  • Effect of water content in the gas diffusion layer of H2 O2 PEM fuel cell 

    Cespedes, German; Asteazaran, Mariano; Castro Luna, Ana (Journal of Materials Science and Engineering, 2016)
    The heart of a fuel cell is the membrane-electrode assembly consisting of two porous electrodes, where the electrochemical reactions take place, and the ionomer conductive membrane, which allows the proton exchange from ...

  • Estudio de catalizadores para el cátodo de una celda de combustible de metanol directo 

    Asteazaran, Mariano; Castro Luna, Ana (Investigación Joven, 2014)
    Las celdas de combustible de metanol directo, DMFCs, convierten la energía química almacenada en el metanol en energía eléctrica de forma eficiente y con bajo impacto medioambiental. Las DMFCs tienen como ventajas que el ...
