Abstract: In this paper,the self propagating process for preparation of the vanadium based hydrogen storage battery alloy was controlled intelligently,and the comparison between the conventional PID control and the intelligent PID control was carried out.The results show that compared with the sample by conventional PID control,corrosion potential of the alloy by intelligent PID control positively shifts by 105 mV,and the decay rate of discharge capacity after 30 cycles is reduced by 17%.PID intelligent control can effectively improve the electrochemical corrosion resistance and electrochemical stability of the vanadium based hydrogen storage battery alloy.
