Sentence examples for gas diffusion coefficient from inspiring English sources

Hydrogen is a light and diffusible gas (diffusion coefficient of 0.61 cm2/s in air) [1] with a wide ranging inflammability (4% to 75%) [2].

In fuel cells, the gas diffusion coefficient, called the diffusivity, correlates with the concentration polarization (CP) energy loss and such important parameters associated with electrode materials as porosity and tortuosity.

In this case, the gas diffusion coefficient becomes (Singh et al. 2014) D_{text{n}} = frac{1}{3}du (4).

Using incremental gas diffusion coefficient, this model computes the gas filling time in a process similar to practical scenario.

However, the gas diffusion coefficient of CL is lower than MPL in spite of framework consisted of same carbon blacks.

Summary and suggestions are also provided for better understanding of gas diffusion phenomena and implementation of the effective gas diffusion coefficient models for fuel cell electrodes.

The gas diffusion coefficients for the single gamma phase and effective dual and phase structures are modeled separately, using the activation energy of the corresponding phase structure.

The most often used models in the open literature are reviewed and discussed focusing on the effective gas diffusion coefficients and tortuosity factors.

Effective gas diffusion coefficients were determined for twenty-six graphite specimens spanning six modern grades of nuclear graphite.

In order to make a good evaluation of the balance between gas generation and gas dissipation through engineered barriers and host formation, good estimates for the gas diffusion coefficients of the gases are needed.

One important feature of this model is that both the exchange current density and gas diffusion coefficients were dependent on the cell microstructures (porosity and pore size) and operational parameters (temperature, pressure and gas composition).
