- There are 144 fuel cells are joined in a series through interconnects.there will be 4 stacks having 36 cell in each stack.these stacks are then oragnised in series and parallel combination to form a single module to deliver required voltage and output power.this SOFCs module then combined with CHP system to get thermal . From this data answer the following questions. a)Calculate voltage losses of module?.this question is very compulsory. b)Electrical efficiency of module? C)Thermal efficiency when module combine with CHP system? D)Combined electrical and thermal efficiency? The input parameters of single cell are given below: Ocv=1.020 Current density=2250mA/cm2 Power density=850mw/cm2 Cell active area= 121cm2 Net power=15kw System fuel utilization=80% Operating temp=550°c Cell voltage=0.8v Power of single cell=103 watt.arrow_forwardi) Calculate V1 and V2 for the voltage across the string insulator having phase voltage of 33kV for transmission line using details tabulated in the Table 3(a).
