“…Discrete domains of ion-conducting phases are inappropriate for charge transport, so introducing ordered ionic domains in the membranes is essential to attain improvement in the transport properties of PEFCs [30][31][32][33][34] . There are a few elegant studies on the ionic conductivity of polymerized ILs that explore the effect of the length of the spacers between the polymer backbone and the ionic moiety 17,33,34 . However, the reported ionic conductivities are low when compared with composite membranes due to the restricted motions of the ionic moiety.…”

Proton exchange fuel cells (PEFCs) have the potential to provide power for a variety of applications ranging from electronic devices to transportation vehicles. A major challenge towards economically viable PEFCs is finding an electrolyte that is both durable and easily passes protons. In this article, we study novel anhydrous proton-conducting membranes, formed by incorporating ionic liquids into synthetic block co-polymer electrolytes, poly(styrenesulphonate-b-methylbutylene) (s n mB m ), as high-temperature PEFCs. The resulting membranes are transparent, flexible and thermally stable up to 180 °C. The increases in the sulphonation level of s n mB m co-polymers (proton supplier) and the concentration of the ionic liquid (proton mediator) produce an overall increase in conductivity. morphology effects were studied by X-ray scattering and electron microscopy. Compared with membranes having discrete ionic domains (including nafion 117), the nanostructured membranes revealed over an order of magnitude increase in conductivity with the highest conductivity of 0.045 s cm − 1 obtained at 165 °C.

“…The synthesis of polymer electrolytes S. Yu and coworkers (Yu et al, 2008) reported the first example of polymerization of microemulsions comprising surfactant stabilized ionic liquid nanodomains. Polymerization of these ionic liquid-based microemulsions yielded free-standing, flexible, and transparent polymer electrolytes even though the resulting vinyl polymers are incompatible with ionic liquid cores.…”
