A2.7.1.1 Ogniwa paliwowe
| Our experimental equipment for this topic also includes new PEM fuel cells (PEM = Proton Exchange Membrane) built into the vehicle. The hydrogen (H2) is initially split into H atoms at a catalytically active electrode. After losing an electron (- pole) the proton H+ goes through the polymer membrane to the oxygen side, where water is produced as a result of electron gain (+ pole): O2 + 4 H+ + 4 e- => 2 H2O.
Higher voltages are necessary for driving motors. Therefore, like for the battery, many (currently about 200) elements, each of about 1 volt, must be connected in series close to the so-called stack. Since the corresponding energy is not completely consumed directly, a battery is necessary for intermediate storage. However, it can be significantly smaller than for a pure electric drive, for example.
