Description
technical field [0001] The invention relates to the field of fuel cells, in particular to a proton exchange membrane fuel cell temperature monitoring system and a method thereof. Background technique [0002] A fuel cell is a device that generates electricity by the interaction of fuel and oxidant, and can obtain high power generation efficiency. In the fuel cell system, with the polymer electrolyte membrane as the center, an anode and a cathode are arranged on both sides. Hydrogen as a fuel undergoes an electrochemical reduction reaction at the anode, and oxygen as an oxidant undergoes an electrochemical oxidation reaction at the cathode. At this time, through The resulting movement of electrons produces electricity. [0003] The working temperature parameter of the membrane electrode of the proton exchange membrane fuel cell unit has guiding significance for analyzing the power generation performance of the battery. Monitoring the working temperature parameter of the memb...
