Disclosed is a linear conveyor for transporting glass panels in the vicinity of grinding stations or a washing station of a system for producing glass panel blanks including a linear conveyor, for example, a driven toothed belt, and opposite the driven toothed belt a beam, from which a fluid, in particular water, is discharged. The solid oxide fuel cell stack includes at least two solid oxide fuel cells. The traffic event may be a traffic burst exceeding a predetermined threshold. If the tension in, or the vibrational frequency of, the tensioned wire does not correspond to the desired value, the tension is further adjusted until the desired value is met. Also operating in the air conduit is a conical member which is actuated by a linear motor.
