FIELD: electricity. ^ SUBSTANCE: invention relates to design of efficient chemical current sources which provide direct conversion of a redox reaction to electrical energy, bypassing the inefficient (accompanied with large losses) burning process. According to the invention, a "jacket" is worn on a widely used fuel cell (FC) of tubular topology, in which a redox reaction is converted to electrical energy, where the jacket is in form of a three-layer split pipe structure, where the inner and the outer layers are current contacts, and the middle layer is a semiconductor structure based on samaric sulphide (SmS). The said "jacket" is a thermoelectric converter (TEC) which can generate emf when heated uniformly. That way, under the effect of excess heat released by the fuel cell, an intrinsic emf arises in the thermoelectric converter, which is summed with the emf of the fuel cell. ^ EFFECT: increase in efficiency (efficiency of generation of electrical energy) of the combined system by over 20%. ^ 2 cl, 3 dwg |
