Problems solved by technology

The proposal specifies that fasteners are to be placed between the individual stacks, but does not further specify how the fasteners are to be placed
Moreover, the use of the device of this patent application in practice shows that in order to securely connect the battery stacks, the fasteners need to be well matched and arranged, resulting in relatively high size requirements for installation, and it is difficult to implement positioning and installation. Defects of unstable installation, resulting in unstable conduction and failure of the seal between the battery stacks, etc., all of which can further improve the design

Abstract

The invention discloses a solid oxide fuel cell stack array and a power generation system thereof. The solid oxide fuel cell stack array comprises a support body and a cell stack group, wherein the support body is of a hierarchical structure, and at least comprises an upper tray and a lower tray; the cell stack group is carried by the lower tray; the upper tray is placed on the cell stack group; the cell stack group comprises a plurality of cell stacks; the cell stacks are horizontal; fastening pieces are arranged among the cell stacks. The solid oxide fuel cell stack array is characterized in that support columns are arranged between the upper tray and the lower tray to construct the support body; the fastening pieces on the left and right sides of the cell stacks are set as movable blocks and fixed blocks; the support columns are provided with screw holes; force application screw rods are combined with the support columns through the screw holes, and the inner ends of the force application screw rods are pressed against the outer surface of respective movable block; the strokes of the force application screw rods are adjusted through rotation of the force application screw rods, so that the side faces of the movable blocks generate pressures on adjacent cell stacks, and the cell stack group is pressed and fastened. The structure is convenient to implement, and is stable and effective.

Description

technical field [0001] The invention relates to an array structure of battery stacks in a solid oxide fuel cell (Solid oxide fuel cell, SOFC) power generation system and the power generation system thereof. Background technique [0002] The solid oxide fuel cell (Solid Oxide Fuel Cell, SOFC) power generation system can directly convert the chemical energy in the fuel into electrical energy. The fuel includes natural gas, liquefied gas, synthetic gas, biogas, hydrogen, etc. The power generation process is efficient and clean. A promising way to generate electricity. The SOFC power generation system can be modularized and integrated to build large-scale distributed power stations. The existing natural gas pipeline network can provide the natural gas required for power generation, and the generated electricity can be supplied to nearby buildings, communities, factories, etc. It can also transmit power to the national grid. Therefore, the SOFC power generation system is a power...
