Solid-oxide fuel cell (SOFC) power generation system and burner thereof

The invention discloses a burner which comprises a premixing cavity and a burning cavity which are communicated; the premixing cavity is connected with an air input pipe and a gas input pipe; the burning cavity consists of a housing body, an insulating jacket is lined in the housing body and internally provided with a porous medium; and an ignition area is formed between the upper surface of the porous medium and the insulating jacket. The burner can fully ensure the flame stability in burning of gas through the porous medium evenly arranged between the premixing cavity and the ignition area, and lead the temperature distribution of the burning area in gas burning to have good evenness; and the invention further provides a solid-oxide fuel cell (SOFC) power generation system applying the burner.
