he awareness of global climate change by emissions of greenhouse gases from fossil fuel combustion is widely known by current
society. Polymer Electrolyte Fuel cell (PEFC) technology has been a very promising clean technology with high efficiency that has
been used in a wide range of portable, automotive and stationary applications. The fuel cell research has been developing very rapidly
and successfully in the last few years. However, some issues remain largely unresolved, namely water management and the high cost
of the PEFC component. One of the efficient and cost-effective ways to improve the design of the PEFC and consequently resolve the
above-mentioned issues is through modeling. However, the built PEFC models need to be fed with accurate transport coefficients to
enhance their productivity. One of the most important transport coefficients is the gas permeability of the PEFC porous media which
highly affects the convective flow. Therefore, experimental studies have been conducted to investigate the gas permeability of the gas
diffusion media used in PEFCs. The focus has been on the effects of the following on the gas permeability of the gas diffusion layers
(GDLs): (i) type of carbon black used in the microporous layers (MPL) attached to the GDL, (ii) carbon and polytetrafluoroethylene
(PTFE) loading, and (iii) the thickness of the MPL. Further, a novel method has been proposed to estimate the penetration of the MPL
into the carbon substrate (i.e. the GDL before being coated with the MPL ink). Also, the effect of sintering on the gas permeability of
the MPL has been investigated for the first time.
