The system is based on ethanol steam reformation to hydrogen that is used in polymer electrolyte fuel cells to produce electricity. We introduce the system design and overall system specifications, and report the experimental process of defining specifications for the produced hydrogen quality, a key variable affecting the final system cost, efficiency and durability. Results from development of individual subsystems are also presented together with discussion on the complete system integration.enhybrid power systemstelecommunication network reliabilitydistributed power generationfuel cellsethanolenergy conversionhydrogenfuel processing industrieschemical engineeringbatteriesresearch and development660conference paper
