The current energy crisis demands the development of new sustainable energy sources and devices with low environmental impact, including in the field of electrochemical cells. Mass transport limitations can reduce the overall performance of the device by l ...

To improve mass transport limitations in proton exchange membrane fuel cells (PEMFCs), a detailed analysis of the gas diffusion layer structure can aid to understand the transport processes of oxygen to the catalyst layer and the liquid water removal mecha ...

A microporous layer (MPL) is typically added to the gas diffusion layer of polymer electrolyte fuel cells (PEFCs) to promote cell performance and water management. The transport mechanism of the water through the MPL is, however, not well understood due to ...

Non-noble metal catalysts (NNMCs) are regarded as a promising alternative to the costly Pt-based materials required to catalyze the oxygen reduction reaction (ORR) in proton exchange membrane fuel cell (PEMFC) cathodes. However, the large diversity of NNMC ...

High activity and durability are two key requirements for the successful development of Pt-based ORR catalyst layers for polymer electrolyte fuel cell (PEFC) cathodes. Unsupported Pt-Ni aerogels consisting of an interconnected nanoparticle network have bee ...

Water management by gas diffusion electrodes is a fundamental aspect of the performance of electrochemical cells. Herein, we introduce the characteristic constrictions size as a descriptor for microporous layers (MPL). This parameter is calculated by volum ...
