Water management is one issue that must be surpassed to ensure high membrane proton conductivity and adequate reactant transport in the membrane-electrode assembly (MEA) simultaneously. A well-designed water system based on a comprehensive understanding of inner part polymer electrolyte (PEM) fuel cell. In this work, phenomena MEA PEM cell are analyzed by using mathematical model. The diluted s...

The formation of discrete water clusters in polymer electrolyte fuel cell gas diffusion layers (GDL) can lead to increased resistance for oxygen transport the catalyst layer. This study investigates effect MPL crack propagation on cluster development a X-ray computed tomography (CT) microstructure using volume-of-fluid method (VoF). VoF calculation was compared operando CT data by voxel matchin...

A proton exchange membrane fuel cell is an energy convertor that produces environmentally friendly electrical by oxidation of hydrogen, with water and heat being byproducts. This study investigates the gas diffusion layer (GDL) electrode assembly (MEA) in cells (PEMFCs). In this regard, key design concerns restraints GDL have been assessed, accompanied inclusive evaluation presently existing mo...

Proton exchange membrane fuel cell (PEM-FC) aggregation pressure causes extensive strains in segments. The compression of each segment takes place through the modeling method. In addition, a very heterogeneous compressive load is produced because recurrent channel rib design dipole plates, so that while high are provided below rib, domain continues its initial uncompressed case under ducts appr...

Abstract A three-dimensional multicomponent multiphase lattice Boltzmann model (LBM) is established to the coupled two-phase and reactive transport phenomena in cathode electrode of proton exchange membrane fuel cells. The gas diffusion layer (GDL) microporous (MPL) are stochastically reconstructed with inside dynamic distribution oxygen liquid water resolved, catalyst simplified as a superthin...

Se presenta el diseño mecánico y electrónico, modelado cinemático dinámico, programación control de un helicóptero 2 GDL bajo costo. Si bien existen plataformas comerciales helicópteros GDL, su costo es elevado por ende son poco accesibles. Esta situación puede evitarse mediante uso una plataforma basada en software código abierto sistema adquisición datos Para este fin, artículo se cuyos movim...

The production of gamma-decalactone (GDL) by Yarrowia lipolytica is mainly based on the biotransformation ricinoleic acid, derived from castor oil triglycerides. main difficulty in this process multitude factors that determine growth rate microorganisms, and thus affect efficiency lactone synthesis. In order to improve technological aspects GDL biosynthesis batch culture, influence three was de...

In this paper we focus on solving DCOPs in computationally demanding scenarios. GDL optimally solves DCOPs, but requires exponentially large cost functions, being impractical in such settings. Function filtering is a technique that reduces the size of cost functions. We improve the effectiveness of function filtering to reduce the amount of resources required to optimally solve DCOPs. As a resu...
