In this work the artificial intelligence technique was used to study the mischmetal composition of the La x Ce y Pr z Nd 1-x-y-z Ni 3.55 Co 0.75 Mn 0.4 Al 0.3 hydrogen storage alloys. Applied the uniform distribution method to design the composition of mischmetal. Based on the vast and uniform experiments the electrochemical properties such as maximum discharge capacity, voltage specialty and the cycle life were studied. The experiment data were analyzed by the pattern recognition method. The relationship model between the mischmetal composition and electrochemical properties of the alloys was finally proposed clearly.
