FIELD: electrical engineering.
SUBSTANCE: fuel element comprises electrolyte 23, anode 22 arranged on one side of electrolyte 23 and has fuel consumption surface, cathode 24 arranged on opposite side of electrolyte and fuel gas channel 225n that has first channel 14h to distribute fuel gas in preset zones on oxidising gas feed surface, second channel 22 to feed distributed fuel gas in zones, and section 21n to feed fuel gas from first channel 14h into second channel 22. Fuel element consumes major part of fed fuel gas in zones of fuel gas consumption surface. Fuel gas channel 225n has section 14hg, 52n to suppress fuel gas leaks between first channel 14h and second channel 22.
EFFECT: continuous operation of fuel gas.
