Abstract

The invention provides a parallel breath-type double-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, a positive electrode plate cabin and a negative electrode plate cabin; each positive electrode plate cabin and each negative electrode plate cabin are arranged in the corresponding electrolyte 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; a manner of arranging each positive electrode plate cabin and each negative electrode plate cabin is adopted; each positive electrode plate cabin and each negative electrode plate cabin 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; and the structure is simple, the manufacturing is easy and the cost is relatively low. A positive electrode exhausting pipe of the cell stack is connected with the breath device; water steam exhausted by the positive electrode exhausting pipe returns back to a positive electrode gas inlet pipe and a negative electrode gas inlet pipe through the breath device, so that the utilization rate of water is improved; and extra pre-heating or heating is not needed so that energy sources are saved.

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...
