Refinement of the calculation of the efficiency of a chemical generator
Abstract
Aim of the article: Analitical calculations and preliminary estimates of efficiency of a chemical generators are of great importance for analysis of conversion chemical energy into electrical one, the base which was consist transformation of heterogeneous chemical energy of formation hydrogen molecules into energy of electronic excitation on the surface of catalyst-semiconductors. However in the works cited by the calculation of probability excitation of chemo-electrons (high-energy electrons in conduction band) is not taken into account of the phonon’s channel of the chemical energy accommodation. Such consideration would be by disdain of interaction excited electron with lattice, but in condition of the scattering chemical reaction energy inevitably was shifted of the equilibrium position of oscillators, leading to emission and absorption of phonons. Therefor the technique of the calculation must take into account as electrons as phonons
channels of the accomodation. Aim of given work is derivation of the theoretical formula for efficiency of chemo-generator with provision for thermo-stimuleted transition of electrons to conduction band, with the subsequent analysis of particular cases.
Theoretical part: The influence of local thermal oscillations of crystal were inducted the effect of chemical reaction energy of formation hydrogen molecules on the “catalyst” surface, on velocity generation of the high-energy electrons was theoretical investigated. The formulas for efficiency of generator, clarifying the corresponding formulas from the other works was obtained. It is indicated on an impotant part of thermo-stimuleted transitions of an electrons to the conduction band of the semiconductor at room temperatures.
Conclusions: The results obtained may be useful by qualitatively analysis of the accommodation mechanisms of a chemical energy in the context of problem of conversion a chemical energy to electrical one
