In this paper, hydrogen based sustainable electricity generator alternative utilizing Proton Exchange Membrane Fuel Cell (PMFC) is presented. Hydrogen and oxygen, with suitable operating condition are flowed to anode and cathode of fuel cell respectively to produce electricity, heat and water. Hence, the energy conversion process from chemical to electricity is clean, without combustion process that produces harmful carbon dioxide gas, and with higher efficiency as well. Based on fuel cell capacity and specification, process analysis is performed to get overall process parameters that are very critical and substantially affect the performance of the power generation. Instrumentation and control of this system are also designed and implemented to enable the direction of the system operation to achieve its better performance as well as to enable the evaluation of the system performance through continuous monitoring of overall system parameters. Some experimental results will also be shown in this paper to give illustration of the performance of the zero carbon emission and green energy conversion system.
