Poly(arylene ether ketone) was synthesized containing pendant carboxylic groups which can easily produce a series of Cross-linked Sulfonated Poly(arylene ether ketone). In order to limit the harmful degradation of sulfonate groups on the main chain makes it more stable on working condition, sulfonate groups were only attached on the diamino cross-linker and pendant amino naphthalene. In addition, sulfonated cross-linker was utilized to enhance proton conductivity, mechanical properties and lower the water uptake. Proton conductivity, water uptake, mechanical properties, thermal stability and cell performance were investigated to evaluate the properties of the CSPAEK membranes for fuel cell application. |
