| 摘要 |
The invention relates to a fuel cell system comprising a number of polymer electrolyte membrane individual fuel cells (2), which are arranged one above the other to form a stack (3). According to the invention, an intermediate space (10) for accommodating a cooling medium is provided between adjacent individual fuel cells (2) or adjacent individual fuel cells (2) are delimite d by bipolar plates (7), which comprise passages (12) for receiving a cooling medium. In addition, cooling medium distribution spaces (15) and cooling medium collection spaces (18) are arranged on the lateral surfaces (23) of t he stack. In order to cool the fuel cell system (1), cooling medium flows into a cooling medium distribution space (15) through the intermediate spaces situated between the individual fuel cells or through the passages located i n the bipolar plates and, finally, the cooling medium flows into the cooling medium collection space from which it leaves the fuel cell system. |
