Byly sestrojeny hybridní elektrochromní prvky s různými elektrolyty a studovány jeho optické a elektrochemické vlastnosti
Krejza, O. ; Reiter, Jakub
Hybride electrochromic devices were assembled with different electrolytes and their optical and electrochemical properties were studied.
Elektrochemická aktivity elektrokatalyzátorů na bázi oxidů manganu a uhlíku
Vondrák, Jiří ; Klápště, Břetislav ; Velická, Jana ; Sedlaříková, M. ; Roche, I. ; Chainet, E. ; Chatenet, M.
New catalysts based on doped manganese oxides for oxygen reduction in fuel cells were prepared. Oxygen reduction reaction in alkaline medium was studied and the catalytical activity of the new material is comparable to the activity of platinum.
Polymerní gelové elektrolyty na bázi poly(ethylmethakrylátu) and poly(2-ethoxymethyl methakrylátu)
Reiter, Jakub ; Michálek, Jiří ; Vondrák, Jiří ; Chmelíková, Dana ; Přádný, Martin
New methacrylate-based polymer electrolytes were prepared using UV initiated radical polymerization. Prepared composites were characterized using voltammetrical and impedance methods and their composition was optimized.

Kocián, M. ; Štěpánek, M. ; Vondrák, Jiří ; Sedlaříková, M.
Polymer gel and hybride inorganic-organic membranes were used for the construction of chemical sensors for hydrogen fluoride and hydrogen.
Tenké vrstvy pro elektrochromní zařízení
Macalík, M. ; Vondrák, Jiří ; Sedlaříková, M. ; Mohelníková, J. ; Helán, R.
Thin-layer transparent electrodes of tungsten or vanadium oxide were prepared and tested in electrochromic devices.
Průhledné elektrody na bázi naprašovaného oxidu cíničitého
Macalík, M. ; Vondrák, Jiří ; Koten, S. ; Maršík, P.
Thin-layer transparent electrodes of doped tin (IV) oxide were prepared and tested in electrochromic devices.
Katalyzátory pro palivové články
Bílek, J. ; Dokoupil, A. ; Vognar, J. ; Vondrák, Jiří ; Novák, V.
