	Uhlíkové nanotrubice v superkondenzátorech Kocian, Martin ; Vondrák, Jiří ; Sedlaříková, M. The electrodes suitable for supercapacitors were prepared from carbon nanotubes (Aldrich) and PTFE binder. Specific capacites of the order 10 F/g were achieved. Detailed record
	Elektrolyty pro elektrochemické superkondenzátory Přikryl, M. ; Kocian, Martin ; Sedlaříková, M. ; Vondrák, Jiří ; Hajátková, E. ; Mohelníková, J. These components have wide applications in the presents industrial world because of their properties. Detailed record
	Dvojvrstva na uhlíku v aprotických elektrolytech Vondrák, Jiří ; Sedlaříková, M. ; Velická, Jana ; Kocian, Martin ; Špachman, V. ; Klápště, Břetislav As carbonaceous materials we started with glassy carbon electrodes and continued to use variety pf carbon black powders, carbon nanotubes and chemically modified graphite in powderized form. Detailed record
	Charakterizace protonově vodivých fosfosilikátových membrán pro palivové články H2/O2 Míka, M. ; Mašínová, M. ; Švarcová, S. ; Paidar, M. ; Bouzek, K. ; Klápště, Břetislav ; Vondrák, Jiří We tested the performance of our membranes in a H2/O2 fuel cell using standard E-TEK electrodes Pt/C under low humidity conditions where the reactant gas streams were not humidified. Detailed record
	Příprava a vlastnosti elektrod V2O5 pro elektrochromní součástky Macalík, M. ; Matěj, A. ; Sedlaříková, M. ; Vondrák, Jiří The preparation of SnO2 based layers by spray method seems interesting for the technology as no vacuum is necessary for it. Vanadium oxide films were dip-coated on FTO layers. Detailed record
	Vlastnosti gelových elektrolytů na bázi NaClO4 a PMMA Nováček, T. ; Vondrák, Jiří ; Sedlaříková, M. ; Šiková, P. For applications of polymer gel electrolytes it is necessary to know his electrical parameters, for instance the specific conductivity. Detailed record
	Materiál na základě LiCoO2 dopovaného alkalickými kovy pro positivní elektrody sekundárních lithiových baterií Jirák, T. ; Sedlaříková, M. ; Vondrák, Jiří ; Makovička, J. ; Polsterová, H. Obtained results allow the application of prepared materials in modern chemical power sources. The quaternary systems containing lithium salts will be studied as solid electrolytes in lithium-ion batteries and the ternary systems will be combined with carbon powders of high surface area to form supercapacitors. Detailed record
	Redukce kyslíku v elektrolytu obsahujícím hydroxid a borohydrid sodný Chatenet, M. ; Micoud, F. ; Roche, I. ; Chainet, E. ; Vondrák, Jiří The Principle of double layer on carbon electrode has been used for the design of new components, called electrochemical supercapatitors. Detailed record
	Elektrokatalyzátory na bázi oxidů manganu a uhlíku pro reakci ORR v alkalickém prostředí Roche, I. ; Chainet, E. ; Chatenet, M. ; Vondrák, Jiří The aim of the present paper is to elucidate, in complement of the activity evalution, the ORR mechanism on these electrocatalysts in alkaline medium. Detailed record
	Elektrody pro elektrochromní zařízení studované pomocí EQCM Špičák, P. ; Svoboda, V. ; Sedlaříková, M. ; Vondrák, Jiří ; Kazelle, J. The crystal surface with the layer is exposed to the electrolyte in a three-electrode systems, usuallydriven by potentiostat. This frequency change is used for detection ofchemical changes of the electrode surface.This system is very sensitive. Detailed record
