Cationic Polymers Developed for Alkaline Fuel Cell Applications
Abstract
Alkaline fuel cells (AFCs) recently have gained renewed interest because of their facile electrode reaction kinetics, reduced fuel crossover and better water management compared to their protonic fuel cell counterpart. The emerging anionic exchange membrane fuel cell (AEMFC) adopts cationic group-functionalized polymers as the solid electrolyte instead of liquid potassium hydroxide or sodium hydroxide used in the traditional AFC, avoiding leakage problems, bicarbonate and carbonate salt induced electrode degradation issues that accompany liquid electrolytes. The polymer electrolyte applied in fuel cells should have good mechanical properties as well as high thermal and chemical stabilities, considering the basic, humid and elevated temperature operating conditions and the constant start-ups and shutdowns in fuel cell operation.
