The present invention relates to a strontium magnesium molybdenum oxide material having perovskite structure and the method for preparing the same. Citric acid is adopted as the chelating agent. By using sol-gel pyrolysis and replacing a portion of strontium in SrMgMoOby cerium and a portion of magnesium by copper, a material with a chemical formula of SrCeMgCuMoOis produced, where 0&#x2264;x&#x3c;2, 0&#x3c;y&#x3c;1, and 0&#x3c;&#x3b4;&#x3c;6. Thereby, the electrical conductivity of the material is improved. The perovskite-type cerium- and copper-replaced strontium magnesium molybdenum oxide significantly increases the electrical conductivity of the material and can be applied as the anode material for solid oxide fuel cell (SOFC).

The present invention relates to a solid oxide fuel cell stack modular structure, in that, being an integration of a plurality of fuel cell modules, it can determine the amount of fuel cell modules to be stacked in the modular structure according to an actual power output demand while ensuring airtightness in the modular structure, and moreover, with the modularization design, each fuel cell module in the modular structure that is malfunctioning can be detached and removed easily from the stack individually so as to be replaced by another operative fuel cell module.

Three bonding materials are provided on a first plate. The first bonding material is located between the second and third bonding materials. The first bonding material is thicker than the other bonding materials. A second plate is provided on the first bonding material. All of the plates and the bonding materials are heated to the softening point of the first bonding material. A load is exerted on the first bonding material to reduce the thickness of the first bonding material to that of the second and third bonding materials and transfer the load to the second and third bonding materials from the first bonding material. The temperature is raised to and kept at the crystallization point of the first bonding material. The temperature is raised to the wetting point of the second and third bonding materials.

Method for bonding two plates

Glass-ceramic sealant is disclosed for planar solid oxide fuel cells. The glass-ceramic sealant includes 0 to 40 mol % of silicon oxide, 0 to 15 mol % boron oxide, 0 to 10 mol % of aluminum oxide, 0 to 40 mol % of barium oxide, 0 to 15 mol % of calcium oxide, 0 to 15 mol % of lanthanum oxide and 0 to 5 mol % of zirconium dioxide. At 0&#xb0; C. to 600&#xb0; C., the thermal expansion coefficient of the sealant is 8 to 10 ppm/&#xb0; C.

An apparatus is disclosed for testing the performance of a sealant for solid oxide fuel cell packs. The apparatus includes an oven including a base, a platform provided on the base and a frame connected to the platform. An elevator is used to raise and lower the oven. A pressuring and testing chamber is provided on the platform. The pressuring and testing chamber includes a first body and a second body connected to the first body. A carrier is provided between the first and second bodies. The carrier includes a first plate and a second plate so that the sealant can be provided between the first and second plates. A pusher includes an end connected to the frame and another end for pushing the second plate. A pusher-driving unit is connected to the frame for raising and lowering the pusher.
