Estimating the term…
A method for a frost start of a fuel cell device having a fuel cell stack, in which a plurality of fuel cells electrically switched in series is pressed by a compression force of a clamping device between two end plates, comprises determining the presence of frost start conditions, reducing the compression force by means of the clamping device, and operating the fuel cells in a frost start operation, in which a compression force acting on the fuel cells of the fuel cell stack and reduced as compared to that of a normal operation is maintained. A fuel cell device as well as a motor vehicle having a fuel cell device with a controller adapted to carry out such a method for a frost start of the fuel cell device are also provided.
A method for a frost start of a fuel cell device having a fuel cell stack, in which a plurality of fuel cells electrically switched in series is pressed by a compression force of a clamping device between two end plates, and having a controller which is adapted to carry out the method for the frost start of the fuel cell device, the method comprising:
A fuel cell device having an adjustable clamping device for setting the compression force on fuel cells stacked between two end plates, and having a controller which is adapted to carry out a method for a frost start of the fuel cell device, the method comprising:
