Study on the improvement of performance of proton exchange membrane Fuel Cell by Magnetic effect

Abstract Oxygen and water are the main components of proton reaction, and the gradient magnetic field can affect their physical and chemical properties. The performance of PEMFC with gradient magnetic field on anode side was studied. On this basis, the performance of the battery under different battery temperature and hydrogen flow rate was tested. The experimental results show that the electric efficiency of PEMFC can be improved, the degradation of battery performance can be inhibited, and the service life of PEMFC can be extended under the same environmental variables. The experimental results can provide some reference value for improving PEMFC performance.
