Disclosed is a catalyst complex for a fuel cell. The catalyst complex includes a support including carbon (C), platinum (Pt) supported on the support, and an iridium (Ir) compound supported on the support, and the iridium compound includes at least one of iridium oxide represented by Chemical Formula 1, IrO, and iridium-transition-metal oxide represented by Chemical Formula 2, IrMO, wherein M is a transition metal selected from the group consisting of Fe, Co, Cu, Ni and combinations thereof, and x is from 1 to 2.

A method for preparing acrylic acid, more specifically, to a method for preparing acrylic acid under a neutral condition at high yield in a short time without using a base, unlike the prior art in which a base is essentially used. The acrylic acid is produced using a supported catalyst having a specific composition when preparing acrylic acid by oxidation of allyl alcohol. Particularly, the preparation method can recover acrylic acid rather than acrylic acid salt as a final product, and thus has an advantage that the overall process cost can be reduced by eliminating essential processes in the prior art, such as ion exchange after the acidification process required for the conversion of acrylic acid salt to acrylic acid.
