The at least one support is structured as a heat-conducting element made of a material with a thermal conductivity of A>5 W/(m-K) and is arranged transversely to the spacing direction.
The invention relates to a method for operating a fuel cell system, comprising a cooling circuit for cooling at least one fuel cell, wherein a coolant circulating in the cooling circuit is cooled with a coolant cooler, which also has air flowing through it. The air is supplied by a fan assembly. The fuel cell system also comprises an evaporative cooling unit, which, upstream of the coolant cooler, introduces water into the air supplied by the fan assembly. An increased efficiency of the fuel cell system alongside sufficient cooling of the at least one fuel cell is achieved in that the evaporative cooling unit introduces water at a maximum rate before the fan assembly reaches its maximum air mass flow. The invention also relates to a fuel cell system of this type, as well as a motor vehicle comprising a fuel cell system of this type.

A calibrating tool may include a clamping sleeve and a fixing ring. The clamping sleeve may include a plurality of radially displaceable clamping jaws extending in a finger-like manner in an axial direction. The plurality of clamping jaws may each have a free end and a conically outwardly widening outer surface disposed at the free end. The fixing ring may be arranged on the clamping sleeve in an axially displaceable manner. The fixing ring may have a conical internal surface area. The plurality of clamping jaws may move radially inwards when the fixing ring is pushed on and the conical internal surface area of the fixing ring is in contact with the conically outwardly widening-external outer surface of each of the plurality of clamping jaws.
