A definitive version was subsequently published in Renewable Energy, [VOL 50 (2013) AbstractThe present study focuses on the investigation of water dynamics inside a polymer electrolyte membrane fuel cell using two different modelling approaches: Eulerian two-phase mixture and volume of fluid interface tracking models. The Eulerian twophase mixture model has provided overall information of species distribution inside a fuel cell and identified that the liquid water usually accumulates under the land area.

The Bruggeman model has traditionally been used to represent the diffusion of species in the porous gas diffusion layer. In the present study, the Bruggeman model has been compared against models based on particle porous media, multi-length scale particles and the percolation type correlation. 1 NUMERICAL STUDY OF THE EFFECT OF EFFECTIVE DIFFUSIVITY AND PERMEABILITY OF THE GAS DIFFUSION LAYER ON FUEL CELL PERFORMANCEThe effects of isotropic and anisotropic permeability on flow dynamics and fuel cell performance have also been investigated. The present study shows that the modelling of the effective diffusivity has significant effects on the fuel cell performance prediction. The percolation based anisotropic model provides better accuracy for the fuel cell performance prediction. The effects of permeability have been found to be negligible and the specification of any realistic value for permeability has been found to be sufficient for polymer electrolyte membrane fuel cell modelling.

Three-dimensional simulations were performed for proton exchange membrane fuel cell (PEMFC) with thin catalyst-coated membrane (CCM) regarding liquid water cooling design. The studied PEMFC follows a counter-flow pattern for the H 2 and air stream, which is commonly adopted in today's automotive PEMFCs. For the thermal modeling of the liquid water, conjugate heat transfer model is used. The cooling flow inlet temperature between 60 and 75 C, direction, flow rate between 0.08 and 0.32 L s À1 m À2 as well as the cooling channel number are investigated, specifically. It is found that the cooling inlet temperature directly determines the working temperature of PEMFC under the same cooling flow rate. It means that increasing the cooling inlet temperature can lift the PEMFC operating temperature. The co-direction for the liquid flow and the air stream is found to be better for PEMFC as it can suppress the liquid water formed near cathode outlet. It is then pointed out that the cooling flow rate would determine the along-channel temperature non-uniformity in PEMFC and moderate flow rate is preferred. Reducing the number of the cooling channels while assigning higher flow rate for each channel will slightly lift the PEMFC temperature overall, but this strategy will result in more pumping power loss.
