Dotelli, "Investigation of hydrophobic treatments with perfluoropolyether derivatives of gas diffusion layers by electrochemical impedance spectroscopy in PEM-FC," Solid State Ionics, vol.
Nafion 117 membranes is sandwiched between the gas diffusion layers (GDL) and hot pressed to prepare the membrane electrode assembles (MEAs).
Finally, the limited gas transport in the gas diffusion layer is considered by the concentration loss term [[eta].sub.lim] [11].
The governing equations in the flow channel, gas diffusion layer, catalyst layer, and membrane are as follows:
Since it is directly attached to the gas diffusion layer, the seal makes it easier to assemble fuel cell stacks.
The model presented in this paper is a typical three-zone that consists of cathode-side gas flow channel, cathode-side gas diffusion layer and cathode-side catalyst layer.
The company said it will use the funds to develop a "next-generation fuel cell gas diffusion layer to be combined with its membrane technology for portable fuel cell applications."
In addition, the gases must not escape into the environment, and the hydrogen must not come into direct contact with the oxygen, making it essential to securely seal the gas diffusion layer. Seals also compensate for dimensional variations that may result from the expansion of adjacent components due to heat or other factors.
Some research studies reported a series of advantages regarding the effect of ratio w/a >1 on the PEMFC performance, like an enhanced mechanical support for membrane and Gas Diffusion Layer (GDL), higher water content in the membrane, improved ion conductivity of the membrane, improved heat transfer from membrane to GDL, uniform distribution of the current density and temperature across the membrane and improved performance at high current densities [17, 18].
Freudenberg's gas diffusion layers for e-cars are indispensable components for new mobility vehicles, he adds.
A third focuses on developing and optimizing electrodes for the archetypal kind of fuel cell--the PEM FC (proton exchange membrane fuel cell) and gas diffusion layers (GDLs), which help regulate their operation.
According to Ener1, project partners will collaborate in a number of areas, including the characterization, demonstration and evaluation of a novel membrane technology, fuel cell power generator demonstrations in India and Florida using locally produced biomass-derived fuels, and the development of gas diffusion layers for low-temperature PEM fuel cells.
