“…In recent years, the hydrogen storage on metal organic framework's (MOFs) [3,[13][14][15], zeolite's [16,17] and carbon nanotubes [18][19][20][21][22][23][24][25], graphene [26][27][28] and activated carbons (ACs) have been reported in the literature by several groups. Among these ACs have proved to be one of the most promising adsorbent material for storage of hydrogen due to their availability, low cost and with tunable surface area.…”

Abstract. Activated carbons (ACs) are being used as energy storage material especially for hydrogen storage application. In the present work, AC materials were synthesized from jute fibers, activated and treated using KOH to increase the porosity of samples. These AC samples retained the fibrous structure even after chemical activation at high temperature of 700°C. Channel like structures were formed which helps to increase the hydrogen storage capacity. The surface area of these samples varied from 380 to 1220 m 2 /g due to carbonization and activation treatment. The sample with high surface area of 1224 m 2 /g showed a high hydrogen uptake capacity of 1.2 wt.% at 30°C and 40 bar of H 2 gas pressure. This sample also showed a high pore volume of 0.74 cm 3 /g. These results indicate that the raw material jute fibers can be used as hydrogen storage medium after thermal and chemical treatment which increases the surface area and micropore volume.

“…However, the mesoporous silicas and aluminosilicates [156,157] had very low hydrogen storage capacities of less than 0.5 wt%. Zeolites [148][149][150][151] and mesoporous carbon materials [158,160] had moderate hydrogen storage capacities but were still less than the target of 6.5 wt%. Mokaya and coworkers [152,154,155] prepared zeolite-templated carbons that possessed exceptional capacity to store hydrogen.…”

IntroductionZeolites and molecular sieves belong to an important class of natural and synthetic porous materials [1] that find important applications in many industrial processes including chemical separation and purification, chemical synthesis and fuel conversion, and pollution treatment and abatement [2][3][4]. The discovery of MCM-41 in 1992 [5, 6] has attracted research in the synthesis and applications of large pore molecular sieves including ordered mesoporous materials. The mesoporous materials display a greater range of pore sizes and compositions than typical zeolites and molecular sieves, and researches show that they are excellent catalyst, adsorbent, and membrane materials that have potential applications not only in traditional chemical processes but also in microelectronics, sensors, and agriculture [7-10].Fuel cell promises clean and efficient energy generation for stationary, mobile, and portable applications [11]. Striving for enhanced performance, zeolites and mesoporous materials are increasingly used in fuel cells. They were used to increase proton transport, decrease fuel crossover, and improve water management in the electrolyte membrane. They serve as electrode and electrocatalyst in the fuel cell and are also employed in fuel conversion, reforming, and storage. There are a number of excellent reviews on fuel cell electrolyte membranes [12][13][14][15][16][17] and electrode materials [18,19] in the literature, but none includes the recent uses of zeolites and molecular sieves. This chapter reviews the contributions of zeolites and molecular sieves in fuel cell research and is divided into three sections: (i) zeolites in electrolyte membrane, (ii) zeolites in fuel cell electrocatalysis, and (iii) zeolites in fuel processing for fuel cells. Zeolites in Electrolyte MembraneThe electrolyte membrane in a fuel cell separates the anode and cathode reactants and mediates the electrochemical reactions at the electrodes by rapid and selective

“…Hydrogen adsorption has been studied for a wide range of porous carbons, [40, silicas, [63,90] aluminas, [63] zeolites, [91][92][93][94][95][96][97] porous polymers, [98][99][100][101][102][103][104][105][106][107] COFs [108][109][110][111][112] and MOFs. [21,27,36,38,39,50,51,54,57,58, Hydrogen adsorption measurements for porous materials carried out at pressures up to 1 bar provide data for calculating the isosteric enthalpies of adsorption at zero surface coverage, which is a measure of the hydrogen surface interaction.…”

“…The amounts of hydrogen adsorbed under high pressure at 77 and 298 K and corresponding surface areas and pore volumes have been investigated for MOFs, [27,38,50,51,54,57,60,97,134,184] carbons, [80,83,[86][87][88]191] zeolites, [92][93][94][95]97] silicas, [90] polymers [98,100,103,104,106] and COFs [108] and correlations between hydrogen saturation (or close to saturation capacity at 77 K) and Langmuir surface area, BET surface area and total pore volumes are shown in Figures 4.8-4.10. It is evident that there are correlations between the hydrogen uptakes at high pressure and the porous structure parameters for the porous MOF materials.…”
