StIm-AEM having an ion exchange capacity (IEC) of 0.54 mmol g1 with a grafting degree (GD) of B18%, possesses practical conductivity (450 mS/cm) even with a very low water uptake (10%) and high stability over\n600 h in a 1 M KOH solution at 80 1C. There exists a critical IEC (IECc) in the range of 0.7–0.8 mmol/g over which the membrane showed high water uptake, which resulted in pronounced susceptibility to hydrolysis. Using small-angle neutron scattering technique with a contrast variation method, we found\nthe hydrophilic phase in StIm-AEMs with IECs lower and higher than IECc shows ‘‘reverse-micelles’’ with water domains dispersed in the polymer matrix and ‘‘micelles’’ with graft polymer aggregates dispersed in the water matrix, respectively. The further analysis of micelle structures using the hard-sphere liquid model and Porod limit analysis reveals that the interfacial structures of ionic groups are essential for the electrochemical properties and durability of StIm-AEMs. In addition, StIm-AEM with an IEC of 0.95 mmol/g and the maximum power density of 80 mW/cm2 in the hydrazine hydrate fuel cell test, exhibited long-term durability under constant current (8.0 mA) up to 455 h, which, thus far, is the best durability at 80 C for platinum-free alkaline-type liquid fuel cells.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Royal Society of
