Heating system with fuel cell arragement and method of operating a fuel cell arragement

The heating system has a fuel cell device (12) and a cooling device (22) for the fuel cell device. A latent heat storage device (34) is coupled to a cooling circuit (24) and a heating circuit (42) is coupled to the latent heat storage device. A heating medium is passed through the latent heat storage device to acquire heat. The latent heat storage device is connected after the coolant output of the fuel cell device. An independent claim is also included for the following: (a) a method of operating a fuel cell system.
