AvCarb Material Solutions products

AvCarb carbon fiber papers consist of high purity carbon fibers bonded together using a porous carbon matrix. Delivered on rolls, this material is used in demanding electrochemical applications including specialty batteries, fuel cells, and electrolyzers. AvCarb carbon fiber papers are unparalleled in their ability to meet the rigorous demands of electrochemical applications, including catalyst and microporous layer support, effective transport of gases and liquids, and conduction of heat and electricity in corrosive and high temperature environments. PTFE treated carbon fiber papers are available for applications in which liquid water repellency is required.

AvCarb Gas Diffusion Systems (GDS) combine carbon fiber paper, a PTFE treatment and micro-porous layer surface coating, and are optimized for the rigorous demands PEM fuel cell applications. AvCarb has developed both anode and cathode GDS materials to suit a wide variety of operating conditions (i.e. humidity levels, temperatures, current densities). Fuel cell manufacturers worldwide rely on AvCarb GDS products for consistent fuel cell performance and durability throughout the life of the fuel cell system. AvCarb has developed a broad range of solution for both mobile and stationary applications.

AvCarb® Molded Graphite Laminates (MGL) are superior carbon papers designed for electrolyzer and fuel cell applications. Available in stronger and thicker product formats than typical carbon papers, AvCarb® MGLs provide electrochemists with a highly durable electrode backing intended for harsh environments. With comparable property and performance data, MGL products can be used interchangeably with other industry standard carbon papers. Available in thicknesses ranging from 0.19mm to 0.37mm, these highly graphitic panels are manufactured under both heat and pressure. This process results in a carbon structure that is porous, gas permeable, and is electrochemically active. MGLs have been used for many years in both commercial and military applications around the world with new applications being developed every year.
