The invention relates to a tubular oxygen-deficit catalytic self-reforming electrode for a SOFC. The tubular oxygen-deficit catalytic self-reforming electrode is characterized by comprising a gas enclosed pipe, a porous honeycomb catalyst, an electrolyte isolation layer cathode layer and an anode supporting electrode tube, wherein the anode supporting electrode tube is divided into three working zones, i.e., from left to right, a self-reforming working zone, an electrode reaction working zone and a tail gas treatment working zone; the porous honeycomb catalyst is embedded in the gas enclosed pipe; the gas enclosed pipe is embedded into the self-reforming working zone of the anode supporting electrode tube, and the length of the gas enclosed pipe is equal to the length of the self-reforming working zone; and the electrolyte isolation layer cathode layer sleeves the electrode reaction working zone of the anode supporting electrode tube, and the length of the electrolyte isolation layer cathode layer is equal to the length of the electrode reaction working zone. The tubular oxygen-deficit catalytic self-reforming electrode provided by the invention integrates two critical functions, i.e., fuel reforming and electrode power-generation, into the electrode tube, so the manufacturing cost, weight and size of the tubular SOFC are maximally reduced.
