N2 - Although much work has been done to optimize individual components of electrolyzers and fuel cells, very little has been done to simulate and optimize the entire system. A thorough paper review has been conducted to increase the accuracy of the PEM electrolyzer model and simulation discussed in this study. Data on optimal thicknesses and electrical properties of various electrolyzer elements was collected from various sources and collated. The simulation was then implemented to optimize the current collector rib dimensions for maximum performance and efficiency over a variety of temperatures. This paper shows higher temperatures significantly improve the efficiency of the cell while also increasing the optimal rib width dimensions. The increased efficiency is most likely due to the excess heat contributing towards the threshold energy required for the electrolysis while the varying resistances of the proton exchange membrane, with respect to temperature, can explain the increased rib width.
