摘要：

Sulfonated poly(ether ether ketone)s (SPEEKs) were further substituted on the polymer main chain by amino groups to form an acid-basic polymer, and blended with acid polymeric Nafion (R) to create composite membranes. The acid-base blend membranes containing ionic crosslinking exhibited lower water uptake than recast Nafion (R), and the methanol permeability was reduced significantly for various contents of aminated SPEEK, with a maximum proton conductivity of similar to 0.063 S cm(-1) at 30 C. The single-cell performance of the blend membranes with various contents of aminated SPEEK showed 20-26 mW cm(-2) for S45A47 at 80 degrees C. Both the power density and open circuit voltage were higher than those of Nation (R) 115 and recast Nafion (R) The acid-base blend membranes satisfy the requirements for proton exchange membranes in the context of direct methanol fuel cell (DMFC) applications.
