[en] Based on the example of a nanopowder system ZrO₂–3% mol Y₂O₃ with atmospheric humidity interaction, the possibility of exothermic heterophase electrochemical energy conversion to electric energy is shown. Electrical properties and structure of the experimental sample were studied under gradient molecular flux density of humidity during sample saturation. The idea of development of the novel chemo-electronic converter device based on nanoscale dielectrics as ZrO₂–3% mol Y₂O₃ is proposed.

[en] The exothermic heterogeneous electrochemical energy conversion to the electric energy through interaction of the ZrO₂ based nanopowder system with atmospheric moisture have been explored within this work. Electrical properties of the experimental samples were investigated during humidification at the conditions of molecular flux density gradient. The morphological features of the surface cross-section and aggregates of 3 mol% Y₂O₃ doped ZrO₂ nanopowder systems were investigated. Initial conditions for molecular dynamics modelling of the adsorption processes were obtained. A novel approach for developing of chemo-electronic converters based on nanoscale processes and materials with dielectric conductivity type proposed. (paper)
