Proton Exchange Membrane Fuel Cells (PEMFCs): Advances and Challenges

Tellez-Cruz, Miriam M.; Escorihuela, Jorge; Solorza-Feria, Omar; Compañ Moreno, Vicente (MDPI AG, 2021-09)

[EN] The study of the electrochemical catalyst conversion of renewable electricity and carbon oxides into chemical fuels attracts a great deal of attention by different researchers. The main role of this process is in ...
Protonic Conduction of Partially-Substituted CsH2PO4 and the Applicability in Electrochemical Devices

Navarrete Algaba, Laura; Andrio, Andreu; Escolástico Rozalén, Sonia; Moya, Sergio; Compañ Moreno, Vicente; Serra Alfaro, José Manuel (MDPI AG, 2019-04)

[EN] CsH2PO4 is a proton conductor pertaining to the acid salts group and shows a phase transition from monoclinic to cubic phase at 232 +/- 2 degrees C under high-steam atmospheres (>30%). This cubic phase gives rise to ...
Quaternary mixture designs applied to the development of multi-element oxygen electrocatalysts based on the Ln(0.58)Sr(0.4)Fe(0.8)Co(0.2)O(3-delta) system (Ln = La1-x-y-zPrxSmyBaz): Predictive modeling approaches

Serra Alfaro, José Manuel; Vert Belenguer, Vicente Bernardo (Elsevier, 2011-01-10)

[EN] The experimental data generated through the optimization of oxygen electrocatalysts based on the perovskite Ln(0.58)Sr(0.4)Fe(0.8)Co(0.2)O(3-delta) system (Ln = La1-x-y-zPrxSmyBaz) have been modeled following different ...
Reversible electrodes based on B-site substituted Ba0.5Sr0.5Co0.8Fe0.2O3-delta for intermediate temperature solid-oxide cells

Navarrete Algaba, Laura; Hannahan, C.; Serra Alfaro, José Manuel (Elsevier, 2022-03)

[EN] The Ba0.5Sr0.5Co0.8Fe0.2O3-delta perovskite is a promising electrode material for solid-oxide electrochemical cells exhibiting excellent oxygen reduction reaction (ORR) activity and mixed ionic-electronic transport ...
Study of the transport properties of the mixed ionic electronic conductor Ce 1-x Tb x O 2- + Co (x=0.1, 0.2) and evaluation as oxygen-transport membrane

Balaguer Ramírez, María; Solis Díaz, Cecilia; Serra Alfaro, José Manuel (American Chemical Society, 2011)

[EN] Tb-doped ceria materials have been synthesized by the coprecipitation method. Cobalt oxide (2 mol %) has been added in order to improve the sinterability and conductivity. XRD measurements suggest that a part of the ...
TECHNICAL REQUIREMENTS FOR ECONOMICAL VIABILITY OF ELECTRICITY GENERATION IN STABILIZED WIND PARKS

Segura Heras, Isidoro; Pérez-Navarro Gómez, Ángel; Sánchez Díaz, Carlos; Ibañez Escobar, Fernando; Payá Herrero, Jorge; Bernal Serra, Eva (Elsevier, 2007-11)

Wind generation is substantially increasing its share in the electricity generation portfolio in many countries. In the case of Spain, it can more than double in the next 4 years, reaching a 20GW level. To become competitive ...
