Abstract: Thermotechnical units of solid oxide fuel cell (SOFC) are integrated as a whole one. The units may include a burner, a reformer and a heat exchanger. The integrated units can be easily assembled into an SOFC system with cell stacks. Thus, the present invention has a simple structure, operates with ease, saves operational cost, runs with fewer utilities, decreases heat dissipation and enhances system performance.

Abstract: A burner reformer is provided for a power generating system using fuel cell. A burner is contained inside the reformer. The reformer absorbs heat from the burner and other heat source to reduce heat loss and save connecting wires. The present invention avoids flashing back of hydrogen. When fuel is lean, flame would not easily die and the system can thus work stably.

Abstract: A fuel cell system includes a fuel cell unit, a reformer with a catalyst and heat pipes around the catalyst, and a combustor connected to the heat pipes. A first fuel pipe sends fuel into the reformer. The fuel is reformed in the reformer. A first air port sends air into the reformer. An anode pipe sends the reformed fuel into the fuel cell unit. The chemical reaction of the reformed fuel occurs in the fuel cell unit. A cathode pipe sends the air into the fuel cell unit. A residual reformed fuel pipe sends residual reformed fuel into the combustor. A hot air pipe sends hot air into the combustor. The residual reformed fuel pipe is mixed with the hot air and burned in the combustor. A second fuel pipe sends more fuel into the combustor if necessary. A second air port sends air into the combustor if necessary.

Abstract: A solid oxide fuel cell system includes a fuel cell unit for generating electricity via executing an electrochemical reaction on fuel, a fuel supply for storing the natural gas, water and air and a re-composing unit for re-composing natural gas, water and air into the fuel. A pipe transfers the natural gas, water and air into the re-composing unit from the fuel supply. Another pipe transfers the fuel into the fuel cell unit from the re-composing unit. Another pipe transfers hot air into the re-composing unit from the fuel cell unit. A mixing unit mixes air with residual fuel from the fuel cell unit. A combusting unit burns the mixture from the mixing unit. A heat-exchanging unit executes heat-exchanging between air and the exhaust from the combusting unit. The heat-exchanging unit includes an air-inletting port, an exhaust port and another port for sending hot air into the fuel cell unit.

Abstract: An apparatus is disclosed for measuring the permeability of an anode of a solid oxide fuel cell. The apparatus includes a specimen container, an air reservoir and a recorder. The specimen container includes a can and a cover. The can includes a tunnel defined therein and a cavity in communication with the tunnel. The anode can be disposed in the cavity. The cover includes a tunnel defined therein and a bulger inserted in the cavity and pressed against the anode so that air can penetrate the anode and travel into the tunnel of the can from the tunnel of the cover. The air reservoir is in communication with the cover. The recorder measures and records the pressure and temperature of air in the air reservoir before and after the air is introduced into the specimen container from the air reservoir.
