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.

Abstract: The collecting plate of the present invention is used in a stacked fuel cell, and comprises a collecting section and an output terminal that is electrically connected to the collecting section and has a thickness that is greater than the thickness of the collecting section. For example, the output terminal is formed by bending at least part of an output terminal forming portion that is extended from the collecting section, at least one time.

Abstract: A seal arrangement for a fuel cell structure is provided which includes a seal portion in the form of a gasket between adjacent fuel cells in a stack of fuel cells. In the seal arrangement, a portion of the fuel cell structure that overlaps the gasket as viewed in a direction of lamination of the cells has a constant-thickness structure having a substantially constant thickness. The seal arrangement may further be arranged to seal fuel cell coolant passages and manifolds from fuel cell gas passages.
