Fractal Modeling of Gas Transport in Gas Diffusion Layers (GDLs) for Enhanced Electrochemical Performance of PEMFCs

Enonsi Augustin Leode, Gabin Koto N’Gobi, Clément Kouchade, Basile Kounouhewa

Proton exchange membrane fuel cells (PEMFCs) are among the most promising technologies for advancing the energy transition, particularly in clean transportation and decentralised power generation. However, improving their performance requires a detailed understanding of mass-transport processes within gas diffusion layers (GDLs), which …

Optimizing Salt Production by Estimating Brine’s Daily Height From Seawater Evaporation at Djègbadji (Benin Republic)

Armel Vitouley, Guy Hervé Hounguè, Gabin Koto N’Gobi, Julien Adounkpè et autres

Historically, salt production at Djègbadji (Benin Republic) started five to six centuries ago, traditionally relying on labor-intensive methods, consisting on leaching salty soils to obtain brine, a core component in the process. However, salt production could be streamlined by evaporating seawater in …
