Structure and Chemistry of Nafion-H: A Fluorinated Sulfonic Acid Polymer

Chitosan-based electrolyte composite membranesII. Mechanical properties and ionic conductivity

“…6, the dry Chit-3 (see Table 1 for its KOH content) composite membrane possesses a tensile strength of around 35 MPa, which is an adequate tensile strength value for fuel cell operation [29,30]. The obtained results from Figs.…”

Synthesis, Characterization and Ionic Conductive Properties of Phosphorylated Chitosan Membranes

“…43 MPa. [24,25] In spite of their superior characteristics for PEFCs, these membranes do have some weak points. [26] They are strongly limited to the range of temperature over which they can be reliably used.…”

Well-defined block copolymer ionomers and their blend membranes for proton exchange membrane fuel cell

“…Macromolecular structures leading to a phase-segregated morphology are promising materials for PEMFC since the microstructure and morphology of proton conducting polymers play an important role on ionic conductivity and mechanical strength of membranes [4,5]. Nafion TM , a perflourinated polymer having vinyl ether side chains terminating with sulfonic acid groups, provides an excellent proton transport arising from its unique nanophase-separated morphology [6][7][8]. However, Nafion TM has still some drawbacks such as its considerably high cost and synthetic difficulty especially when compared to other promising proton conducting polymers.…”
