Fuel cell humidifier modeling method, equipment and medium

Abstract

The embodiment of the invention discloses a fuel cell humidifier modeling method, equipment and medium. Wherein, the method includes: building a fuel cell humidifier simulation model under the Modelica simulation environment, the simulation model including a wet gas channel, a dry gas channel, and protons between the wet gas channel and the dry gas channel exchange membrane; the simulation model is divided into a plurality of regions along the dry gas flow direction; the first side gas properties of each channel in each region are used as equation parameters to construct the water transport equations of each region; according to the The water transmission volume equation group, and the inlet gas attribute setting value and outlet gas attribute setting value of each channel of the humidifier under the set working condition, and the calibration coefficient to be calibrated in the water transfer equation group is calibrated . This embodiment takes both calculation efficiency and simulation accuracy into consideration, and accurately reflects the humidification effect of each area inside the humidifier.

Description

technical field [0001] Embodiments of the present invention relate to fuel cell simulation technology, in particular to a fuel cell humidifier modeling method, equipment and medium. Background technique [0002] The core component of the proton exchange membrane fuel cell is the membrane electrode. The proton exchange membrane is located in the middle of the membrane electrode and plays the role of conducting protons and isolating reactants and electrons. It needs a certain amount of water to play a good role in proton conduction. Therefore, when the fuel cell is working, a humidifier is generally used at the inlet to humidify the gas entering the cell, so as to avoid the direct dry gas from causing the water content of the proton exchange membrane to decrease, which will affect the performance of the cell. [0003] In the prior art, a humidifier simulation model is generally established based on the user's target humidity modeling method, and the gas humidity attribute conf...

Problems solved by technology

This method can only calculate the overall humidification effect of the humidifier, but cannot show the gas humidification process inside the humidifier, and it is difficult to form an effective guidance for the selection of humidifiers
