Abstract EN
Nowadays, one of the major issues of the PEMFC concerns the durability.
Historically, carbon has been used as a catalyst support in PEMFC; nevertheless, under the environmental conditions of the cell, the carbon is oxidized, leaving the catalyst unsupported.
In order to increase the stability and durability of the catalyst in the PEMFC, a novel nanostructured metallic oxide support is proposed.
In this work, TiO2 was doped with Nb to obtain a material that combines chemical stability, high surface area, and an adequate electronic conductivity in order to be a successful catalyst support candidate for long-term PEMFC applications.
The TiO2-Nb nanostructured catalyst support was physically and electrochemically characterized.
According to the results, the TiO2-Nb offers high surface area and good particle dispersion; also, the electrochemical activity and stability of the support were evaluated under high potential conditions, where the TiO2-Nb proved to be much more stable than carbon.
