Abstract:
Now promptly electricity consumption grows, and traditional ways of electricity generation as electromechanical converters do not give sufficient autonomy and productivity. Therefore, there is sharp need for autonomous alternative energy sources. One of the perspective directions are solid oxide fuel cells (TOTE) in which energy of fuel as a result of chemical reaction passes into electric. In comparison with normal electromechanical converters, they show much higher efficiency which reaches 75%. At the same time TOTE provide noiselessness of work, environmental friendliness due to lack of atmospheric emissions, long-term stability and reliability, and also opportunity to make power stations of very high range of power due to use of the same elements. TOTE are already used in many areas now: in transport, in particular in electric vehicles on hydrogen fuel; in working camps when in the remote human settlements one installation provides with electricity the whole working camp, plant capacity can reach 10 000 kW an hour; in portable sources of current; in municipal services; in the cathode protection on the gas pipeline. Solid electrolyte are TOTE basis therefore efficiency of its work in many respects depends on characteristics of solid electrolyte. In this work physical and chemical patterns of synthesis of powders on the basis of ZrO2 with the complex stabilizing additive from the yttrium oxides and scandium having the properties necessary for agglomeration and creation of dense structure of solid electrolyte and obtaining high values of ionic conduction are considered. Comparative analysis of the initial powders received by three different ways of chemical precipitation is carried out. Ionic conduction of solid electrolyte depending on way of receiving and structure of starting material is investigated. Influence of way of chemical precipitation and the entered stabilizing additives on final properties of solid electrolyte is experimentally shown.
