This new PEM (proton exchange membrane) fuel cell stack enables up to four cells to be connected either in series or in parallel. The fuel cell stack is operated wih hydrogen H₂ and oxygen O₂ or air. The hydrogen and oxygen react at the polymer membrane to form water, releasing electrical energy in the process. When four fuel cells are connected in series, the fuel cell stack generates a no-load voltage of approx. 3.6 V and a maximum power of 5 watts. These high voltage and power values are sufficient to e.g. power standard lamp types (e.g. halogen lamps).
