At present, the production of electricity for agricultural consumersremote from the centralized electrical power grid is carried out using diesel-generator technology with a limited service life of engines and extremely low efficiency of the expensive fuel used. In this chapter, an innovative technology has been considered for the combined electrical and heat power production using the preliminary conversion of diesel fuel into synthesis gas with its subsequent supply to a high temperature electrochemical generator (ECG). Synthesis gas for the operation of the electrochemical generator was produced by air conversion of motor diesel fuels in a catalytic burner reactor. On the basis of heat balances of the burner, ECG and waste-heat boiler-utilizer, electrical efficiency of the solid oxide fuel cells' (SOFC) battery, chemical efficiency of the burner, the temperature at the SOFC anode, the EMF of the planar cell, a portion of hydrogen oxidized at the SOFC anode,specific consumption of diesel fuel for the production of electrical and heat power were calculated.
