Evaluation of metal nitrides and borides as alternative electrocatalyst support materials for polymer electrolyte fuel cells
… Poor durability is mainly attributed to carbon support corrosion during start-up and shut-down of the fuel cell. Corrosion of the electrocatalyst support materials has numerous adverse effects on the performance of the fuel cell, such as weakening of metal-support interaction which results in Pt …

Conductive Si doped metal oxide fuel cell catalyst supports: understanding the role of Si content
… cell (PEMFC) catalysts commonly use platinum supported on carbon (Pt/C) which is susceptible to corrosion, thus a highly conductive and stable Ti3O5 doped by Si (TOS) conductive metal oxide catalyst support is reported. The TOS support was optimized for 20 wt% Si and surface area. The support …
