1. Introduction Carbon-supported platinum catalysts used for the cathode of present polymer electrolyte fuel cells (PEFCs) have some problems such as a large amount of platinum use and low durability under operation condition. Therefore, we have atte

To obtain an ideal electrocatalysts for hydrogen fuel cells, we investigated group 4 and 5 oxide-based compounds because of their high degree of freedom. First-principles calculations revealed that oxide surfaces such as those of titanium oxide could

To develop highly active and durable non-Pt cathodes, group 4 and 5 oxide-based compounds were employed. First-principles calculations revealed that oxide surfaces such as those of titanium oxide and zirconium oxide can break down the universal scali
