A reformer for a fuel cell and a fuel cell system including the same are shown. The reformer includes a heat source for providing heat to evaporate a mixed fuel and having a predetermined flow path length through which the mixed fuel passes and a catalyst layer lining the internal surface of the flow path, and a reforming reactor for generating hydrogen gas from the mixed fuel through a chemical catalytic reaction by the heat and having a predetermined flow path length through which the mixed fuel passes and a catalyst layer lining the internal surface of the flow path. Either the heat source, or the reforming reactor, or both are formed from an alloy of a barrier layer forming metal and a mechanical strength enhancing metal.
