Parallel breathing type single-plate silo solid carbon fuel cell stack and power generation method thereof

Abstract

The invention provides a parallel breath-type single-plate cabin solid carbon fuel cell stack and a power generation method thereof, belonging to the technical field of fuel cells. According to the cell stack, a plurality of groups of cell units are connected in parallel; each group of the cell units comprises an electrolyte cabin and a single plate cabin; each single plate cabin is arranged in the corresponding electrolyte cabin; electrolyte is injected into each electrolyte cabin; each single plate cabin is a positive electrode plate cabin and each electrolyte cabin is a negative electrode plate cabin; or each single plate cabin is a negative electrode plate cabin and each electrolyte cabin is a positive electrode plate cabin; positive and negative pressure of positive electrode input gas, negative electrode input gas and positive electrode output gas is provided by a breath device, and the exchanging of electrolyte in the cell is accelerated; the breath device is sufficiently utilized, and a manner of setting the single plate cabin, namely each positive electrode plate cabin or each negative electrode plate cabin is adopted, so that the use cost of the plate cabin is reduced, and furthermore, the electrolyte exchanging is accelerated; the positive electrode plate cabins or the negative electrode plate cabins adopt a spiral pipeline design and a fuel channel is lengthened; meanwhile, the fuel concentration is matched with the surface area of an electrode so that the electrode efficiency and the fuel efficiency are improved; the structure is simple, the manufacturing is easy and the cost is relatively low.

Description

technical field

[0001] The invention belongs to the technical field of fuel cells, and in particular relates to a direct solid carbon fuel cell stack, and also relates to its power generation method. 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 energy conversion e...
