Synthesis of Facet-controlled PtNi Nanoparticles and Evaluation of Performance in PEM Fuel Cell

Article of Honda R&D Technical Review Vol.27 No.1

Summary

The research discussed in this paper set out to reduce the amount of Pt used in automotive polymer electrolyte fuel cells. Octahedral PtNi nanoparticles supported by carbon black (octahedral PtNi/C), which displays a high level of oxygen reduction reaction activity, was synthesized, and its effect in reducing the amount of Pt employed in an actual fuel cell was evaluated.
Performance tests of a fuel cell using the octahedral PtNi/C as a cathode material showed that Pt mass activity at 0.9 V was 3.4 times that of a market Pt catalyst. These results demonstrate that the octahedral PtNi/C is well suited as a catalyst material, displaying a high level of oxygen reduction reaction activity even in an actual fuel cell, and reducing the amount of Pt used in the cathodes by approximately 70%. The octahedral PtNi/C also displays good durability performance, with a rate of decline in mass activity of 19% after 10,000 0.6-0.9 V potential cycles, against 29% for the market Pt catalyst.
