“…At the next stage of carbon fiber production, carbonization, most of the non-carbon atoms are removed [28] by heating samples in an inert atmosphere from 623K to 1173-1973K. Structural evaluation of commercial PAN-based carbon fibers shows that carbonization at these temperatures results in low-order graphitic structure with small elongated graphitic crystals in amorphous carbon.…”

“…Phenolic resin was used as a low‐cost thermosetting resin that cross links to give high strength composite . High‐temperature treatment helps in aligning/graphitizing the carbon layers so as to achieve high electrical conductivity . The processing of the composite, especially high‐temperature heat treatment constitutes the major cost in the carbon paper development .…”

“…The carbon fiber‐based composite paper has been developed by the following method . Polyacrylonitrile‐based carbon fibers from Toray (grade T‐300) were used for preparing the macroporous preform . The carbon fibers were chopped in a definite length (0.7 ± 0.1 cm) and its calculated amount was uniformly dispersed in water using a suitable emulsifier and surfactant by means of an overhead mechanical stirrer as illustrated in Figure A and B .…”

Effect of matrix content on the performance of carbon paper as an electrode for PEMFC

Summary Porous conducting carbon fiber‐based composite paper is used as an electrode backing in the fuel cell assembly. It not only acts as a channel through which the reactant and product gases pass to and from the bipolar plate and the catalyst site but also helps in the flow of electrons. In order to perform its role efficiently, it should have sufficient strength, high electrical conductivity, and ideal porous structure. Carbon paper has been fabricated, which builds up the required composite properties. Studies have been conducted to optimize the fiber/matrix ratio in the carbon paper, while ensuring the perfect combination of porosity, mechanical strength, and electrical conductivity for an electrode in a proton electrolyte membrane fuel cells. Detail physico‐mechanical and electrochemical characterizations further ascertain that the fiber/matrix ratio plays an important role in tuning the composite properties. The polarization curve of the unit proton exchange membrane (PEM) fuel cell (with an effective electrode area 4 cm2) shows a peak power density of 916 mW/cm2 for the sample with fiber/matrix ratio of 65:35, which is almost the same as the commercially available sigracet gas diffusion layer (SGL) carbon paper tested under similar conditions. Further, proportionally enlarging the electrode area to 100 cm2 shows that the carbon paper not only shows almost repeatable results in a given set up but also scales up.
