Топливный элемент Характеристика и эффективность

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.
