Abstract

The invention relates to a building combined cooling heating and power system and method based on a proton exchange membrane fuel cell. The system comprises a fuel cell module, a heat recovery module, a heat storage module and an electric energy management module. The heat recovery module is used for heating cooling water of the fuel cell module and supplying heat of the cooling water to the heat storage module through a heat exchanger; the heat storage module is connected with the heat exchanger through a buffer water tank to form a loop so as to recover heat of the cooling water and provide a heat source and a water source for heating equipment and a user hot water load respectively through a heat storage water tank; the electric energy management module includes a user electrical load and refrigeration equipment that may be powered by the fuel cell module. By heating the cooling water, the problem that the cathode side is frozen during cold start of the fuel cell is solved, the service life of the cell is prolonged, and the operation stability of the system is improved. Waste heat generated by operation of the fuel cell is reasonably utilized, an efficient combined cooling heating and power system is formed, and the comprehensive energy utilization rate of the system is increased.

Description

technical field [0001] The present application relates to the technical field of fuel cell cogeneration, in particular to a building cogeneration system and method based on proton exchange membrane fuel cells. Background technique [0002] Compared with traditional fossil fuels, hydrogen has the advantages of high efficiency, cleanliness and sustainability. The current main method of utilizing hydrogen is to convert and utilize the chemical energy released by the reaction of hydrogen and oxygen to form water. The chemical energy released by the reaction of hydrogen and oxygen to generate water can be converted into electrical energy through the fuel cell. The fuel cell is used as the power supply method for power generation equipment. Its efficiency is not limited by the Carnot cycle efficiency. There are no rotating moving parts during operation, and the noise is low. It also has the advantages of fast response to load changes, good power supply stability, clean and pollut...
