    Abstract: The present invention relates to a sealing structure for polymer electrolyte fuel cell, which comprises a bipolar plate with sealing groove to be filled with rubber using a dispenser, and a gasket interposed between the bipolar plate and a membrane electrode assembly. That is, according to the present invention, the thickness deviation in a gasket can be softened by interposing a gasket between a rubber ands a membrane electrode assembly after filling rubber in a sealing groove formed on a bipolar plate using a dispenser. Also, nonuniform stress distribution can be resolved because a gasket covers with a pressure despite the height deviation of rubber, and a stress is not directly transmitted to a membrane electrode assembly and dispersed by a gasket despite nonuniform stress distribution.

    Abstract translation: 本发明涉及用于聚合物电解质燃料电池的密封结构，其包括具有密封槽的双极板，其使用分配器填充橡胶，以及插入在双极板和膜电极组件之间的垫圈。 也就是说，根据本发明，通过在使用分配器在形成在双极板上的密封槽中填充橡胶之后，在橡胶和膜电极组件之间插入垫圈，可以软化垫圈中的厚度偏差。 此外，由于尽管橡胶的高度偏差，垫圈覆盖有垫圈，并且应力不会直接传递到膜电极组件并且通过垫圈分散，尽管存在不均匀的应力分布，但是可以解决不均匀的应力分布。
