Abstract

Carbon black support is generally used for PEFC electrocatalysts, while their durability is an important technological issue caused by e.g. Carbon corrosion. Metal oxide supports have been studied as alternatives to carbon black. TiOj has also been considered as an alternative support material due to its stability under both cathode and anode conditions. Here, a Ti-based sheet-form electrode is developed, consisting of Pt electrocatalysts, and a porous metallic Ti sheet acting as both catalyst support and gas diffusion layer (GDL). Ti-based nanofibers with a diameter of several run were formed on the surface of the porous Ti sheet via NaOH treatment. Pt catalysts were successfully decorated on such nanostructure to construct a three-dimensional network structure in a carbon-free all-in-one electrode for PEFCs.
