Mezoporézní nikl-oxid nikelnatý pro katalyzátory palivových článků
Barath, Peter ; Uhlířová, Tereza ; Reiter, Jakub
Nanostructured (mesoporous) nickel-nickel oxide was prepared from the medium of the lyotropic liquid crystals. The electrochemical properties of the material deposited in thin layers were studied, especially the hydrogen oxidation reaction. The catalyst exhibits remarkable catalytic activity.
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.
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.
Ionexové membrány aniontového typu
Vondrák, Jiří ; Sedlaříková, M. ; Barath, P. ; Novák, V. ; Kliment, J.
An anionic ion exchanging membrane was synthetised by a reaction of polyepichlorhydrine and DABCO (diazobicyclooctane) with networking agents. It is not blocked by carbonate ions.
Iontoměničové membrány
Barath, P. ; Novák, V. ; Sedlaříková, M. ; Vondrák, Jiří ; Kazelle, J. ; Kliment, J.
The behaviour of a bipolar ionex membrane FUMATECh was studied in the potential range where the presence of an internal potential bariere inhibits any flow of current.
Počáteční potenciál redukce kyslíku v alkalických palivových článcích
Vondrák, Jiří ; Velická, Jana ; Barath, P. ; Sedlaříková, M. ; Kazelle, J. ; Kliment, J.
The onset potential of oxygen reductin was defined as the potential, below which the electroreduction of oxygen is possible. This value can be used for the comparison of various electrocatalysts. The method was tested on several carbonaceous materials onto which the same amount of platinum was deposited.
