Abstract
AbstractNowadays, the research of proton conductive materials has been extended from traditional sulfonated polymers to novel crystalline solid materials. It is important but still challenging to develop high‐performance proton‐conducting materials suitable for proton exchange membrane fuel cells (PEMFCs). Considering the features of molybdenum oxide and triazole in the construction of proton‐conducting material, two triazole‐modified molybdenum oxides, [MoO3(trz)0.5] 1 and [H(atrz)4[(atrz)2(γ‐Mo8O26)] ⋅ 2H2O 2 (trz=1,2,4‐triazole, atrz=3‐amino‐1,2,4‐triazole), were re‐synthesized under optimized synthetic conditions, and their proton‐conducting performances were investigated. 1 and 2 show high proton conductivities of 1.94×10−2 S cm−1 (85 °C, 95 % RH) and 1.3×10−3 S cm−1 (65 °C, 95 % RH), respectively.
