| 摘要 |
The invention relates to a fuel cell module (12) consisting of a cell stack (1) with end plates (13, 14 ) on the anode and cathode side and having a tensioning system (17) and media connections (30-35) for oxygen, hydrogen and coolant. The module also comprises several single cells (7i, 7i+1, 7i+2), each having a membrane-electrode unit (10), said units consisting of an electrode anode and an electrode cathode (5, 6), made of a porous, gas-permeable material and an electrolyte membrane (2) with an anode and cathode catalyst (3,4) and being provided with current collectors (15, 16) on the anode and cathode sides. The module is characterised in that the media supply lines (30, 31, 32) and the media drain lines (33, 34, 35) are associated with a cooling and medium module (40), that said cooling and medium module (40) is exclusively designed to provide secondary functional chambers (42, 43, 44) and to form the stack and that either the hydrogen electrode (5, 5') or the oxygen electrode (6, 6') of the membrane-electrode unit (10) of the neighbouring single cell (7i, 7i+1, 7i+2) is situated on either side of a respective cooling and medium module (40). |
