“…Ilic et al [58] compared direct methanol fuel cells (DMFC) and lithium-ion batteries. They estimated that there is a need of time of about 7-12 years when DMFC can compete with lithium-ion batteries in terms of size, cost and overall performance.…”

“…Among the various types of fuel cells, Polymer Electrolyte Membrane (PEM) fuel cells have attracted most of the researchers because of their advantages like low emissions, low operating temperature and high power density and use of all solid state components, which make them suitable for portable applications [1][2][3][4]. Despite various advantages, the sluggish kinetics of ORR (oxygen reduction reaction) is the limiting factor for energy conversion in PEM fuel cells.…”

Multiwalled carbon nanotubes platinum nanocomposite has been prepared via chemical route by reduction of Pt salt on MWCNTs in ethylene glycol solution while refluxing in Argon atmosphere. The effect of different pH media during the reduction process on their physical and electrochemical properties, as well as on their performance in unit PEM fuel cell has been studied and further compared with the reaction carried out while refluxing in air as already demonstrated by the authors. The I-V performance of unit PEM fuel cell shows a peak Power density of 156 mW cm -2 with catalyst prepared in alkaline medium, an increase of [ 110 % as compared to 72 mW cm -2 obtained while employing catalyst prepared in acidic medium and tested under similar conditions. This is attributed not only to the small particle size of reduced Pt NPs, but also to its uniform distribution when reduction is carried out in alkaline medium. This has been further explained by detail reaction mechanism under alkaline conditions.

“…They are gaining importance because they use hydrogen as the energy source; moreover, they are clean and show far higher electric efficiency than other generator units. 2,3 Moreover, fuel cells are one of the most convenient energy sources at present where portable electronic products such as mobile phones and laptops have gained popularity among ordinary people owing to the rapid development of the modern electronics industry. Although portable electronic products are popular, the batteries used as power supplies for such products have not yet delivered satisfactory performance.…”

Zeolite-templated carbons (ZTCs), which have high specific surface area, were prepared by a conventional templating method using microporous zeolite-Y for catalyst supports in direct methanol fuel cells. The ZTCs were synthesized at different temperatures to investigate the characteristics of the surface produced and their electrochemical properties. Thereafter, Pt-Ru was deposited at different carbonization temperatures by a chemical reduction method. The crystalline and structural features were investigated using X-ray diffraction and scanning electron microscopy. The textural properties of the ZTCs were investigated by analyzing N 2 /77 K adsorption isotherms using the Brunauer-Emmett-Teller equation, while the micro-and meso-pore size distributions were analyzed using the Barrett-Joyner-Halenda and Harvarth-Kawazoe methods, respectively. The surface morphology was characterized using transmission electron microscopy and inductively coupled plasma-mass spectrometry. The electrochemical properties of the Pt-Ru/ZTCs catalysts were also analyzed by cyclic voltammetry measurements. From the results, the ZTCs carbonized at 900 °C show the highest specific surface areas. In addition, ZTC900-PR led to uniform dispersion of Pt-Ru on the ZTCs, which enhanced the electro-catalytic activity of the Pt-Ru catalysts. The particle size of ZTC900-PR catalyst is about 3.4 nm, also peak current density from the CV plot is 12.5 mA/cm 2 . Therefore, electro-catalytic activity of the ZTC900-PR catalyst is higher than those of ZTC1000-PR catalyst.
