Abstract

The invention relates to a non-sealing solid oxide fuel battery pack with double gas channels, belonging to the field of electrochemical power generation. The non-sealing solid oxide fuel battery pack solves the problems that single batteries in a conventional single gas-chamber solid oxide fuel battery pack have nonuniform gas atmosphere, which affects the output voltage and output power of the battery pack. The battery pack is formed by connecting a plurality of single batteries in series or in parallel through connecting sheets, wherein a fuel-enriched vent pipe and an oxygen-enriched vent pipe are arranged relatively in parallel, the battery pack is arranged between the fuel-enriched vent pipe and the oxygen-enrich vent pipe, a plurality of fuel ports are arranged on the lateral wall of the fuel-enriched vent pipe with equal intervals, a plurality of oxygen ports are arranged on the lateral wall of the oxygen-enriched vent pipe with equal intervals, each fuel port corresponds to an anode of the single battery, each oxygen port corresponds to a cathode of the single battery, the anode and the cathode of the battery pack are respectively led out through an anode lead wire and a cathode lead wire, fuel-enrich gas is filled in the fuel-enriched vent pipe, and oxygen-enrich gas is filled in the oxygen-enriched vent pipe. The invention is mainly applicable to power generation.

Description

technical field [0001] The invention relates to a non-sealed solid oxide fuel cell group with double gas channels, which belongs to the field of electrochemical power generation. Background technique [0002] Solid oxide fuel cell (SOFC) has the advantages of high efficiency, low pollution and wide range of fuel sources. It is a clean and efficient energy system and is considered to be one of the main directions of new energy applications in the future. It is mainly composed of electrolyte, cathode and anode. The traditional double-chamber SOFC has two gas chambers, the fuel gas in the anode gas chamber and oxygen or air in the cathode gas chamber, and the two gas chambers are separated by electrolyte. In order to avoid the leakage of fuel gas and the mixing with oxygen, the electrolyte is required to be relatively dense and airtight, and the boundary must also be sealed with a sealing material. Due to the limited voltage and current output of single cells, in order to obt...
