“…Because of its vital role in fuel cell performance, much effort has been directed towards optimizing its properties. [3][4][5][6][7][8][9][10][11] Porous conducting carbon paper has been identied as one of the most promising material as the electrode substrate/gas diffusion layer (GDL) support, not only because of its high conductivity that allows easy ow of electrons but also because of its ne porosity that allows uniform distribution of the reactant gases over its surface.…”

Porous conducting carbon paper has been identified as one of the most suitable materials to be used as a fuel cell electrode backing. Carbon paper is prepared by the combined process of papermaking followed by composite formation. Experiments have been carried out whereby heat treated multiwalled carbon nanotubes (MWCNTs) are integrated in the sample while keeping the amount of fiber and resin constant.The diminutive magnitudes of these nanostructures are found to have a considerable effect on the electrical and mechanical properties of the carbon paper electrode. The I-V performance of the unit polymer electrolyte membrane (PEM) fuel cell shows a maximum power density of 880 mW cm À2 with 0.05 vol% of MWCNTs, an increase of $25% as compared to 700 mW cm À2 obtained using commercially available standard Toray carbon paper tested under similar conditions.

“…The cathode oxygen reduction reaction (ORR) and anode hydrogen oxidation reaction (HOR) both occur on the surfaces of Pt-based catalysts with pure water and heat as the only by-products. The catalyst performance is, therefore, very decisive to the fuel cell functioning and much effort has been guided towards its optimization [4][5][6]. Cost and durability are other major concerns in the commercialization of fuel cells.…”

Pristine multiwalled carbon nanotube supported platinum catalyst (Pt/CNT) has been developed by reduction of Pt salt on CNTs in ethylene glycol solution. The reactions were carried out under different pH conditions followed by detailed physical and electrochemical characterizations. The I-V performance of unit Polymer electrolyte membrane fuel cell shows a peak Power density of 325 mWcm -2 with catalyst prepared in alkaline medium, an increase of [250 % as compared to 87 mWcm -2 obtained, while employing catalyst prepared in acidic medium and tested under similar conditions. This is attributed not only to the uniform distribution of Pt nanoparticles with small particle size in range of 2-3 nm, but also to the metallic or zero oxidation state in which most of the Pt is present when reduction is carried out in alkaline medium.

“…The chopped fibers are soaked in water and a binder, typically polyvinyl alcohol [93], followed by a drying step. The coated fibers are impregnated with a resin and subjected to a pre-curing step at 150-175 C [94]. A number of resins can be used, being the phenolic resin the most common because of its carbon structure, good adherence, and its low cost [94,95].…”

Carbon materials are fundamental for the manufacturing of fuel cells. Several fuel cell components are made entirely of carbon in a graphitic form. In the present chapter, an overview of the different fuel cell carbon components and the materials used in their preparation will be presented. Novel approaches in the synthetic method, in order to impart desired properties, and in the manufacturing of the components will be shown. Also, relevant results on the latest research conducted will be discussed.
