AvCarb P75
Substrates are critical components of fuel cell membrane electrode assemblies (MEAs). AvCarb Gas Diffusion substrates are unparalleled in their ability to meet the rigorous demands of the fuel cell, including platinum catalyst and functional layer support, effective transport of gases and liquids, and conduction of heat and electricity. Moreover AvCarb substrates are highly durable, both chemically and mechanically.
