摘要 |
The invention relates to a method to improve the usability of a fuel cell system and to improve the control of its heating, said fuel cell system (1) comprising at least one fuel cell unit (5), which includes at least one fuel cell stack (55) whose fuel cells (2) include an anode side (7), a cathode side (8) and an electrolyte (9) interposed there between. In the method, a gas flow (10) to be supplied to the anode side (7) is heated by means of thermal energy contained in a gas flowing into the fuel cell unit (5) onto the cathode side (8). The invention relates also to a fuel cell system arrangement applying the method. |
