AvCarb Gas Diffusion Systems (GDS) combine carbon fiber paper, a PTFE treatment and a micro-porous layer surface coating, and are optimized for the rigorous demands PEM electrochemical cells. AvCarb has developed 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, and the same can be expected for electrolyzers. Applications include the formation of GDEs and protecting the membrane from the carbon fibers used in thicker transport layers. Additional details for these materials can be found by clicking the Properties or Datasheet tabs. A Selection Guide is under development.
