Poor mechanical property is a critical problem for phosphoric acid-doped high-temperature proton exchange membranes (HT-PEMs). In order to address this concern, in this work, a 3D network structural poly (aryl ether ketone)-polybenzimidazole (PAEK-cr-PBI) polymer electrolyte membrane was successfully synthesized through crosslinking reaction between poly (aryl ether ketone) with the pendant carboxyl group (PAEK-COOH) and amino-terminated polybenzimidazole (PBI-4NH2). PAEK-COOH with a poly (aryl ether ketone) backbone endows superior thermal, mechanical, and chemical stability, while PBI-4NH2 serves as both a proton conductor and a crosslinker with basic imidazole groups to absorb phosphoric acid. Moreover, the composite membrane of PAEK-cr-PBI blended with linear PBI (PAEK-cr-PBI@PBI) was also prepared. Both membranes with a proper phosphoric acid (PA) uptake exhibit an excellent proton conductivity of around 50 mS cm-1 at 170°C, which is comparable to that of the well-documented PA-doped PBI membrane. Furthermore, the PA-doped PAEK-cr-PBI membrane shows superior mechanical properties of 17 MPa compared with common PA-doped PBI. Based upon these encouraging results, the as-synthesized PAEK-cr-PBI gives a highly practical promise for its application in high-temperature proton exchange membrane fuel cells (HT-PEMFCs).

Abstract A polymer membrane as a proton exchange membrane (PEM) used in fuel cell is prepared by blending lignosulfonate (LS) from sulfite pulp industrial waste with sulphonated poly (ether ether ketone) (SPEEK). Different contents of LS ranging from 0 to 20% (w/w) were blended with SPEEK to measure the influence of LS content on performance of membrane. The results indicated that the proton conductivity of the prepared membrane was increased with the content of LS in membrane. For as-prepared membrane containing 15% LS, the proton conductivity is remarkably higher than that of membrane fabricated by sulfonated poly (aryl ether ketone) at the same test conditions. Nevertheless, the physical strength decreased as the LS content increased. Comprehensively, the blending membrane containing 15% LS can satisfy the PEM application, which implyes LS as a potential candidate for PEM application in a low temperature range.
