In fuels cells, hydrogen “burns“ with oxygen to form water. The hydrogen and oxygen molecules are ionized at catalytically activated electrodes. In the process hydrogen loses electrons which are taken up by oxygen. The simulation shows this “original principle" of the fuel cell and explains (graphically and in the form of an animation) a modern membrane fuel cell with polymer membrane, a so-called PEM fuel cell. Its use in power plants is presented.
