Summary: In order to address the dependence on fossil fuels and global warming issues, research has focused on developing eco-friendly energy conversion devices. Polymer electrolyte membranes (PEMs), as a key component in PEMFCs, should have high proton conductivity and excellent physicochemical stability. Incorporating organic/inorganic fillers into the polymer matrix is an effective method to control the properties of the PEM.

Summary: This review summarizes recent progress and developments on per-fluorinated and non-fluorinated membranes with carbon nanotubes (CNTs) as reinforced fillers in various key areas. The topics reviewed include the correlation between the mechanical stability, thermal stability, water retention capacity, and proton conductivity of different membranes with different functionalized CNTs. In addition, it presents the preparation strategies of membrane matrix and CNTs filler, as well as the reinforced mechanism of CNTs in the membrane. Furthermore, the impact of interactions between CNTs and various types of PEM is discussed to provide a deeper perspective. Finally, the strategy for improving the performance of PEM and the challenges of CNTs-based membranes are analyzed for prospects.

Summary: Super inorganic proton conductor boron phosphate (BPO4) was synthesized and coated on multi-walled carbon nanotubes (MWNTs) through a sol-gel method with polydopamine (PDA) assistance, resulting in BPO4@MWNTs. Then, BPO4@MWNTs were dispersed in dilute chitosan (CTS) solution to prepare CTS/BPO4@MWNTs composite membranes. The well-dispersed BPO4@MWNTs and optimized interface compatibility between BPO4@MWNTs and CTS matrix contributed to the superior performances of CTS/BPO4@MWNTs composite membranes in terms of thermal stability, mechanical property, oxidation stability, proton conductivity, and power density.

Summary: This study presents composite membranes made of cellulose nanocrystals and a protic ionic liquid, which exhibit improved proton conductivity of biopolymers under high temperature and anhydrous conditions. The membranes display good thermal stability and ionic conductivity, with analysis showing that the properties are influenced by defects, twisting, and aggregation of nanocrystals at the nanoscale. Preliminary fuel cell tests demonstrate that the membranes respond to H-2 gas and generate electrical current, laying a solid groundwork for further development of biopolymer/protic ionic liquid electrolytes for energy applications.
