Abstract: The importance and performance requirements of proton exchange membrane fuel cell，and the core idea and basic principle of TRIZ (Theory of the solution for inventive problems) theory are introduced. Combined with actual technical solution，the real course of development about intellectual property improvement in proton exchange membrane fuel cell membrane materials is verified by parameters selection，contradiction matrix analysis and invention principles solving. On the basis of the solution process and corresponding conclusion，in virtue of abstractive invention principles introduced by TRIZ，reasonable prediction of development direction for membrane materials’ conductivity/stability is made. Improvement of film material can be achieved more targeted. For proton exchange film，improvement of fuel cell properties can be searched in at least such way as purification process，selection process and element coordination function of fuel cell.
