    • Distributed parameter model-based control of water activity and concentration of reactants in a polymer electrolyte membrane fuel cell 

      Sarmiento Carnevali, María Laura; Serra, Maria; Batlle Arnau, Carles (2017-01-01)
      Article
      Accés restringit per política de l'editorial
      Water management is still a key challenge for optimal performance and durability of polymer electrolyte membrane (PEM) fuel cells. Water levels along the channel in a PEM fuel cell present important spatial variations that ...

    • Distributed parameter PEMFC model order reduction 

      Sarmiento Carnevali, María Laura; Batlle Arnau, Carles; Serra, Maria; Massana Hugas, Immaculada (2014)
      Comunicació de congrés
      Accés obert
      This work focuses on obtaining an order-reduced model from a nonlinear single PEMFC model, which incorporates the effects of distributed parameters that are relevant for its proper functioning and performance. The original ...

    • Modeling and control of PEM fuel cells 

      Sarmiento Carnevali, María Laura (Universitat Politècnica de Catalunya, 2017-09-22)
      Tesi
      Accés obert
      In recent years, the PEM fuel cell technology has been incorporated to the R&D plans of many key companies in the automotive, stationary power and portable electronics sectors. However, despite current developments, the ...
