    摘要: Fuel cell systems, e.g. systems including proton exchange membrane (PEM) fuel cells, are engineered to have more than one internal electrical resistance that can change according to temperature. Such changes in internal electrical resistance levels allow rapid heat-up of the fuel cells from low temperatures to an elevated temperature that is optimal for water management and fuel cell operation. The fuel cell systems can include at least one fuel cell and at least one resistor-switch unit electrically connected to the at least one fuel cell. The at least one resistor-switch unit includes a resistor and a switch in which the switch is electrically connected in parallel with the resistor.

    摘要: The invention relates to a fuel cell (1), comprising at least the following components: a proton-conducting polymer membrane (2) as the electrolyte; catalyst layers (3) covering the polymer membrane (2) on both sides; gas-permeable electrodes in the form of an anode (4) and a cathode (5), which lie adjacent to the surface of the catalyst layers (3) that faces outwards; electroconductive plates (6), which come into electroconductive contact with the electrodes in at short distances and which together with the electrodes, delimit channels carrying gas; and gas connections for supplying hydrogen (H2) and for supplying oxygen (O2). The inventive fuel cell (1) is characterised in that the polymer membrane (2) is a mixture based on a polymer blend containing at least one first polymer group A which is based on a halogenated and/or sulphonated polyalkene, and one second polymer group B which is based on a vulcanised rubber with a polar character.
