The experimental results of a study on CO tolerant anodes for PEFC are presented. Anodes prepared with different carbon supported platinum alloys were tested in a 50 cm2 single cell, using as cathodes low platinum loading (0.1 mg/cm2) electrodes. The obtained results indicate that the performances are temperature dependent, and they have a remarkable increase in the range from 70 to 90°C. The carbon supported Pt-Ru alloy with atomic ratio 1:1 seems to be the most promising anode catalyst for H2/CO fuel in PEFCs at low temperature.

Abstract
The experimental results of a study on CO tolerant anodes for PEFC are presented. Anodes prepared with different carbon supported platinum alloys were tested in a 50 cm2 single cell, using as cathodes low platinum loading (0.1 mg/cm2) electrodes. The obtained results indicate that the performances are temperature dependent, and they have a remarkable increase in the range from 70 to 90°C. The carbon supported Pt-Ru alloy with atomic ratio 1:1 seems to be the most promising anode catalyst for H2/CO fuel in PEFCs at low temperature.File in questo prodotto:
