FIELD: electricity, heating.
SUBSTANCE: according to invention by-product in fuel-element aggregate in the form of water and water steam is supplied to water coolant loop and from there - to thermal energy storage tank from where it can be returned to fuel-cell battery as direct delivery to diaphragm-electrode blocks in order to use them for preheating of fuel/oxidant or for direct input into diaphragm-electrode block. Thermal energy storage tank is intended for separation of electrical and thermal loads of fuel-cell battery in integrated thermoelectric plant. At low external electrical loads the fuel-cell battery and cooling loop can be used for high-efficiency production of hot water.
EFFECT: water cleanness in cooling loop.
