Separator assembly for fuel cell and fuel cell stack including same

Abstract

Provided is a separator assembly for a fuel cell and a fuel cell stack including the same that are capable of strengthening a surface pressure of a surface pressure weakening point formed between an inner airtight line and an outer airtight line. A separator assembly according to an exemplary embodiment of the present disclosure is configured such that a pair of separators are bonded together and are stacked on each other while facing each other with a sub-gasket that surrounds and supports a membrane electrode assembly therebetween, and includes a first separator, and a second separator having a cooling airtight line, an inner airtight line, and an outer airtight line, wherein at least one support forming a surface pressure is provided in a region between the inner airtight line and the outer airtight line of the second separator.
