Abstract

The invention provides a simple and effective thermal management system of a water-cooling proton exchange membrane fuel cell and a control method of the thermal management system. The thermal management system mainly comprises an electric pile, a water tank provided with a heating device, a cooling water circulating pump, a radiator, a cooling water pile inlet temperature sensor, a cooling water pile outlet temperature sensor, a cooling water pile inlet pressure sensor and a controller of the thermal management system. The control method following pressure change is provided to overcome the defects of lag, great overshooting, system coupling and the like caused by temperature change tracking in the traditional control strategy. The radiator is mainly used for controlling the cooling water inlet temperature of the pile and mainly controls the rotating speed of a radiator fan according to the cooling water inlet temperature of the pile of the fuel cell; and the cooling water circulating pump is mainly used for controlling the cooling water flow in the whole thermal management system and mainly controls the rotating speed of the circulating pump according to the cooling water inlet pressure of the pile of the fuel cell.

Description

technical field [0001] The invention relates to a thermal management system structure and a control method of a water-cooled fuel cell stack, specifically a simple and effective thermal management system and a control method for controlling the temperature of a water-cooled proton exchange membrane fuel cell stack. Background technique [0002] A fuel cell is a power generation device that directly converts the chemical energy of fuel into electrical energy, among which proton exchange membrane fuel (PEMFC) cells are the most widely used. PEMFC has the characteristics of high efficiency, cleanliness, and environmental friendliness. It can be used in various fields such as electric vehicles, distributed power stations, aviation, military industry, and civil use, and has a very broad application prospect. [0003] PEMFC will generate heat energy equivalent to electric energy during the power generation process. If the heat energy generated cannot be removed in time and effecti...
