“…A rolling technique, by which a colloidal dispersion is cast onto a carbon paper substrate, increased the catalytic activity of a Pt/Ru catalyst. [106,107] A vapour-fed methanol fuel cell minimises the cross-over effect (Section 2.3.4) and can improve the overall performance of the cell in combination with GDEs. Using a liquid feed arrangement simplifies the design, as no humidification system is necessary.…”

“…Proton exchange membrane fuel cells (PEMFC) are promising candidates for the applications in the fields of aerospace, energy and traffic, due to their high‐energy conversion efficiency and good performance at low temperature 1–8. Proton exchange membrane (PEM) is the key component of the PEMFC because of its proton conductivity and its role in the separation of the gas and electrodes.…”

Through sol‐gel reactions, a series of sulfonated poly(ether ether ketone) (SPEEK)/TiO2 hybrid membranes with various contents of nano‐sized TiO2 particles were prepared and characterized. It was found that with the increasing of the TiO2 contents in the hybrid membranes, the water uptake and water retention increased. Meanwhile, the introduction of inorganic particles reduced the methanol permeability. The proton conductivity was enhanced by introduction of hydrophilic inorganic particles into the SPEEK membranes, which might be an effective approach to increase the working temperature of PEM. © 2008 Wiley Periodicals, Inc.

“…The conventional impregnation method has been widely adopted as an effective method for the preparation of high surface area due to its simplicity in preparing Pt/C and PtRu/C carbon supported electrocatalysts [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60]. Conventional preparation techniques based on wet impregnation involve impregnation of the support with noble metal precursor salts that are subsequently reduced by reducing agents or a gaseous reducing environment.…”
