Ion transport in CLIP: Investigation through conductivity and NMR measurements

Proton-conducting ionic liquid-based Proton Exchange Membrane Fuel Cell membranes: The key role of ionomer–ionic liquid interaction

“…For free ions and solvent-separated ion pairs, the Nernst-Einstein equation may be used to forecast ionic conductivity, calc , from the diffusion coefficients of the cation and anion. This approach was already used in the previous paper of Iojoiu et al [16].…”

“…This domain has since aroused a great deal of interest with a view to application in HT-PEMFCs [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

Ionic Liquids and Their Hosting by Polymers for HT‐PEMFC Membranes

“…This might be explained (1) by the flexibility induced by the ether function, and (2) by the interaction between the oxygen lone pair and the ammonium. Indeed, the latter decreases the positive charge on nitrogen and, therefore, decreases ion-ion interactions [17,25]. Furthermore, the inter-and/or intra-molecular interactions between the ether function and the positive charge might generate a higher local disorder.…”

“…For PCILs based on cyclic aliphatic ammoniums (17)(18)(19)(20)(21)(22)(23), the melting temperatures (T m ) are higher than those of their acyclic aliphatic ammonium homologues (for example 17 vs. 4). Furthermore, the T m of five-membered heterocycles e.g.…”

“…The PCIL syntheses were performed following the protocol described in previous publication [17][18][19][20][21].…”
