Permeability gas
WebOne of the components in the fuel cell is the gas diffusion layer, whose gas transport resistance contributes significantly to the power losses. The aim of this work is to break down the behavior in more detail and to show their physical dependencies. For this purpose, an existing measurement method for determining permeability will be ... WebThe permeability coefficient is a parameter defined as the transport flux of a gas (rate of gas permeation per unit area), per unit transmembrane driving force, per unit membrane thickness. The permeability coefficient for various gases and vapors in silicone is presented in the table below.

Webmembrane. Gas selectivity is the ratio of permeability coefficients of two gases (R A/B) P A/P B), where P A is the permeability of the more permeable gas and P B is the permeability of the less permeable gas in the binary gas pair. Polymers with both high permeability and selectivity are desirable. Higher permeability decreases the amount
