Abstract

The present invention provides a fuel cell combined heat and power system and an operating method. The fuel cell combined heat and power system includes: a fuel cell and a heat recovery water tank, wherein a hydrogen pipeline and an air pipeline are arranged inside the fuel cell, and the hydrogen pipeline The input end of the heat recovery water tank is connected with the external hydrogen tank, and the input end of the air pipeline is communicated with the outside air; the input end of the heat recovery water tank is connected with the external cold water pipe, and a gas dispersion device is arranged inside the heat recovery water tank, and the gas dispersion device is submerged in the heat recovery water tank. Below the cold water level, the input end of the gas dispersing device is connected to the output end of the air pipeline of the fuel cell, which is used to obtain the remaining gas on the air side after the chemical reaction of the internal electrodes of the fuel cell, and mix the remaining gas with the cold water in the heat recovery water tank. Contact heat exchange is performed to recover the exhaust heat of the stack exhaust inside the fuel cell. By implementing the present invention, the disadvantage of the low efficiency of the heat recovery system is compensated.

Description

technical field [0001] The invention relates to the field of energy and power, in particular to a fuel cell combined heat and power supply system and an operating method. Background technique [0002] In recent years, hydrogen energy has occupied an increasingly important position in the energy and chemical industry. The application of hydrogen energy has expanded from traditional chemical raw material gas and protective gas to many fields such as transportation power, energy power and grid energy storage. Especially in terms of comprehensive energy supply, the use of fuel cells to build distributed energy supply stations to provide thermal and electrical supply can greatly improve energy consumption and greenhouse gas emissions. It is of great significance for optimizing energy distribution, promoting energy conservation and emission reduction, and protecting the ecological environment. [0003] Proton exchange membrane fuel cell (PEMFC) system is a fuel cell-based system d...
