| 摘要 |
The invention relates to a method for closed-loop power control of a fuel cell system (2) in a vehicle (1), wherein the fuel cell system power (PFCS) is provided starting from a fuel cell system power (PVEH,soll) which is requested by the vehicle (1). The method according to the invention<b>characterized in that</b>the requested fuel cell system power (PVEH,soll) is converted into a power request (PFC,soll) made of the fuel cell (3) by an expected power (PAUX,Soll) of auxiliary drives (10) of the fuel cell system (2) at the requested fuel cell system power (PVEH,soll) being added to the requested fuel cell system power (PVEH,soll), and in that a media supply of the fuel cell (3) which corresponds to the power request (PFC,soli) made of the fuel cell (3) is requested, wherein the electrical loading of the fuel cell (3) with current (IFC) is performed in accordance with a model (21) of the cathode dynamics in such a way that a control variable of the closed-loop control operation is matched to the media dynamics, and in that the power release is performed such that the fuel cell (3) is loaded only when the adequate media supply is ensured. |
