| Summary: | 碩士 === 元智大學 === 機械工程學系 === 92 === The research of this thesis is aimed to conduct assessment of the feasibility research on fuel cells used in power supply system of military communication Equipment. The findings have been listed as follows:
(1)The maximum power consumption of a communication base station is
4120 w, power consumption ranging between 3000w~4500w.The maximum power consumption of a relay station is 1059 w, power consumption ranging between 1000w~1100w.Fuel cells hence used as a main power supply system or auxiliary power supply system of a communication station require 5kw; and 2Kw fuel cells would be sufficiently used for a delay station.
(2)Actual investment cost of lead acid battery per Kw would be 10002.52 NT dollars / hour; fuel cell per Kw would be: 204003.15 $ NT dollars. Considering the cost, lead acid battery is suitably used for short period of time (within 21 hours) as power backup. For More than 21 hours of power backup, fuel cells may be most economical.
(3)Based on six years of a life cycle of a fuel cell, instead of the lead acid battery, full cells for the back-up power of fixed communication equipment are assessed in comparison for economic benefits. The total investment cost with fuel cells will save 1277250000$ NTD for a period of six years.
(4)Main power and back power backup of the military communication equipment are supplied by fuel cells, and a total exhaust volume of 773799.48 Kgs- CO2 can be reduced.
