Abstract

The invention discloses an automotive fuel cell combined heat and power generation system. The system mainly comprises a natural gas tank (1), a natural gas compressor (2), an air compressor (3), an air preheater (4), a natural gas reformer (5), a solid oxide fuel cell stack (6), a combustor (9), a water evaporator (10) and a water tank (11). The invention further provides a working method on the basis of the automotive fuel cell combined heat and power generation system. According to the working method, the hydrogen ions in the natural gas are separated by the natural gas reformer (5) to form hydrogen, the hydrogen and high-temperature air passing through the air preheater (4) generate electrochemical reaction in the solid oxide fuel cell stack (6), and the hydrogen and oxygen, which do not generate electrochemical reaction, generate hot gas through the combustor (9). According to the automotive fuel cell combined heat and power generation system and the working method thereof, the natural gas not only can be used for providing power for the vehicles through natural gas engines, but also can generate electric energy and heat energy when the natural gas engines do not work, so as to satisfy certain special purposes.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell cogeneration system for natural gas engine vehicles and a working method thereof. Background technique [0002] Natural gas engines for power and heating produce CO when burned 2 , CO, and NO x etc., where NO x It is the main pollutant that forms acid rain. The greater the NO concentration, the stronger the toxicity. N0 2 It is more toxic, it is easy to mix with the hemoglobin in human and animal blood to capture oxygen, make the blood hypoxic, and cause central nervous palsy, N0 2 It also strongly stimulates the mucous membrane of the respirator tube, causes lung disease, and also damages the heart, liver, kidney and hematopoietic tissue in the body, and will cause death in severe cases. Power plants often propose many denitrification solutions for NOx, but these methods cannot be applied to natural gas machines for vehicles. [0003] Atmospheric CO 2 The sh...
