Fuel cell system and method for providing electrical energy

The proposed invention relates to a fuel cell system (100) for providing electrical energy. The fuel cell system (100) comprises a blower (101) for conveying an anode gas, a motion sensor (103) for determining a measurement of a motion of an impeller of the blower (101), and a controller (105). The control unit (105) is configured to assign a state of a composition of matter in an anode circuit of the fuel cell system (100) to a measured value of the blower (101) using a predefined assignment scheme, and to assign the state of the composition of matter in the anode circuit of the fuel cell system (100) to the measured value of the blower (101). The measured value is determined by the motion sensor (103) in a rotational speed range between a starting rotational speed and a predetermined target rotational speed, and the fuel cell system (100) is adjusted as a function of the assigned state. 所提出的发明涉及一种用于提供电能的燃料电池系统(100)。所述燃料电池系统(100)包括鼓风机(101)、运动传感器(103)和控制器(105)，所述鼓风机用于输送阳极气体，所述运动传感器用于求取所述鼓风机(101)的叶轮的运动的测量值。所述控
