Seal arrangement for fuel cells

摘要

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.
