Acrylic fiber bonded carbon fiber paper as gas diffusion media for fuel cell |
摘要 |
A gas diffusion media for a fuel cell, such as a proton exchange membrane fuel cell, is provided. The gas diffusion media includes carbonizable acrylic pulp fibers instead of conventional phenolic resin as a binder material. The acrylic fibers are mixed with the carbon fiber dispersion during the papermaking step, thus eliminating the phenolic resin impregnation step typically associated with conventional gas diffusion media manufacturing processes. The mat is then cured and carbonized to produce gas diffusion media.
