	Materials for positive electrodes of fuel cells Novák, V. ; Brudná, S. ; Barath, P. ; Vondrák, Jiří ; Sedlaříková, M. New development in non-platinum electrocatalysts for oxygen electrode in alkaline fuel cell. 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
	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
	Alkalické iontově výměnné membrány ve zdrojích proudu Barath, P. ; Janík, L. ; Sedlaříková, M. ; Vondrák, Jiří ; Novák, V. ; Reiter, Jakub Bipolar membranes for alkaline fuel cells were prepared and studied. Detailed record
	Integration of Biomass Gasification with High Temperature Fuel Cells Svoboda, Karel ; Hartman, Miloslav ; Baxter, D. ; Hunter, Ch. This contribution gives information about possibilities of efficient production of fuel gas for high temperature fuel cells (SOFC or MCFC) by biomass gasification, esp. in fluidized beds, about efficient fuel gas cleaning, requirements and practical limits of fuel gas purity and effects of basic operating parameters on the efficiency of fuel gas production. The overall efficiency of power production based on biomass gasification with steam cycle, combined cycle and cycles exploiting high temperature fuel cells is estimated. Detailed record
	Bifunctional Electrode for Fuel Cells Novák, V. ; Vondrák, Jiří We were prepared five samples of electrocatalyst by a chemical reaction of the potassium permanganate and the carbon black. These samples were doped, except for one, by the salts of divalent Mn, Mg, Ni and Zn metals. Detailed record
	Hydrogen/Oxygen Fuel Cells Vondrák, Jiří ; Sedlaříková, M. ; Černý, R. ; Klápště, Břetislav The electrochemical low temperature fuel cells have appeared in the focus of interest recently in many institutions. e have studied the properties of various catalysts and electrolytes with the aim to do a screening of possible replacements of platinum catalysts and exchanging membranes. Detailed record
	Oxygen Gas Electrode for Fuel Cells Závodský, R. ; Dočkal, M. ; Sedlaříková, M. ; Vondrák, Jiří The catalytic electrode composites based on manganese oxide, carbon and binder were tested in this work. The aim of this work was to optimize the amount of polymeric binder and to test the performance of the positive electrode in a model fuel cell containing KOH as the electrolyte. Detailed record
	Electrocatalysts for Fuel Cells Vondrák, Jiří ; Reiter, Jakub ; Velická, Jana ; Klápště, Břetislav Detailed record
	Elektrodové materiály pro vodíko-kyslíkové palivové články Dvořák, J. ; Sedlaříková, M. ; Vondrák, Jiří MnOx/C materials were prepared and their electrocatalytic properties were studied. Detailed record
