Embodiment Construction

[0032] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Such as Figure 1 to Figure 7 As shown, a flat solid oxide fuel cell stack device of the present invention is sequentially installed with a base 8, a base seal 7, a bottom plate 6 and a top plate 1 from bottom to top, and several groups of The battery stacks are stacked up and down. Each battery stack is stacked with a seal 2, a single cell frame 3, a seal 2 and a connector 5 from top to bottom. The single cell frame 3 is provided with a single The battery 4, the four corners of the base 8, the base seal 7, the bottom plate 6, the connecting body 5, the cell frame 3 and the seal 2 are provided with two holes, and because the base 8, the base seal 7 , bottom plate 6, connecting body 5, single cell frame 3 and sealing member 2 are stacked up and down, and the eight holes in each layer are correspondingly connected up and down to form eig...

Abstract

The invention discloses a flat plate type solid oxide fuel battery stack device. The flat plate type solid oxide fuel battery stack device comprises bases, single batteries, a single battery frame, a sealing piece, a connector, fuel pipelines and air pipelines, wherein the connector is provided with a battery coverage area and a heat exchange area, and the gas in the fuel pipelines and the air pipelines passes through a main air-intake pipeline, an air-intake collecting pipeline, an air-intake flow allocation pipeline, an exhaust collecting pipeline, an exhaust flow allocation pipeline and a main exhaust pipeline in sequence. The flat plate type solid oxide fuel battery stack device is in favor of the heat exchange between cold fluid and hot fluid and capable of reducing the temperature at a hot fluid outlet end, and the sealing piece is far away from the high temperature area, thereby improving the air tightness of fuel battery stacks and prolonging the service life of the sealing piece.

Description

technical field [0001] The invention relates to a solid oxide fuel cell, in particular to a flat-plate solid oxide fuel cell stack device. Background technique [0002] The process of thermal power generation is not only complicated (first convert the chemical energy of the fuel into thermal energy, then convert the thermal energy into mechanical energy, and finally convert the mechanical energy into electrical energy), but also produce a large amount of dust, carbon dioxide, SO 2 , NO x Such harmful substances seriously pollute the environment on which human beings live. Different from the principle of thermal power generation, fuel cells directly convert the chemical energy of fuel into electrical energy, so the efficiency of fuel cells is much higher than that of thermal power generation. As the fourth generation of new power generation technology after hydropower, thermal power and nuclear power, fuel cells have attracted the attention of countries all over the world. ...
