Title:
THERMAL MANAGEMENT METHOD FOR FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2023/216150
Kind Code:
A1
Abstract:
Disclosed is a thermal management method for a fuel cell. The method comprises: providing an outlet fuzzy controller and an inlet fuzzy controller for a thermal management system for a fuel cell, wherein the thermal management system for a fuel cell comprises a water tank, a cooling water pump, a heat sink, and a stack, the outlet fuzzy controller uses an error between a current stack outlet temperature and a set target outlet temperature and an error change rate as input quantities, and uses a cooling water flow rate as an output quantity, and the inlet fuzzy controller uses an error between a current stack inlet temperature and a set target inlet temperature and an error change rate as input quantities, and uses the rotating speed of a fan of the heat sink as an output quantity; determining membership functions, fuzzy domains, and fuzzy rules of the outlet fuzzy controller and the inlet fuzzy controller; and parameterizing the membership functions, and optimizing the membership functions by means of particle swarm optimization and a genetic algorithm. According to the present invention, the temperature in the thermal management system for a fuel cell can be accurately controlled.
