Claim Text:
1. A manifold block for a fuel cell stack, the manifold block comprising: a coolant interface formed of a polymer insulating material and including a plurality of coolant flow channels; and a reactant gas interface formed of a moldable metal material and including a plurality of reactant gas flow channels, wherein the coolant interface and the reactant gas interface are mounted to a stack module of the fuel cell and, at the same time, integrally bonded to each other, wherein the coolant interface comprises a coolant inlet configured to supply coolant to the stack module and a coolant outlet configured to discharge the coolant from the stack module, the coolant inlet and the coolant outlet including flanges, each bonded to an opposite side of the stack module at an end of each of the plurality of coolant flow channels, wherein the flanges of the coolant interface comprise a plurality of flow channel apertures connected to the plurality of reactant gas flow channels of the reactant gas interface to serve as part of the plurality of reactant gas flow channels, wherein the reactant gas interface comprises flanges which are bonded to the flanges of the coolant interface at the ends of the plurality reactant gas flow channels, and wherein the flanges of the reactant gas interface comprise openings through which flow channel shape units of the coolant interface pass.
