The invention discloses a
cathode-supported
direct carbon fuel cell, which comprises a fuel bin, an
anode side collector layer, an
anode layer, an
electrolyte layer, a
cathode active layer, a
cathode-supporting layer, a cathode side collector layer, a carbon fuel layer, a porous
ceramic layer, a carbon fuel input tube, a carrier gas intake tube, a carrier gas output tube and an
oxygen or air intake tube, a
cell is arranged in the fuel bin, the
anode side collector layer, the anode layer, the
electrolyte layer, the cathode
active layer, the cathode-supporting layer and the cathode side collector layer are arranged sequentially from the outside to the inside, and moreover, the anode side collector layer, the carbon fuel layer and the porous
ceramic layer are superposed in the fuel bin sequentially from the top down. Since the
cell is a cathode-supported
cell which directly utilizes
solid carbon as fuel and the outside of the cell is provided with the fuel input tube, the cell has the advantages of simple structure,
high energy efficiency, environment-friendliness, no leakage,
corrosion and explosion dangers and the like, can realize the
continuous feeding of fuel and the diversity of the fuel
electrode, and is convenient and easy to operate.
