Abstract
This study focuses on the role of the combined gas diffusion layer and membrane on thermal diffusion coefficient and its effects on water transport in polymer electrolyte membrane fuel cell. Thermal diffusion coefficients were reported for water in typical membrane-electrode assemblies. Gas diffusion layers and, in some cases, microporous layers, surrounded the membrane in the center. The sign of the coefficient depended on the materials used. While the Teflon-coated and microporous layer-containing Sigracet 10BC type gas diffusion layer has positive coefficients, the Sigracet type 10BA and 10AA without such microporous layer have negative coefficients. The thermal diffusion coefficient has an activation energy, supporting the idea of water movement by activated jumps. We conclude that hydrophobic layers may significantly improve water and heat transport away from the cathode, and this is why reversible heat transfer should not be neglected in fuel cell studies. • The thermal diffusion coefficient has a negative sign in hydrophilic and a positive sign in hydrophobic layers. • The thermal diffusion coefficient of a MEA is significantly influenced by the microporous layer. • There is a clear Arrhenius behavior with temperature for the thermal diffusion coefficient of a MEA. • The heat of transfer has a non-negligible effect on the heat flux out of the MEA layers.
