The invention discloses a PEMFC bipolar plate flow channel cross section optimization method and a three-dimensional proton exchange membrane fuel cell. The optimization method comprises the followingsteps of 1, establishing a three-dimensional proton exchange membrane fuel cell geometric model; 2, meshing the three-dimensional proton exchange membrane fuel cell geometric model; 3, performing analog computation on the three-dimensional proton exchange membrane fuel cell geometric model; 4, extracting key simulation parameters, namely for each three-dimensional proton exchange membrane fuel cell geometric model, at the same position, extracting the key simulation parameters capable of laterally reflecting the influence of each three-dimensional proton exchange membrane fuel cell geometricmodel on the performance of the fuel cell, wherein the key simulation parameters comprise the speed of the cathode reaction gas, the concentration of the cathode reaction gas and the current density of the battery; and 5, opti
