Manifold block for fuel cell stack

The present invention relates to a manifold block for the fuel cell stack, there is provided a manifold block for the fuel cell stack that has superior electrical insulation can be secured to the cooling water flow with no insulating coating. To achieve the above object, the present invention provides a manifold block coupled to a fuel cell stack modules and having a gas flow path and the cooling medium flow path, the inner side cooling medium flow path by being inserted into the inside of the cooling medium flow path in close contact with the inner surface cooling water flow and a tubular insulating member for electric insulation; Being in close contact with the inner surface of the cooling medium flow path is inserted into the inner insulating member insulating and protective cover for fixing the insulating member, provides a manifold block for the fuel cell stack comprising: a.
