Abstract

The invention provides a fuel cell heat recovery system. The self-heating heat management system includes a fuel cell water circuit one, a passenger compartment water circulation circuit one, and a battery pack water cycle circuit one; the battery pack water cycle circuit one includes a battery cooler one and a battery pack water cycle Loop 1 is connected in parallel with water circulation loop 1 of the passenger compartment through battery cooler 1; the water circulation loop of the passenger compartment is connected in series with the fuel cell water loop; the external heating configuration thermal management system includes the second battery pack water circulation loop, the battery pack The water circulation loop 2 includes the battery cooler 2, the battery pack water circulation loop 2 is connected in parallel with the water circulation loop 2 of the passenger compartment through the battery cooler 2, and the water circulation loop 2 of the passenger compartment is connected in parallel with the water loop 2 of the fuel cell through the fuel cell 2. The invention can maximize the heat utilization of the cooling circuit by changing the circulation flow path, thereby reducing energy consumption and improving the overall energy utilization efficiency of the automobile.

Description

technical field [0001] The invention belongs to the field of fuel cell vehicle energy management, in particular to a fuel cell heat recovery system. Background technique [0002] The cold start of fuel cells under low temperature conditions, especially below zero, is an important factor restricting the wide application of fuel cells. At present, fuel cell stacks with advanced technology in the world optimize the membrane electrode assembly of fuel cell cathodes and use 3D fine mesh Grid cathode plate, so as to improve cathode drainage and water storage capacity, and its supply gas does not require external humidification, thereby reducing the intake of external moisture, and combined with reasonable shutdown and parking purge strategies to strictly control the fuel cell The water content is low, so that the fuel cell can still warm up with high power at ultra-low temperature and quickly reach the ideal working temperature. The realization of these functions puts forward extr...
