<p>In an electric power generation system (2), there is a stack (4) of fuel cells (6) each having an anode (10), electrolyte (8), and a cathode (12). Associated with the anodes (10) are anode passages divided into two groups, a first group formed by anode passages (14a) connected to an anode gas exhaust manifold (48a) and a second group formed by anode passages (14b) connected to an anode gas exhaust manifold (48b). Associated with the cathodes (12) are cathode passages divided into two groups, a first group formed by cathode passages (16b) connected to a cathode gas exhaust manifold (44b) and a second group formed by cathode passages (16a) connected to a cathode gas exhaust manifold (44a). The anode exhaust gas in manifold (48a) is wholly separate from that in manifold (48b) as is the cathode exhaust gas in manifold (44a) from that in manifold (44b). Fuel gas, for example methane from a supply (26) is fed via path (28) to an inlet manifold (30) supplying all the anode passages (14a and 14b) in which a reforming reaction takes place. Anode exhaust gas from the outlet manifold (48b) is supplied to the inlet manifold (30) to mix with the fuel gas to the anode passages. Oxidising gas such as air is fed via path (38) to an inlet manifold (40) supplying all the cathode passages (16a and 16b). Cathode exhaust gas from the outlet manifold (44a) is supplied by path (46a) to the oxidising gas supply path (38).</p> |
