transmission performance
Application:
PEM hydrogen production anode diffusion layer GDL
The anode diffusion layer is used for mass transfer of O2 and H2O
in environments with high potential and acidity, requiring coatings
with good corrosion resistance. The porous transport layer is
located between the catalytic layer and the bipolar plate, serving
as a pathway for water supply, gas emission, and electron
transport, directly affecting the concentration polarization and
Ohmic polarization of the water electrolysis reaction. The porous
transport layer should have a rich continuous pore structure that
is conducive to the diffusion and transfer of water and
precipitated gases, as well as good conductivity to reduce Ohmic
polarization. The anode side porous transport layer is generally
made of corrosion-resistant titanium porous material in high
potential acidic environments, and its surface can be treated with
precious metal coating to reduce contact resistance and service
life.
