Summary
In this work, sulfonated diblock copolymers (SDBCs) were prepared by polycondensation of sulfonated poly(ether-ether-ketone) (SPEEK) and hydrophobic oligomer, which were combined with sintered anatase titanium oxide (S-An-TiO2) to create a hybrid membrane for apply in proton exchange membrane fuel cells (PEMFCs) operating with low relative humidity (RH). Then, a series of composite membranes (SDBC/S-An-TiO2) were prepared by varying the wt% of S-An-TiO2 blended with SDBC. The results showed that appropriate quantity (ie, 15 wt%) of S-An-TiO2 can significantly improve the proton conductivity and physiochemical properties of prepared composite membrane, as well as the PEMFC performance and durability under 20% RH. The 1.5 wt% of SDBC/S-An-TiO2 offers high current output, power output, and durability values at 60°C under 20% RH, which are 0.207 A cm−2, 0.074 W cm−2 and over 90 hours, respectively. These results can be attributed to the good interfacial compatibility between S-An-TiO2 and SDBC.
