SYSTEM OF FUEL ELEMENTS

FIELD: heating; electricity. ^ SUBSTANCE: according to invention the system of fuel elements contains the following: fuel element on the basis of direct conversion of borohydride for generation of energy during fuel reception; fuel element with proton-exchange membrane for generation of energy during hydrogen reception, as side product generated on anode of fuel element on the basis of direct conversion of borohydride after reaction, in the capacity of fuel; auxiliary energy source, which is partially charged with energy generated by fuel element on the basis of direct conversion of borohydride and fuel element with proton-exchange membrane, and discharging charged energy; load sensor for reading of load connected with fuel element on the basis of direct conversion of borohydride, fuel element with proton-exchnage membrane and auxiliary source of energy; and control unit for regulation of fuel element capacity on the basis of direct conversion of borohydride, fuel element with proton-exchange membrane and auxiliary energy source in accordance with load, which is read by load sensor, and thereby for selective feeding of load. In accordance with that hydrogen produced by fuel element on the basis of direct conversion of borohydride recirculates, and load value is read. ^ EFFECT: maximisation of fuel use efficiency and stable control of the system. ^ 17 cl, 7 dwg
