Abstract:
1. A solid oxide fuel cell, comprising: a plurality of tubular electrodes, being concentrically arranged to form a plurality of reaction chambers therebetween while enabling the polarity of a surface of any one of the plural electrodes to be the same as that of the corresponding surface of a neighbor electrode faced thereto, each tubular electrode being comprised of an anode layer, a cathode layer, and a solid electrolyte layer sandwiched between the anode layer and the cathode layer; a reacting gases supplying means, capable of supplying a fuel and a gas respectively to the anode and cathode of each tubular electrode, wherein the reacting gases supplying means further comprises: a preheat piping, connected to the reacting gases supplying means, for collecting the heat generated from the combustion reaction of residual fuel and gas to preheat the fuel and gas inside the reacting gases supplying means.
