20140342266 | FUEL CELL INCLUDING COUPLING DEVICE - A fuel cell including a coupling device according to the present invention is configured such that a fastening member for fastening a manifold to a stack is coupled to the manifold in such a manner that the fastening member directly contacts the manifold thus enabling the stack and the manifold to be flexible in reacting to a difference in the thermal deformation between the stack and the manifold, the fastening member having a predetermined cross-sectional area such that the fastening member cannot be easily thermally deformed by an environmental change, thus minimizing a degradation of the binding force of the fastening member. Furthermore, a portion of a frame of a first coupled unit is coupled independently of other frames, and therefore, a degradation of a coupling force of a certain frame is preemptively prevented from affecting other frames even when the degradation occurs during the operation of the fuel cell, thus preventing the coupling between the stack and the manifold from consequently being degraded. As a result, a sudden degradation of the fuel cell performance is prevented. | 11-20-2014 |
