| Zusammenfassung: | The invention relates to a method (100) for operating a fuel cell (10) that comprises at least one individual cell (11) with a membrane (14) and catalysts (141, 142), wherein humidity (F) within the fuel cell is actively influenced (107, 111) as a function of a voltage (U) of the fuel cell (10), and the method further includes specifying (106) an initial humidity (F1) at an initial operating-point-related voltage (U1), and specifying (110) a second humidity (F2) that is lower than the first humidity (F1) at a second operating-point-related voltage (U2) that is higher than the first operating-point-related voltage (U1). Furthermore, the invention relates to a fuel cell system (1) that is configured to perform the method (100) according to the invention.
本发明涉及种用于运行燃料电池(10)的方法(100)，该燃料电池包括带有膜片(14)和催化剂(141,142)的至少个单个电池(11)，其中，主动影响(107,111)燃料电池内的湿度(F)取决于燃料电池(10)的电压(U)来实现，并且该方法还包括：在运行点相关的第电压(U1)情况下预设(106)第湿度(F1)，以及在高于运行点相关的第电压(U1)的运行点相关的第二电压(U2)的情况下预设(110)第二湿度(F2)，该第二湿度低于第湿度(F1)。此外，本发明涉及种燃料电池系统(1)，其设置成用于执行根据本发明的方法( |
