Abstract: A fuel cell stack has a prevention dam formed outside an alignment pin such that a sealing material, which has viscosity and fluidity at a sealing temperature of a fuel cell, may be prevented from coming into contact with and adhering to the alignment pin, and pressure applied from the outside may be uniformly applied to the fuel cell stack.

Abstract: In the present disclosure, there is provided a polyethylene in which the high molecular region ratio in the molecular structure is lowered, and the viscosity and melt index are optimized with a narrow molecular weight distribution. Therefore, it is possible to prevent premature cross-linking of chlorinated polyethylene obtained by reacting the polyethylene with chlorine, thereby minimizing a decrease in viscosity even after long-term storage and improving extrusion processability. Further, there is provided a vulcanizable chlorinated polyethylene composition using the polyethylene.
