Abstract: The invention relates to system (1) for monitoring the environment of a motor vehicle (100), the system (1) comprising an image capture device (2) for sensing objects in the sensing region (E1), an illuminating device (3) for illuminating the sensing region (E1), and an environment sensing device (7) for sensing a part of the sensing region (E1) of the image capture device (2), wherein the system (1) is designed to classify, in terms of object type, an object situated in a sensing region of the at least one image capture device (2), when said object has been detected, and in each case to determine a confidence value, the so-called KO confidence value, “KO”, said KO indicating the probability that the object type of a detected object can be established, in particular correctly, by the image capture device (2), and wherein the system (1) is designed, when there is an object (OBJ) in the sensing region (E1), depending on the KO for the detected object (OBJ), or when the environment sensing device (7) detects the

Abstract: The present invention relates to a method for heating a fuel cell system (1a; 1b; 1c; 1d) comprising at least one fuel cell stack (2) with an anode portion (3) and a cathode portion (4), and a reformer (5) upstream of the anode portion (3) for steam reforming using a fuel, the reformer (5) comprising a nickel-based catalyst, said method having the following steps: starting a heating process for heating the fuel cell system (1a; 1b; 1c; 1d) with a heating device (6) and conducting a carbon-containing fluid and conducting steam through the nickel-based catalyst of the reformer (5) during the heating process. The invention also relates to a fuel cell system (1a; 1b; 1c; 1d) which is designed to carry out a method according to the invention.
