Imidazolium Trifluoromethanesulfonate sPEEK Composites for Anhydrous High Temperature Proton Exchange Membrane Fuel Cells

Proton exchange membranes fuel cells (PEMFCs) are excellent energy carriers for numerous applications such as automobiles. Current standard operating conditions (<80°C) of PEMFCs are unfortunately optimized in a way that leads to catalyst poisoning by carbon monoxide. Higher operating temperatures (>120°C) are desirable, and can be achieved with alternative materials that conduct protons anhydrously via a Grotthuss mechanism. Alternative materials for an electrolyte would be ionic salts such as solid acids. Solid acids are chemically, thermally and electrochemically stable and …
