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.
Elastické organicko – anorganické membrány s protonovou vodivostí
Míka, M. ; Mašínová, M. ; Švarcová, S. ; Paidar, M. ; Bouzek, K. ; Klápště, Břetislav ; Vondrák, Jiří
A polymeric electrolyte was synthetised and its properties were tested in a laboratory hydrogen – oxygen fuel cell at moderately increased temperature. The poymer is based on organosilicates modified by phosphoric acid.
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.
