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 ...
Influence of Pectin as a green polymer electrolyte on the transport properties of Chitosan-Pectin membranes

Pasini Cabello. S.D.; Ochoa, N.A.; Takara, E.A.; Mollá, S.; Compañ Moreno, Vicente (Elsevier, 2017)

[EN] Novel blend membranes have been prepared from Chitosan (CH), Pectin (PEC) and their mixtures. The obtained samples were cross-linked and sulfonated before characterization. The results show that CH/PEC membranes display ...
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 ...
Polymer blends of SPEEK for DMFC application at intermediate temperatures

Mollá Romano, Sergio; Compañ Moreno, Vicente (Elsevier, 2014-03-26)

[EN] Sulfonated poly(ether–ether–ketone) materials (SPEEK) are good proton conductors at high degrees of sulfonation and appropriate for high temperature application due to their glass transition temperatures around 200 ...
