Abstract:- One of the challenges in the path of a hydrogen economy is hydrogen compression and storage issues. Compressed gas storage using a conventional mechanical compressor suffers from product gas contamination and energy efficiency. Recent developments in proton exchange membrane (PEM) fuel cells have offered possibilities for efficient compression of hydrogen in PEM cells. This alternative method offers operational and efficiency benefits over the conventional compressor. PEM electrolysis based hydrogen production utilizing renewable energies has been identified as a clean source of energy. Subsequent compression of product hydrogen using the PEM cell compressor can help overcome its storage problem and bring the hydrogen economy into reality soon. This efficient hydrogen compression technique can improve the overall efficiency of a renewable hydrogen production system. This paper summarizes the modeling of a feasible PEM electrochemical compression process and its verification using actual experimental data. Modeling will be done using the Mathematica software. Modeling results are expected to provide a better understanding of the electrode kinetics of PEM cell compression at high pressure differentials. Modeling and future experimentation can help in commercialization of the PEM compressor to boost the hydrogen economy. Analysis will be done to calculate the energy requirement and the efficiency of the system at different output pressures. The PEM cell compressor can be served as an intermediate step to mechanical compression to reduce the number of compression stages and energy usage. Results from the theoretical calculations will be used to compare energy use and efficiency for the combination of PEM cell and mechanical compression with mechanical compression alone, over a pressure range.
