Protic Ionic Liquids in Contrast to Aprotic Analogs: Transport Properties and Electrochemical Reactivity

open access: yesThe Chemical Record, EarlyView.
The transport properties and electrochemical reactivity of protic ionic liquids (ILs) are compared with those of aprotic analogs. Protic ILs are characterized by strong cation–anion hydrogen bonding and labile protons, enabling proton conduction and highlighting their potential as fuel cell electrolytes.

PEM Fuel Cell Degradation

open access: yesECS Transactions, 2010
The durability of PEM fuel cells is a major barrier to the commercialization of these systems for stationary and transportation power applications. While significant progress has been made in understanding degradation mechanisms and improving materials, further improvements in durability are required to meet commercialization targets.
