PANDEY, Kamlesh; DWIVEDI, Mrigank M.  e  TRIPATHI, Mridula. Study of Dehydrated Salts: Electrolyte for Intermediate Temperature Fuel Cell. Port. Electrochim. Acta [online]. 2009, vol.27, n.2, pp.99-111. ISSN 0872-1904.

Fuel cells are receiving growing interest in recent years since they represent one of the most promising energy source to reduce pollutant emission. We propose some new dehydrated salts as an electrolyte in the intermediate temperature fuel cell. The proton conduction in the dehydrated salts was established by the study of DTA/TGA, infrared spectroscopic study, transference number, bulk electrical conductivity measurement and emf study. The electrical conductivity of the dehydrated salts becomes ionic and increases 100-1000 times in the hydrogen ambient with respect to vacuum.

Palavras-chave : hydrogen-oxygen; fuel cell; proton conductor; dehydrated salt; electrochemical emf.
