Abstract: |
The Pt-Ru/C catalyst is prepared through conversion of chloroplatinate into sulfite of Pt, reaction of water solution of sulfite of Pt and H2O2 to produce colloid solution of Pt, adding water solution of PuCl3 into the colloid solution under acid condition to form mixed Pt and Ru colloid solution, and adding carbon carrier after supersonic treatment into the mixed colloid solution. The catalyst of the present invention is used as electrode catalyst in fuel cell with proton exchange film and has still high catalytic activity in case of the CO content as high as 100 ppm. |
