Abstract: A method for preparing a platinum-indium cluster catalyst for a fuel cell, the method including steps of: obtaining a carbon powder, dispersing the carbon powder in a strong oxidizing solution, and performing high-temperature hydrothermal treatment to obtain an activated carbon powder; obtaining a mixed alcohol solution comprising a platinum precursor and an indium precursor; dispersing the activated carbon powder in the mixed alcohol solution, and heat treating the mixed alcohol solution to volatilize an alcohol solvent to obtain a mixed powder; and performing high-temperature treatment on the mixed powder under a mixed gas atmosphere of hydrogen and argon, to yield a platinum-indium cluster catalyst for a fuel cell.
