Patent ID: 7157169

Claim:
A fuel cell stack comprising: a stack formed by stacking cell plates, each of the cell plates provided with an electrolyte layer, a fuel electrode layer formed on one surface of the electrolyte layer and an air electrode layer formed on another surface of the electrolyte layer; and combustion heater plates disposed among the cell plates, the combustion heater plates heating the cell plates using gas for combustion including fuel and air and separated from gas for generation, and each of the combustion heater plates being provided with a porous combustion support that has a plate shape and a gas non-pass layer that covers the porous combustion support, exhibits electrical conductivity and serves as an inter connector, wherein the cell plates include first cell plates and second cell plates, each of the first cell plates provided with a first electrolyte layer, a first fuel electrode layer formed on one surface of the first electrolyte layer and a first air electrode layer formed on another surface of the first electrolyte layer and each of the second cell plates provided with a second electrolyte layer, a second fuel electrode layer formed on one surface of the second electrolyte layer and a second air electrode layer formed on another surface of the second electrolyte layer, wherein the first fuel electrode layer of the first cell plates and the second fuel electrode layer of the second cell plates are opposed to one another, and wherein each of the combustion heater plates is intermittently arranged with respect to both the first cell plates and the second cell plates.
