The invention discloses a vehicle fuel cell waste heat management system and method, relates to the technical field of automobiles, and aims to form a vehicle low-cost combined heat and power supply system through special parts such as a heat exchange plate, a three-way valve and an electronic water valve on the basis of meeting the original functions. Waste heat generated by work of the fuel cellsystem is utilized to coordinate and control temperature rise, cooling, water heating in the vehicle and the like of the fuel cell system. Meanwhile, the problems of rapid temperature drop of the cooling medium of the fuel cell system, poor power generation performance, increased refrigeration load in summer and the like caused by large temperature difference of cooling mediums at two sides of the heat exchange plate are solved through the waste heat management system and each control strategy. Through a judgment strategy of signals of a first temperature sensor and a second temperature sensor, a first water pump, a electronic fan of a fuel cell radiator, an electric heater and the like are intelligently adjusted in real time, temperature lag or advanced control can be avoided, and meanwhile electric energy consumption of whole vehicle heat management can be reduced.
