  • Analysis of droplet dynamics on the GDL surface of a PEM fuel cell cathode 

    Jarauta Arabí, Alexandre (Universitat Politècnica de Catalunya, 2013-06-28)
    Master thesis
    Open Access
    A fuel cell is an electrochemical device that has the ability to turn the chemical energy in a fuel directly into electricity with high e ciency. Inside the fuel cell, oxidation and reduction electrochemical reactions ...
  • An embedded approach for immiscible multi-fluid problems 

    Ryzhakov, Pavel; Jarauta Arabí, Alexandre (2015-11-30)
    Article
    Open Access
    An embedded formulation for the simulation of immiscible multi-fluid problems is proposed. The method is particularly designed for handling gas-liquid systems. Gas and liquid are modeled using the Eulerian and the Lagrangian ...
  • A semi-analytical model for droplet dynamics on the GDL surface of a PEFC electrode 

    Jarauta Arabí, Alexandre; Secanell, Marc; Pons Prats, Jordi; Ryzhakov, Pavel; Idelsohn Barg, Sergio Rodolfo; Oñate Ibáñez de Navarra, Eugenio (2015-04)
    Article
    Open Access
    Water management is one of the key factors in Proton Exchange Fuel Cell (PEFC) performance. The water produced within the fuel cell is evacuated through the gas channels, but at high current densities water can block the ...
  • Modeling of droplet dynamics in a proton exchange fuel cell electrode channel 

    Jarauta Arabí, Alexandre (Universitat Politècnica de Catalunya, 2016-03-30)
    Doctoral thesis
    Open Access
    Fuel cells are promising alternatives to conventional energy conversion devices. Cells fueled with hydrogen are environmentally friendly and their effciency is up to 3 times higher than that of high-temperature combustion ...
  • Modelització d’una pila de combustible tipus PEM mitjançant el Mètode dels Elements Finits 

    Jarauta Arabí, Alexandre (Universitat Politècnica de Catalunya, 2010-12)
    Master thesis (pre-Bologna period)
    Open Access
    En aquest Projecte Final de Carrera es pretén modelar matemàticament una pila de combustible per tal de predir el seu comportament mitjançant el Mètode dels Elements Finits. Primerament es fa un estudi de l’estat de l’art ...
