Description
Technical Field
The invention relates to the technical field of hydrogen energy automobiles, in particular to a method and a system for controlling the temperature of a hydrogen energy automobile electric pile.
Background
With the gradual depletion of fossil energy, research on new energy is gaining wide attention in order to find alternative energy. The hydrogen fuel cell, as a branch of new energy, can directly convert chemical energy of hydrogen and oxygen into electric energy through electrochemical reaction, and is also more and more widely applied to various places because of high power generation efficiency, which is regarded as one of the most potential clean energy sources in the world.
Proton Exchange Membrane Fuel Cells (PEMFCs), a type of fuel cell that can operate at low temperatures, are often used in vehicle engine systems and backup power systems. The operating principle of the proton exchange membrane fuel cell system is that air and hydrogen are input into a fuel cell stack to carry out electrochemical reaction, and then the stack converts chemical energy into electric energy and directly outputs the electric energy. The pem fuel cell system mainly includes three fluid subsystems, i.e., an air system, a hydrogen system and a cooling system, because a large amount of heat loss is accompanied when the stack generates electric energy, and a large amount of heat energy generated by the stack needs to be transferred by cooling water in order to prevent the stack from being damaged due to an excessively high temperature of the stack. On one hand, the fuel cell catalyst has higher electrocatalytic activity at high temperature, the temperature of the galvanic pile is too low, the activity of the catalyst is not high, the electrochemical reaction is insufficient, and the output performance of the galvanic pile can be influenced; on the other hand, hydrogen protons are transmitted between the anode and the cathode by using water as a bridge, and the temperature of the galvanic pile is too high, the humidity of the membrane electrode is low, so that the proton conduction is influenced, and the output performance of the galvanic pile is also influenced. Therefore, the stack needs to be at a proper temperature to output the highest electrical performance.
At present, a fuel cell system heats a cooling liquid by means of heat loss, and in the process of reaching rated power from starting, because the system temperature cannot respond quickly and a membrane electrode of a galvanic pile cannot perform electrochemical reaction efficiently, the output power of the galvanic pile cannot reach the rated power quickly, and therefore, in order to improve the power-up rate of the galvanic pile, the temperature of the galvanic pile needs to be improved quickly. Generally, a cooling loop of a fuel cell system is a water pump- > a radiator/heater- > a thermostat- > an electric pile- > a water pump, and at a low temperature, the fuel cell system can only heat coolant of the whole cooling circulation system through the work of the electric pile and the work of the heater, but because a pipeline of the cooling circulation is too long and the coolant is too much, the temperature of the electric pile is slowly increased, and the power increase requirement of the system cannot be quickly responded.
