This review article surveys the use of zeolites and me soporous materials in fuel cell device and, operations. Zeolites are increasingly used to modify and improve the fuel cell membrane to address the, problems of fuel crossover and membrane stability. Mesoporous carbons and carbon aerogels with, their large surface area, high porosity and good interconnectivity are considered ideal material for electrodes and electrocatalysts. Zeolites and mesoporous materials are also employed as template to create nano-, micro- and macro-scale structures for new electrocatalysts. Furthermore, zeolites are used as catalyst, adsorbent and membrane in fuel processing from hydrogen production to purification. (C) 2013 Published by Elsevier B.V.
