“…They concluded that the combined system as a whole was technically feasible, however economic considerations might hinder implementation practically. Oshima et al [44] carried out a study on recovering FC exhaust to power a cooling system meant for telecommunication equipment. Their main focus was to look into different methods of heat recovery from the fuel cell and draw appropriate conclusions on which heat recovery system was better.…”

“…In recovering heat from PAFC's exhaust gases, the temperature at which water condenses played a crucial part because the heat recovery from the exhaust gases depended on the water recovery temperature. A brief discussion of this was presented above in Oshima et al's work [44]. For year round operation of the VARS, the cooling water temperature at the absorber and condenser was set to 15 o C. This value was derived considering the effect that cooling water has on both COP and the concentration of solution.…”

“…This method of thermal coupling might pose some challenges: first it might lead to corrosion at the cold end of the desorber and second the desorber might be too large in terms of volume, warranting more heat transfer area because the exhaust gas has a low thermal capacity. Other research groups have used a thermal coupling fluid, mainly water [44,47,54,55] which is heated either by the fuel cell exhaust gas or by the fuel cell coolant loop.…”
