Rural cogeneration system based on fuel cell system and operation method of rural cogeneration system

Abstract

The invention discloses a rural cogeneration system based on a fuel cell system and an operation method of the rural cogeneration system. The system utilizes a wind-solar complementary hydrogen production device to provide necessary hydrogen for a fuel cell, a fuel cell cogeneration module is utilized to provide electric energy and heat energy for residents, and hot water discharged by the fuel cell supplies energy to cold water in heated brick bed water circulation through a heat exchanger, so that self-humidification and cooling of the fuel cell are realized, a heated brick bed is designed into efficient energy storage equipment, and meanwhile, the overall efficiency and the heat utilization rate of the system are improved. A biomass energy comprehensive utilization module can be used for combustion of a household stove and can also be used for a gasifier for subsequent power generation, high-temperature flue gas obtained by power generation is used for heating the heated brick bed and providing hot water, the high-temperature flue gas generated in the using process of the household stove enters a flue in the heated brick bed to heat the heated brick bed, various renewable energy sources in the north are comprehensively utilized, and the overall utilization efficiency of rural energy sources is improved while rural pollution emission is reduced.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of energy, in particular to a rural cogeneration system based on a fuel cell system and an operating method thereof. Background technique [0002] With the increasingly serious problems of global warming and air pollution, seeking a clean energy has become the consensus of all countries in the world. Hydrogen energy, as a new energy source, has high calorific value, clean combustion and no pollution. . [0003] In rural areas where the land is vast and the population is sparsely populated, wind energy, light energy, and biomass energy resources are abundant, but these various renewable resources have not been well utilized. Residents often burn biomass energy directly for heating. The cost of power generation and transmission is relatively high and it is suitable for distributed energy applications. Wind power and photovoltaics are highly complementary, and the use of two renewa...
