dc.description.abstract | The carbon material mainly used as a support material in proton exchange membrane fuel cells (PEMFCs) has a critical limitation-the corrosion reaction of carbon by a water-electrolysis reaction during PEMFC operation. To overcome this corrosion problem, transition metal oxides have recently been proposed as a next-generation support material to replace carbon materials. However, the low electrical conductivity of transition metal oxides leads to a negative effect on the electrochemical performance of PEMFCs. Therefore, in this study, titanium suboxide (TSO) with a crystalline phase of reduced transition metal oxide and high electrical conductivity was synthesized using a combined catalytic and thermal reduction reaction. In particular, the TSO material synthesized at a temperature of 900 degrees C was confirmed to exhibit a single Ti4O7 phase and electrical conductivity 10(5)-10(6) times higher than that of bare TiO2. Furthermore, TSO exhibits superior electrochemical durability against corrosion reaction via a water-electrolysis reaction during PEMFC operation. | - |
