Příspěvek má informativní charakter, vychází z teze, že výchova je významný společenský jev. Výchovně-vzdělávací instituce v České republice se dostávají do těžkostí se záměrným řešením výchovy, tj. s rozvíjením a fo

The electrochemical impedance of a model hermetic lead accumulator and its electrodes was measured during continuous or interrupted charging either in potentiostatic (at 10 4 -10 −3 Hz) or in galvanostatic (at 0.1 Hz) mode. The impedance characteri

The impedance characteristics of different hermetic NiCd accumulators were studied in the frequency range 10 −2 –10 3 Hz during standing after charging to a pressure of 150 kPa. The pressure decreased linearly over several hours owing to oxyge

Based on barodynamic characteristics, both the oxygen pressure and the oxygen reduction current at the negative electrode in a sealed lead/acid cell were followed. These data together with potentiodynamic characteristics were used to characterize the

The use of plastic-bonded (PB) electrodes in prismatic, sealed NiCd cells is limited by the need for a negative electrode layer (active material, plastic binder, activating agents) with the highest possible oxygen recombination rate. Otherwise, a

The second discharge step of nickel oxide accumulator electrodes is suppressed in the presence of a Teflon binder and/or cobalt, cerium, or manganese hydroxide, whereas the first discharge step increases. This behaviour is discussed in terms of ohmic

The electrochemical parameters of carbon—oxygen gas-diffusion electrodes can be controlled over a wide range by varying the structure of the active carbon catalyst and the ratio of lyophilic and lyophobic pores in the catalyst particles. Two typica
