      Hydrogen produced from the conversion of hydrocarbons or alcohols contains variable amounts of CO that should be removed for some applications such as feeding low-temperature polymer electrolyte membrane fuel cells (PEMFCs). ...
    • Hydrogen production from water electrolysis: current status and future trends 

      Ursúa Rubio, Alfredo Upna Orcid; Gandía Pascual, Luis Upna Orcid; Sanchis Gúrpide, Pablo Upna Orcid (IEEE, 2012)   Artículo / Artikulua  OpenAccess
      This paper reviews water electrolysis technologies for hydrogen production and also surveys the state of the art of water electrolysis integration with renewable energies. First, attention is paid to the thermodynamic and ...
    • Influence of the power supply on the energy efficiency of an alkaline water electrolyser 

      Ursúa Rubio, Alfredo Upna Orcid; Marroyo Palomo, Luis Upna Orcid; Gubía Villabona, Eugenio Upna Orcid; Gandía Pascual, Luis Upna Orcid; Diéguez Elizondo, Pedro Upna Orcid; Sanchis Gúrpide, Pablo Upna Orcid (Elsevier, 2009)   Artículo / Artikulua  OpenAccess
      Electric energy consumption represents the greatest part of the cost of the hydrogen produced by water electrolysis. An effort is being carried out to reduce this electric consumption and improve the global efficiency ...
    • Kinetic analysis and CFD simulations of the photocatalytic production of hydrogen in silicone microreactors from water-ethanol mixtures 

      Castedo, Alejandra; Uriz Doray, Irantzu Upna Orcid; Soler, Lluís; Gandía Pascual, Luis Upna Orcid; Llorca Piqué, Jordi (Elsevier, 2017)   Artículo / Artikulua  OpenAccess
      Silicone microreactors containing microchannels of 500 μm width in a single or triple stack configuration have been manufactured, coated with an Au/TiO2 photocatalyst and tested for the photocatalytic production of hydrogen ...
    • Outstanding performance of rehydrated Mg-Al hydrotalcites as heterogeneous methanolysis catalysts for the synthesis of biodiesel 

      Navajas León, Alberto Upna Orcid; Campo Aranguren, Idoia; Moral Larrasoaña, Ainara Upna; Echave, Javier; Sanz, Oihane; Montes, Mario; Odriozola, José Antonio; Arzamendi Manterola, María Cruz Upna Orcid; Gandía Pascual, Luis Upna Orcid (Elsevier, 2018)   Artículo / Artikulua  OpenAccess
      There is still a need for active, selective and stable heterogeneous catalysts for the synthesis of biodiesel. In this work, magnesium-aluminium hydrotalcites with Mg/Al molar ratios within the 1.5–5 range were synthesized ...
