An electric power generation system using fuel cells, wherein the system includes a stack of fuel cells each having an anode, electrolyte and a cathode. Associated with the anodes are anode passageways divided into two groups. Each group is formed by anode passageways connected to one of the two anode gas exhaust manifolds. Associated with the cathodes are cathode passageways divided into two groups. Each group is formed by cathode passageways connected to one of the two cathode gas exhaust manifolds. The anode exhaust gas in each of the manifolds is maintained completely separate from that in the other manifold. Similarly, the cathode exhaust gas is separate in the two manifolds. Fuel gas from a supply is fed to an inlet manifold supplying all of the anode passageways in which the reforming reaction takes place. Anode exhaust gas from the outer manifold is supplied to the inlet manifold to mix with the fuel gas to the anode passageways. Oxidizing gas such as air is fed to an inlet manifold supplying all of the cathode passageways. Cathode exhaust gas from the outlet manifold is supplied to the oxidizing gas supply path.
