Application of Nanofibres in Polymer Composite Membranes for Direct Methanol Fuel Cells

Mollá Romano, Sergio (Universitat Politècnica de València, 2015-12-09)

[EN] Direct methanol fuel cells are feasible devices for efficient electrochemical power generation if some issues can be solved regarding both electrodes and membranes. The research carried out in this Ph.D. thesis has ...
Bimetallic electrocatalysts (Pt-M) supported on single-wall carbon nanotubes for hydrogen and methanol electrooxidation in fuel cells

Maya-Cornejo, J.; Garcia-Bernabe, Abel; Compañ Moreno, Vicente (Elsevier, 2018-01-11)

[EN] A series of Pt-Ru and Pt-Mo bimetallic catalysts were prepared via a chemical reduction method by bubbling CO to form carbonyl compounds as metal precursors. In both cases the Pt-Ru and Pt-Mo bimetallic electrocatalysts ...
Modification of Nafion Membranes with Polyaniline to Reduce Methanol Permeability

Gonzalez-Ausejo, J.; Cabedo Mas, Luis; Gámez-Pérez, J.; Mollá Romano, Sergio; Giménez Torres, Enrique; Compañ Moreno, Vicente (Electrochemical Society, 2015)

The modification of Nafion membranes with polyaniline (PAni) has been studied as an alternative for reducing methanol crossover in direct methanol fuel cells (DMFC). The modification has been performed by directly polymerizing ...
New bio-polymeric membranes composed of alginate-carrageenan to be applied as polymer electrolyte membranes for DMFC

Pasini Cabello, S.D.; Mollá Romano, Sergio; Ochoa, N.A.; Marchese, J.; Giménez Torres, Enrique; Compañ Moreno, Vicente (Elsevier, 2014-11-01)

Novel polyelectrolyte membranes were prepared from pure solutions of alginate (Alg), carrageenan (Car) and their mixtures. The films were crosslinked and sulfonated and then, characterized by several techniques: ionic ...
On the methanol permeability through pristine Nafion and Nafion/PVA membranas measured by different techniques. A comparison of methodologies

Mollá Romano, Sergio; Compañ Moreno, Vicente; Lafuente, S.L.; Prats, Joan (Wiley-VCH Verlag, 2011-10-05)

[EN] Methanol crossover through polymer electrolyte membranes is a critical issue and causes an important reduction of per- formance in direct methanol fuel cells (DMFCs). Measuring the evolution of CO 2 gas in the ...
Performance of composite Nafion/PVA membranes for direct methanol fuel cells

Mollá Romano, Sergio; Compañ Moreno, Vicente (Elsevier, 2011-03-01)

This work has been focused on the characterization of the methanol permeability and fuel cell performance of composite Nafion/PVA membranes in function of their thickness, which ranged from 19 to 97 mu m. The composite ...
Water vapour absorption in new liquid crystalline membranes with sulfonic groups for DMFC

Teruel Juanes, Roberto (Universitat Politècnica de València, 2016-02-16)

Direct Methanol and Ethanol Fuel Cells (DMFC and DEFC, respectively) are interesting alternatives for conventional energy conversion systems, allowing for the use of bio-fuels and other renewable energy sources. Despite ...
