The invention belongs to the technical field of fuel cell measurement, and relates to a temperature and humidity detection device inside a fuel cell. By adopting an integrated temperature and humidity sensor embedded in the plate body, the simultaneous detection of temperature and humidity at any position inside the fuel cell is realized, and the influence of the installed sensor on the fuel cell structure is reduced. Multiple branch circuit boards are electrically connected to the control circuit board through pin headers. Each branch circuit board is equipped with at least two temperature and humidity sensors. Disassemble and replace the temperature and humidity sensor. The local electrochemical reaction inside the battery is monitored, and the adverse reaction of the fuel cell can be avoided by adjusting the external input parameters, thereby achieving the effect of optimizing performance and improving life. The use of wireless transmission reduces cumbersome wiring, facilitates the detection of bipolar plate assembly, and avoids wrong connections and open circuits.
Description
technical field [0001] The invention belongs to the technical field of fuel cell measurement, and more specifically relates to a temperature and humidity detection device inside a fuel cell. Background technique [0002] A fuel cell is a power generation device that directly converts the chemical energy in fuel into electrical energy through an electrochemical reaction. It has been more than 100 years since the fuel cell was invented. As energy and the environment have become key issues for the survival of human society, over the past 20 years, fuel cells, a highly efficient and clean energy conversion device, have received widespread attention from governments, developers and research institutions in various countries. Civil and military fields such as power supplies, distributed power stations, aerospace and underwater vehicles show broad application prospects. At present, fuel cell vehicles, power stations, and portable power sources are all in the demonstration stage. ...
