Abstract
Disclosed is a manifold block for a fuel cell, which provides excellent electrical insulation for a coolant flow channel in an internal flow channel. More specifically, a manifold block for a fuel cell stack, includes a coolant interface formed of a polymer insulating material and coolant flow channels; and a reactant gas interface formed of a metal material and including reactant gas flow channels. In particular, the reactant and coolant interfaces are mounted to a stack module and, at the same time, are integrally bonded to each other.
