SEAL STRUCTURE FOR FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a seal structure capable of preventing mixing of different types of fluid even by occurrence of a local defect such as breakage in a seal line. SOLUTION: In this seal structure for the fuel cell, at least one seal line in a gasket line 51 between modules and a seal line 52 between separators is doubled in a part between flow passages of different types of fluid seal lines separated for every fluid flow passage of each fluid by doubling are formed of a material anti-corrosive against a fluid to which the seal lines are brought into contact. In a gas communication part 53 communicating a manifold with a reaction face inside, a backup structure 54 pressing the separator between the modules is arranged in a part corresponding to the cell lamination direction.
