FUEL CELL SYSTEM, SEPARATOR LAYERED PRODUCT, AND FUEL CELL STACK

摘要

PROBLEM TO BE SOLVED: To miniaturize a mechanism for collecting a fluid leaked from a fuel cell stack.

SOLUTION: A first peripheral gasket 71b and a third cooling water gasket 71d are mounted outside a first hydrogen gasket 71a and a third cooling water gasket 71c formed so as to surround regions for circulating hydrogen gas and cooling water therethrough between adjacent separators 12a and 12b. Leakage gas detection manifolds 61 and leakage water detection manifolds 62 piercing the separators 12a and 12b are formed in regions A and B surrounded by the gaskets 71a and 71c and the gaskets 71b and 71d. In addition, a hydrogen detector and a level sensor for detecting hydrogen gas and cooling water leaked from the detection manifolds 61 and 62 are installed.
