摘要： A polymer electrolyte fuel cell-use gasket, included in a polymer electrolyte fuel cell including a fuel cell stack. In fuel cell stack, a plurality of unit cell modules is stacked, and each of the unit cell modules includes sealing members disposed at circumference portions of both surfaces of a membrane electrode assembly (9), and paired separators (10A) (10B) sandwiching the membrane electrode assembly and the sealing members. The fuel cell stack is assembled by being clamped by a fastening member via paired end plates respectively disposed at both ends of a stackedproduct. The present invention relates to the polymer electrolyte fuel cell-use gasket (14) in which the sealing members are integrally molded with the circumference portions of both surfaces of the membrane electrode assembly. A conventional gasket has an issue that the gasket can not achieve, at the same time, the conflicting demands, i.e., a reduction in the fastening force and a sure securing of the sealing performance. In the present invention, the issue is resolved by as the sealing member of the gasket, two rows of sealing lips (15) (16) continuously provided in parallel to each other in an in-plane manner, and at least an outer one of the two rows of sealing lips is integrally formed having a top side bell-shaped portion overlaid on a bottom side bell-shaped portion.
