Facile and green assembly of nanocomposite membranes for fuel cellsElectronic supplementary information (ESI) available. See DOI: 10.1039/c4cc08347d

We report on a facile spray deposition method, which allows obtaining nanocomposite membranes for high-temperature polymer fuel cells characterized by high homogeneity and excellent proton conductivity. The proposed method is also green, as it requires much smaller amounts of solvents with respect to standard casting. Spray deposition is a facile and green method to obtain nanocomposite membranes for HT-PEMFCs characterized by high homogeneity and excellent proton conductivity.
