^4fCOMPARISON BETWEEN BATTERIES AND FUEL CELLS AND ENVIRONMENTAL EVALUATION OF THE PV-FUEL CELL HYBRID POWER PLANT

摘要

^7fBoth batteries and fuel cells have their own unique contributions to electric power systems. Those two power sources also contain a great potential to back up severe PV power fluctuations under inclement weather conditions. In this paper comparison between batteries and fuel cells is carried out in detail only for their PV power backup options, so their common attributes and different attributes will be discussed. Then, environmental evaluation of the proposed hybrid plant was made in terms of plant's land requirement and lifetime CO{sub}2 emissions, and then compared with that of the conventional fossil-fuel power generating forms.
