Abstract
A separator for fuel cell is used for a fuel cell and is placed to face a membrane electrode assembly. The separator includes a separator center area placed to face a power generation area of the membrane electrode assembly; a peripheral region extended from the separator center area toward an outer edge; a cooling medium supply manifold and a cooling medium discharge manifold provided in the peripheral region; a fluid flow path area extended from the cooling medium supply manifold through the separator center area to the cooling medium discharge manifold; a sealing gasket provided in the peripheral region and placed to surround the fluid flow path area; and a gasket for peel test provided outside of the fluid flow path area and configured to receive an external force applied as a test for evaluation of an adhesive state of the gasket. Evaluating the adhesive state of the gasket for peel test improves the yield of products in manufacture of the separators for fuel cell.
