摘要
A bioethanol reforming system, capable of converting a diluted water-ethanol mixture into hydrogen, is sized and set up to produce 5 kW of electric power via a polymer electrolyte membrane fuel cells (PEMFC). A part of the produced hydrogen supplies heat for the reforming reaction without impairing the power generation, then no additional fuel is required. According to the different configurations of the control variables, the heat released from the system is distributed between two different temperature ranges and coupled to a standard house-scale combined heat and power (CHP) cogeneration apparatus. Hot water can be produced continuously at a high enough temperature to cover the need of a F-class home in the moderately cold Northern Italy winter climate. With a micro accumulation solution and a careful choice of the set-points, also the sanitary hot water demand (DHW) of a 4-members family might be fulfilled with 2-3 daily cycles of the same system.
