Problems solved by technology

The traditional way is to connect the cathodes of multiple batteries by winding silver or platinum wires; another way is to set a fixed cathode collector tank and fix the battery in the cathode collector tank. The method has extremely high requirements on the production process of the battery and the consistency of the battery, and in high-temperature operation, the deformation of the battery and the cathode collector tank is different, resulting in a contact gap and greater ohmic impedance. In addition, the fixed cathode collector tank The stress between the battery and the battery will cause structural damage to the battery

Abstract

The invention relates to a current collecting connection structure of a tubular solid oxide fuel cell. The current collecting connection structure comprises a base, a top cover, a current collecting column, a fixing column and a current collecting net; the end of the tubular SOFC electrolyte is inserted into the accommodating hole of the base middle; fix the current collecting column and the fixed column on the base, fix one end of the current collecting net on the fixed column, then intersperse and wind multiple tubular SOFCs and connect them with the cathode of the tubular SOFC, and connect the current collecting net with conductive glue and the cathode of the tubular SOFC, the other end of the collector net is fixed on the collector column, and the collector net and the collector column are connected with conductive glue; the anode end of the tubular SOFC is inserted into the receiving hole of the top cover, and the collector column is at the same time Insert the upper end into the positioning hole of the top cover. The connection structure can efficiently connect the current collectors of the external cathodes, and is applied to the parallel connection of two or more tubular solid oxide fuel cells, and the formed power generation units can be further connected in series and parallel to form the required output.

Description

technical field [0001] The invention relates to a current collecting connection structure of a tubular solid oxide fuel cell, belonging to the technical field of fuel cells. Background technique [0002] As a device that can directly convert chemical energy into electrical energy, fuel cells are not limited by the efficiency of the Carnot cycle compared to traditional internal combustion engines, and have the characteristics of high efficiency, cleanliness, safety and reliability. At present, fuel cells generally adopt a sandwich structure, that is, a pair of electrodes (anode and cathode) are separated by an electrolyte in the middle, and the electrolyte can only allow a single ion to pass through according to requirements. Compared with other types of fuel cells, solid oxide fuel cells (SOFC) not only have the common characteristics of fuel cells such as high efficiency and environmental friendliness, but also have a wide range of fuel applications. The base compound is t...
