Characterisation of fuel cell state using Electrochemical Impedance Spectroscopy analysis
(EHU, 2008)
Text en actes de congrés
Accés obertOne of the most demanding research topics related to the Polymer Electrolyte Membrane Fuel Cell (PEMFC) concerns its reliability. Apart from the security aspects, it is basic to have a diagnosis of the internal state of ... -
Experimental analysis of a degraded open-cathode PEM fuel cell stack
(2013)
Text en actes de congrés
Accés obertThe well-known challenges to be overcome in PEM fuel cell research are their relatively low durability and high costs for the platinum catalysts. Thus, this work focuses on factors that impact durability and the links to ... -
Experimental study of hydrogen purge effects on performance and efficiency of an open-cathode proton exchange membrane fuel cell system
(2013)
Article
Accés obertThe performance and efficiency of an open-cathode PEM fuel cell system in dead-ended anode (DEA) configuration and hydrogen purges is analyzed in this work. Excess water and crossed-over nitrogen in the anode decrease the ... -
Novel epoxy coating based on DMSO as a green solvent, reducing drastically the volatile organic compound content and using conducting polymers as a nontoxic anticorrosive pigment
(American Chemical Society (ACS), 2013-12-02)
Article
Accés restringit per política de l'editorialThis work reports novel anticorrosive epoxy coatings based on safer dimethyl sulfoxide solvent and free of zinc anticorrosive pigment. The latter was replaced by conducting polymers, as nontoxic anticorrosive pigments. ... -
