“…At the component level, different approaches to controlling water transport and removing water from PEMFCs have been described in literature, such as MEA design [3], control of hydrophilicity and microstructure of flow fields [4,5] or the insertion of a water management layer [6]. As the interface between the active areas and the flowfield backing, the gas diffusion layers (GDLs) are not only the key moderators for the different water transport phenomena but also, apart from the flowfields, the main site of water accumulation.…”

This study introduces a novel strategy for enhancing the performance of Polymer Electrolyte Fuel Cells at high current densities by means of an advanced gas diffusion layer design. The incorporation of hydrophilic wicking agents into microporous layers of the cathode gas diffusion layer improves water management, thus increasing the maximum power density of Polymer Electrolyte Fuel Cells. Ex-situ measurements with respect to water and vapour transport, and electrochemical polarisation data provide evidence suggesting that the beneficial effect has to be attributed to enhanced liquid water removal through the microporous layer.

“…182 MPL traits that lead to better performance include higher hydrophobicity, General models that compare strictly the difference in PEFC performance between having a MPL and not show that addition of a MPL leads to more uniform membrane hydration and gas and current distribution over the entirety of the PEFC. [192][193][194] One of the first MPL-specific works is that of Pasaogullari and Wang,195 who used a 1-D, half-cell, isothermal, and two-phase model to study the effects of MPL porosity, wettability, and thickness on performance. An interesting result stemmed from a comparison between their model and one that assumed a uniform gas pressure.…”

“…Experimental studies have shown that the presence of the MPL had a beneficial impact on the fuel cell performance (e.g., Qi and Kaufman 2002;Chen et al 2004;Kang et al 2010). The present study provides a piece of explanation in relation with the general problem of the water management in PEMFC.…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract This study builds upon previous work on single-layer invasion percolation in thin layers to incorporate a second layer with significantly different pore sizes and to study the impact of the resulting water configuration on gas-phase mass transport. We consider a situation where liquid water is injected at the assembly inlet through a series of independent injection points. The challenge is to ensure the transport of the liquid water while maintaining a good diffusive transport within the gas phase. The beneficial impact of the fine layer on the gas diffusion transport is shown. It is further shown that there exists a narrow range of fine layer thicknesses optimizing the gas transport. The results are discussed in relation with the water management issue in polymer electrolyte membrane fuel cells. Additional discussions, of more general interest in the context of thin porous system, are also offered.
