Brennstoffzellen-Kennlinie und Wirkungsgrad

Characteristic and efficiency of fuel cellI. Principle In a electrolyser, the electrolyte consists of a porton-conducting membrane and water. When an electric voltage is applied, hydrogen and oxygen are formed. The fuel cell generates electrical energy from hydrogen and oxygen. The electrical properties of the electrolyser and the fuel cell are investigated by recording a current-voltage curve. To determine the efficiency, the gases are stored in small gasometers in order to be able to measure the quantities of the gases generated. II. Experiment 1. Get familiar with the working principle of the solar cells. 2. Measure the characteristic parameters of V-A Characteristic curve, open circuit voltage, short circuit current, max. output power and fill factor etc. of the solar cells. 3. Learning the working principle of proton exchange membrane water electrolyze (PEMWE) 4. Get familiar with the working principle of proton exchange membrane fuel cell (PEMFC) 5. Measure the V-A Characteristic curve, open circuit voltage, short circuit current, max. output power and transformation efficiency of fuel cell. 6. Observation of the energy transformation process: Luminous energy →solar cell →electrical energy →electrolyze →hydrogen →fuel cell →electrical energy
