| 摘要 |
The invention relates to a fuel cell system (1) based on solid oxide fuel cells, comprising at least one fuel cell (5) which has at least one inlet (4) and at least one outlet (10). A fuel cell exhaust gas (12) is conducted from the outlet (10) to a first heat exchanger (20) arranged in a heating circuit (22) for a heat carrier medium, and the fuel cell system (1) has a feedback for a condensate of the fuel cell exhaust gas (12). The aim of the invention is a long service life of the fuel cells with little work, expenditure, and technical complexity. This is achieved in that the fuel cell system (1) has a second heat exchanger (19) for controlling the temperature of the fuel cell exhaust gas (12) or the heat carrier medium of the heating circuit (22), said second heat exchanger being connected to an air supply line (15). In the process, the temperature of the fuel cell exhaust gas (12) or of the heat carrier medium of the heating circuit (22), said gas and medium being connected via the first heat exchanger (20) so as to exchange heat, is adjusted in the second heat exchanger (19) using air. |
