A fastening structure of a fuel cell stack according to the present invention is a structure in which a plurality of electrode plate groups, in which a plurality of electrode plates are stacked, are stacked. In a state in which the plurality of electrode plate groups separated by respectively stacking the plurality of electrode plates having two or more different structures, are formed, fastening force is dispersed by applying a distributed fastening method integrally formed by using a blocking plate disposed on upper and lower ends of a plurality of stacked electrode plate groups.

Dispersed fastening structure of fuel cell stack

A stack fastening structure of a fuel cell is provided and includes a fastening mechanism that is mounted at an outside of a plurality of stacked fuel cells to generate a force pressing against the plurality of stacked fuel cells. In addition, an insertion body is mounted within the fastening mechanism to adjust the force pressing against the plurality of fuel cells. Accordingly, the fastening force is more accurately adjusted using the insertion body and the external force applied to the insertion body is measured to calculate the fastening force.

A clamping device includes an oblique device and a unidirectional load control plate disposed on the outside of the fuel cell stack, not on the inside of the fuel cell stack. The device can automatically compensating the surface pressure in the fuel cell stack to be maintained constant, and provide a large clamping load with a small force using the load of the fuel cell stack.

Fuel cell stack clamping device

A device for clamping a fuel cell stack is provided to clamping a fuel cell stack easily by a large clamping load with small force and to maintain the internal bearing stress of a fuel cell stack to be constant. A device for clamping a fuel cell stack comprises an end plates(14) which has the vertical inner surface and the outer surface of a first oblique side(18) so as to be closely adhered to the both sides of a fuel cell stack; a oblique side device(10) which is in surface contact with the first oblique side and accommodates the end plate; and unidirectional load control boards(26,28) which are combined to the upper and lower sides of the end plate so as to allow the load of the fuel cell stack to be applied only to the inner direction of the stack.
