	Stabilita alpha-Ni(OH)2 v závislosti na koncentraci elektrolytu Vrbický, J. ; Vondrák, Jiří ; Sedlaříková, M. Alpha nickel hydroxide is stable in normal conditions, but in alkaline electrolytes is unstable. Detailed record
	HOR NiOx jako elektrokatalyzátor palivových článků H2-O2 Barath, P. ; Sedlaříková, M. ; Vondrák, Jiří ; Chatenet, M. ; Roche, I. Ni Ni/C and Raney Ni materials were studied as electrocatalysts for the HOR in alkaline medium. Detailed record
	Fosfosilikátové membrány jako t. prostředek vodíkových palivových článků Míka, M. ; Klápště, Břetislav ; Michal, J. ; Vondrák, Jiří Increasing consumption of electric energy and its rising cost initiated an search for new technologies that can produce the energy more effectively and environment friendly. Detailed record
	Kinetické vlastnosti kladných elektrod se základem MnO2 s různými dopujícími přísadami Vognar, J. ; Brudná, S. ; Novák, V. ; Vondrák, Jiří ; Sedlaříková, M. The present study aims at evaluating the activity of such manganise oxide-based electrocatalysts toward the ORR. Electrochemical measurement was realized by method of cyclic voltametry on RDE in three electrodes circuit. Detailed record
	Katalyzátory kladných elektrod palivových článků Novák, V. ; Brudná, S. ; Vognar, J. ; Barath, P. ; Vondrák, Jiří ; Sedlaříková, M. ; Kazelle, J. The fuel cells belongs to group of derivaces in which is internal energy of the fuel changed into the electrical energy.The electrochemical reaction is representanted by marked peak in half wave potential area.By that method can be found out activity of the electrode which determine potential of inflection point or potential of half-wave. Detailed record
	Vliv substrátu SnO2 na elektrochromní vlastnosti WO3 Macalík, M. ; Vondrák, Jiří ; Sedlaříková, M. ; Mohleníková, J. The use of SnO2 electrically conductive layers prepared either by vacuum deposition or by spray pyrolysis was tested as support for electrochromic layers WO3. Vacuum deposited electrode exhibited better transparency, while the performance of chemically deposited electrodes was quite sufficient. Detailed record
	Přídavky manganu a niklu do elektrodových materiálů lithno-iontových baterií Jirák, T. ; Vondrák, Jiří ; Sedlaříková, M. ; Hejátková, E. The properties of electrode material based on LiCoO2 were modified by substitution of cobalt by Ni and/or Mn compounds. Specific energy of new material was lower, but their lifetime (number of cycles) was improved. Detailed record
	MnO2 studovaný metodou EQCM Špičák, P. ; Svoboda, V. ; Sedlaříková, M. ; Vondrák, Jiří ; Kazelle, J. Mass changes of electrodes containing MnO2 during charging and discharging processes were studied using QCMB techniques. The process is accompanied by reversible uptake of water and insertion of H3O+ insted of H+ should be expected. Detailed record
	Nanotrubice jako příměs do kladné elektrody Li-iontové baterie Sysel, M. ; Makovička, J. ; Sedlaříková, M. ; Vondrák, Jiří Active mass for positive electrode of Li-ion batteries should be improved by carbon particles for enhancement of electrical conductivity. Carbon nanotubes were tested for this purpose. Detailed record
	Grafitové elektrody pro Li-iontové baterie Makovička, J. ; Sedlaříková, M. ; Vondrák, Jiří The results illustrate that the expanded graphote is a promising candidate for Li-ion batteries but irreversible capacity in the cycle has to be decreased. Detailed record
