Porous salts for fuel cells Organic salts with high proton conductivity

Porous organic materials are potentially useful for many applications, including catalytic systems, separation processes, and gas storage. Although these framework-like structures vary greatly, they have one thing in common: their components are connected through covalent bonds. Porous organic salts, on the other hand, are a new class of materials with components held together by ionic bonds, the attractive forces between positive and negatively charged ions. They are challenging to produce because their pores usually collapse; the ionic bonds of previously known organic salts are not strong enough to stabilize a porous structure.
