“…The thermal conductivity of the GDLs has strong influence on the membrane temperature and hence on activation losses or the current distribution, indicating a significant role played by lateral heat conduction [55]. In recent years a number of researchers have investigated the GDL thermal conductivity [52,53,[55][56][57][58][59][60][61].…”

Abstract:In an effort to reduce the environmental impact of the energy sector that is mostly based on fossil fuels, researchers are looking for a clean alternative of our existing energy sources. Hydrogen Energy and Fuel Cells, and in particular Polymer Electrolyte Membrane Fuel Cells (PEMFCs) have emerged as a leading candidate for transportation as well as stationary and portable applications. Due to the irreversibility of the electrochemical reactions and ohmic heating in the fuel cell components, the PEMFC produces a significant amount of heat and this heat has to be removed in order to avoid cell or stack overheating. In this paper, a review of the key heat transfer mechanisms and the various cooling strategies that are available for heat removal from PEMFCs are presented. Due to the interrelated nature and difficulty of conducting in-situ thermal measurements on the operating PEMFCs, computational modelling provides a fast and efficient way of designing PEMFC cooling systems and understanding the heat transfer mechanisms. Therefore PEMFC thermal modelling is also highlighted together with present challenges and potential areas for further research and development works.

“…Zamel et al [58] used the thermal capacitance method to experimentally measure the through-plane thermal conductivity of TORAY carbon paper in a temperature range from 50 ∘ C to 120 ∘ C [58]. They also investigated the effects of compression and PTFE loading on the overall thermal conductivity.…”

“…5. The next important knowledge development was in-plane thermal conductivity (6)(7)(8). Depending on compaction pressure, the difference between in-plane and through-plane thermal conductivity was readily proposed and interpreted in thermal models because it is similar for the electric thermal conductivity (9).…”

“…Changes in temperature lead to changes in thermal conductivity for GDLs. These were measured both for in-and through-plane thermal conductivity by Zamel et al (8). It is the knowledge from points 1. and 2. that were available to Bapat and Thynell (16) and Kandlikar and Li (17) for their reviews of heat conduction effects in PEM fuel cells in 2007 and thermal management in PEM fuel cell stacks in 2009, respectively.…”

“…For the PTL, the in-plane and through-plane thermal conductivities are different. Because the in-plane electrical conductivity is several times larger than the through-plane electrical conductivity, it was first postulated (22,23) and later verified experimentally (6,8) that the in-plane thermal conductivities are five to ten times larger than the through-plane ones (mainly depending on the GDL compaction).…”

Experimental Study of Thermal Conductivity and Compression Measurements of the GDL-MPL Interfacial Composite Region

MPL and GDL in a PEM fuel cell assembly are often treated as separate layers in the literature. However, there exists a considerable interfacial region where the two different materials merge. The MPL consists of fine carbon particles, a binder and a solvent that is applied on top of the fibrous GDL. In the process of coating, the MPL intrudes into the GDL and forms an MPL-GDL-composite region. This region has properties that differ from either of the materials that it consists of. Through-plane thermal conductivity and thickness variation under different compaction pressures were measured for such a composite region of commercial gas diffusion layer (GDL), Freudenberg H1410, and custom-made MPL. Thermal conductivity at 9.2 bar compaction pressure for GDL only is 0.111 ± 0.009 W K-1 m-1, for MPL only 0.08 ± 0.02 W K-1 m-1, and for the composite region is 0.124 ± 0.005 W K-1 m-1. X-Ray Computed Tomography images of the materials ascertain the level of penetration for the MPL into the GDL.
