The performance of an open cathode fuel cell was investigated as a function the type gas diffusion layer used in its membrane electrode assemble (MEA) preparation. In this context, new developed our laboratory called eCoCell studied, comparison with reputed commercial one Sigracet 38BC. Thus, characterization both layers carried out through measurement following properties: porosity, electrical conductivity, thermal conductivity and hydrophobicity. Finally, single proton exchange using...
Abstract The gas diffusion layer (GDL) is one of the most important parts a proton exchange membrane fuel cell, that plays key role transporting current to collector plates, distributing reactant gases catalyst surface, and evacuating heat water generated during redox reactions inside cell. Speaking in terms production cost, GDL represents up 45% total cost electrode assembling (MEA). However, despite its crucial until recent years, GDLs have not been studied with same intensity as other MEA...
Hydrogen production through electrolysis using renewable resources is highly promising for reducing greenhouse gas emissions. While significant efforts have focused on developing more efficient and cost-effective catalysts to lower hydrogen costs, are not the primary expense in electrolyzer fabrication. In case of Proton Exchange Membrane Water Electrolyzers (PEMWEs), other components—such as proton membrane, diffusion layer (GDL), bipolar plates—contribute overall costs. To explore this, a...
Fabrication of electrodes for polymer electrolyte fuel cells is a intriguing process in which balance between gas transport, electrical conductivity, proton transport and water managing must be optimized. In this work four different prepared by electrospray deposition have been studied using catalytic inks, Nafion epoxy doped with Graphene-Nanoplatelets were used as binders. After studying the behavior those single open cathode cell membrane, it clear that addition binder graphene, improves...
Lithium metal anodes are indispensable for next-generation batteries including Lithium-Sulfur and Lithium-air which show high promise electric vehicles other energy storage applications. Challenges such as extreme reactivity lithium dendrite formation have kept away from practical on anode surfaces during the charging process originates inhomogeneous deposition of metallic electrochemical reduction cations. However, underlying mechanisms Li ion electrolyte solution onto surface still poorly...
Cation transport through the electrolyte to anode is one most important steps understand desolvation and diffusion phase To help understanding this step, there a sustained development of sophisticated in situ surface science electrochemical techniques, first-principles based computational methods. In work, we analyze structure dynamics state-of-the-art electrolytes particularly at interfaces typical intercalation anodes. We use classical reactive molecular ab initio characterize interfacial...
Lithium metal anode is considered a great candidate because of its high theoretical capacity and negative electrochemical potential. However, key factors like poor cyclability as well the safety issues related to uneven lithium electrodeposition, dendrite growth, unstable solid electrolyte interphase (SEI) are keeping batteries away from commercialization. Different attempts both experimentally theoretically have been done decode exact structure distribution SEI, but due inherent dynamic...
