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.
Protonově vodivé polymerní elektrolyty na bázi methakrylátů
Reiter, Jakub ; Velická, Jana ; Míka, M.
New, proton conductive electrolytes based on methacrylates and phosphoric acid were prepared. These aprotic electrolytes exhibit conductivity up to 0.1 mS/cm and they were also characterised using voltammetrical and thermogravimetrical methods.
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.
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.
Pevné a polymerní elektrolyty pro elektrochemické sensory plynů
Vondrák, Jiří ; Reiter, Jakub ; Mašínová, M. ; Paidar, M. ; Míka, M. ; Bouzek, K.
Polymer gel and hybride inorganic-organic membranes were used for the construction of chemical sensors for hydrogen fluoride and hydrogen.
Protonově vodivé fosfokřemičitanové membrány
Mika, J. ; Masinová, M. ; Švarcová, S. ; Paidar, M. ; Bouzek, K. ; Klápště, Břetislav ; Vondrák, Jiří
Hybride inorganic-organic membranes with high proton conductivity were prepared and studied. These membranes were used as solid electrolytes in hydrogen chemical sensor and in the model fuel cell.
