Description
Technical Field
The invention relates to the technical field of fuel cell detection, in particular to a fuel cell single-chip testing device capable of realizing high and low temperature control.
Background
The proton exchange membrane is a key material in a Proton Exchange Membrane Fuel Cell (PEMFC), and the chemical structure of the proton exchange membrane is a fluorocarbon main chain and a side chain with a sulfonic group. Since the proton conductivity depends on water molecules, the proton conductivity is obviously reduced after the temperature is higher than 80 ℃. Meanwhile, low temperature PEMFCs also involve complicated water/heat management problems and problems such as susceptibility to catalyst poisoning.
Specifically, the PEMFC has an energy conversion efficiency of about 50%, which means that 50% of energy is released as heat energy, and if the heat dissipation effect is not good, the maximum temperature exceeds the design point temperature of the membrane (the maximum tolerance temperature of the conventional Nafion membrane is 80 ℃), and the temperature is not uniform, and the temperature distribution affects the gas supply, the electrochemical reaction, the transport characteristics of the proton exchange membrane, and the water management, which affects the overall efficiency and stability of the PEMFC. In addition, poor low-temperature cold start performance of the PEMFC is one of the main obstacles restricting practical popularization and application of the PEMFC, water, which is a reaction product during the operation of the PEMFC, is easily frozen at an ultra-low temperature, and the ice covers the surface of a cathode-side catalytic layer or blocks pores of a gas diffusion layer, thus preventing reaction gas from entering a porous electrode, reducing or even stopping the electrochemical reaction rate of the electrode, and further affecting the low-temperature start performance of the PEMFC. Meanwhile, repeated phase change of water freezing or ice melting can cause severe volume change of the porous electrode, damage is caused to the structure of a battery material, and the working performance and the service life of the battery are influenced to a certain extent.
In summary, the high and low temperature tests of the proton exchange membrane of the fuel cell are the central importance of the optimization research on the part.
