Proton-conducting electrolyte membranes based on aromatic condensation polymers

Sulfonated Aromatic Polyethers Containing Pyridine Units as Electrolytes for High Temperature Fuel Cells

“…Introducing ionic groups onto the polymer backbone using sulfonated monomers is another approach that allows better control of the sulfonation degree (SD) and homogeneous distribution of ionic groups over the polymer chain. Rusanov et al reviewed the development of sulfonated polymers [9,10], while Lee et al paid special attention to sulfonated block copolymers which have advantageous properties [11]. In many cases, sulfonated aromatic polymers exhibit high proton conductivities and fulfill the required properties for fuel cell applications.…”

Proton-Exchanging Electrolyte Membranes Based on Aromatic Condensation Polymers

“…A number of reviews concerning the development of proton-conducting membranes based on polymer electrolytes are available [1,7,8,[31][32][33]. They contain information on the advanced materials, their electrochemical properties, water uptake and thermal stabilities.…”

Polymeric organic–inorganic proton-exchange membranes for fuel cells produced by the sol–gel method

“…Hydrogen and alcohols, mostly methanol, are used as fuels in such electrochemical generators [1- 4,8]. Hydrogen PEMFCs are used for power supply in large-scale stationary and nonstationary objects [2,4,12], while methanol PEMFCs are mainly used as power supplies for portable electronics [5,6].…”

“…High efficiency coupled with environmental safety makes fuel cells some of the most promising alternative methods of energy production [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In recent times among the well known types of fuel cells special attention has been attracted to polymer electrolyte membrane fuel cells (PEMFC)s [1 -16].…”
