). 6. Record the electrolyzer's voltage and current, fill your data into the following table 1 (at least 8 sets of measurements). (Note: No bubble or few bubbles will appear during the step.) Table 1 DO NOT LET THE CURRENT EXCEED 0.5 A, IT WILL DAMAGE THE ELECTROLYZER. Evaluation 1. Plot the current-voltage (IV) characteristic curve of the electrolyzer, with current as the Y axis. An example was given as below (Figure 2). 2. Interpret the characteristic curve of the electrolyzer 3. Answer to the following questions: a. What is the value of the voltage at which the current starts to flow? b. Define the term polarization voltage. What is the polarization voltage in this case? c. Why there is no current before 1V ? d. Define the term decomposition voltage. What is the decomposition voltage in this case? e. Define the term overpotential. What is the value of the overpotential at this case
