NTT is developing a phosphoric acid fuel cell energy system for telecommunication co-generation systems to reduce energy costs and help preserve the environment. Fuel cells are used to provide electrical power to telecommunication equipment and the heat energy that is generated is used by the absorption refrigerator to cool the telecommunication rooms throughout the year. We fieldtested this fuel cell energy system in a telephone office for three years. Heat recovered water from fuel cell stack coolant was supplied to the absorption refrigerator and further extra-heat was recovered by a heat exchanger. The total heat recovery amount was about 86000 kcal/h (the heat recovery efficiency was 20%) under 200kW operation. The absorption refrigerator was supplied about 49000kcal/h of heat and operated with 0.7 of coefficient of performance throughout the year. The electrical efficiency was mainteined more than 38% after 13000h operation.
