Elastic proton conducting inorganic-organic electrolytes
Míka, M.; Mašínová, M.; Švarcová, S.; Paidar, M.; Bouzek, K.; Klápště, Břetislav; Vondrák, Jiří
2006 - English
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. Byl synthetisován polymerní elektrolyt na bázi organokřemičitých sloučenin modifikovaných kyselinou fosforečnou. Materiál, vyznačující se protonovou vodivostí, byl testován v laboratorním palivovém článku při mírně zvýšených teplotách.

Antionic ionex membranes
Vondrák, Jiří; Sedlaříková, M.; Barath, P.; Novák, V.; Kliment, J.
2006 - English
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. Reakcí polyepichlorhydrinu a DABCO (diazobicyklooktanu) se síťovacími činidly byl připraven iontoměnič anexového typu a byla z něho vytvořena membrána pro palivový článek, vyztužená polypropylenovou sítí. Membrána je odolná proti zablokování karbonátovými ionty.

The electrochemical redox processes in the lyotropic liquid crystals,
Uhlířová, T.; Reiter, Jakub; Owen, J.R.
2006 - English
Electrochemical behaviour of ferrocene was studied in the medium of lyotropic liquid crystals, which serve as a matrix for the preparation of nanostructured compounds (metals and oxides). Diffusion coefficient and half-wave potential of ferrocene was determined. Bylo studováno elektrochemické chování ferrocenu v prostředí lyotropních kapalných krystalů, které slouží jako matrice pro přípravu nanostrukturních látek (kovů a oxidů). Byl stanoven difúzní koeficient ferrocenu a jeho půlvlnový potenciál.
