Abstract
A method for manufacturing a catalyst for a fuel cell can include provision of a platinum precursor and a carbon material. The platinum precursor and the carbon material can be mixed to form a platinum carbon mixture. The platinum carbon mixture can be heated to form a porous solid. The porous solid can be milled to form a powder. The powder can be reacted with a reducing agent to form the catalyst.
