摘要： An arrangement is proposed for a system with at least two molten carbonate or solid oxide fuel cell stacks (1, 2, 3). The cathode flows (14) of these stacks are connected in series while the anode flows (25) are in parallel. All stacks have an internal reforming device for a hydrocarbon fuel. Anode gas is recycled (24) from the stack outlets to the inlets. The invention allows the stacks to be of the same design and this reduces manufacturing costs. The cathode streams between the stacks are cooled by, for example, adding streams of cool air (15) to them. The cathode inlet temperatures can, therefore, be controlled by relatively inexpensive low temperature air valves. The invention allows the system to be designed with few heat exchangers, if any. The per pass utilisation of all the oxidant streams and fuel streams are low. The efficiency of the system is typically 4-5 percentage points higher than that of equivalent conventional systems.

摘要： In an electric power generation system (2), there is a cross-flow stack (4) of fuel cells (6) each having an anode, electrolyte, and a cathode. Associated with the anodes are anode passages which in each cell are divided into a first group formed by anode passages (28a) and a second group formed by anode passages (28b). Fuel gas, for example methane from a supply (26) is fed via path (34) to an inlet manifold (38a) to the anode passages (28a), and a portion of anode exhaust gas from the anode passages (28a) is fed via an exhaust outlet manifold (40a) and lines (42, 46) to an inlet manifold (38b) feeding the anode passages (28b). A reforming reaction takes place in the anode passages (28a and 28b). The other part of the anode exhaust gas from the exhaust manifold (40a) is fed via lines (42 and 44) to the line (34) to mix with the fuel gas. Atmospheric air provides the oxidising gas supplied on line (18) to the cathodes. That oxidising gas is heated in a heating arrangement (21) in which anode exhaust gas from the anode passages (28b), and supplied on line (50), is burnt.

摘要： 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).
