Embodiment Construction
[0043] The invention discloses an anti-condensation air intake pipeline of a fuel cell stack test bench and a control method thereof. The test system and method proposed by the invention can realize precise control of the air intake state of the stack air circuit and avoid the actual physical damage of hot and humid air. The state produces uncontrollable changes, and at the same time avoids the resulting condensation phenomenon, and avoids the liquid water in the air intake pipeline from negatively affecting the test equipment and the test piece.
[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art w...

The invention discloses an anti-condensation air inlet pipeline of a fuel cell stack test board and a control method. A second heater, a temperature sensor and a dew point sensor are additionally arranged behind a humidifier and a first heater and in front of an electric pile test piece, the temperature sensor detects the temperature of air entering the electric pile test piece in real time, and the dew point sensor is used for detecting the humidity of air entering the galvanic pile test piece in real time; a controller obtains a measurement result through the temperature sensor and the dew point sensor. The working state of the second heater is set to control the state of air entering the electric pile test piece; thus, the air inlet state of air is accurately controlled, it is guaranteed that wet and hot air does not change the state (such as dew formation) before entering a cavity of the electric pile, then the accuracy of a test result is guaranteed, and the situation that normalworking states of downstream equipment and a tested piece are affected by air dew formation is avoided.
Description
technical field [0001] The invention relates to the technical field of fuel cells, in particular to an anti-condensation intake pipeline and a control method for a fuel cell stack test bench. Background technique [0002] Proton exchange membrane fuel cell, also known as fuel cell, has the advantages of high energy conversion rate, no noise, and fast response, and is considered to be a new energy power generation system that will be developed in the future. A fuel cell uses hydrogen and air as the anode and cathode reaction gases to generate electricity through an electrochemical reaction. In fuel cell development projects, the stack is often used as the object to be tested, and hydrogen and air are supplied to the stack through certain equipment and control strategies. During this process, the state of the air needs to be precisely controlled, including the temperature, humidity, pressure, and flow of the gas. [0003] However, in the traditional stack test equipment, aft...
