Series-breathing plate-silo-connected solid carbon fuel cell stack and power generation method thereof

Abstract

The utility model relates to a solid carbon fuel cell stack connected in series breathing type plate bins and a power generation method thereof, belonging to the technical field of fuel cells. The battery stack connects multiple sets of battery cells in series, and then the breathing device provides the positive and negative pressures of the anode intake, cathode intake of the first set of battery cells, and the positive and negative pressure of the anode output of the last set of battery cells to accelerate the electrolyte in the battery. Exchange speed, each group of battery cells includes an anode plate compartment and a cathode plate compartment, the electrolyte flow is carried out by connecting the anode plate compartment and the cathode plate compartment, and the anode plate compartment and the cathode plate compartment are insulated, and the anode plate compartment and the cathode plate compartment are set. The cathode plate compartments are insulated and connected through the electrolyte compartment or an insulating plate with a communication port, which reduces or omits the large-volume electrolyte compartment, reduces costs, and has a higher safety factor. The anode plate compartment or / and cathode plate compartment The spiral pipe design is adopted to extend the fuel channel, and at the same time, the fuel concentration matches the electrode surface area, which improves the electrode efficiency and fuel efficiency, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a breathing type solid carbon fuel cell stack, and also relates to a power generation method thereof. Background technique [0002] Energy is the backbone of the human economy and the necessary driving force for social activities. At present, the primary power required for social activities is mainly obtained through heat engines, and then converted into electrical energy. However, since the heat engine is limited by the "Carnot cycle", it is difficult to improve the efficiency, resulting in energy waste and increased pollution emissions. Therefore, the development of efficient and clean electric energy acquisition methods has become an inevitable direction of energy development. [0003] The fuel cell can directly convert the chemical energy stored in the fuel into electrical energy without being limited by the "Carnot cycle". It has the advantages of high energ...
