Answer:- 952 cells are there in the stack.
Solution:- From given data, The stack of cells produces [tex]2.20*10^8[/tex] W.
Each cell contribution is 231 kW.
Since, 1 kW = 1000 W
Let's convert kW to W and divide the total W of the stack by the W of single cell to get the number of cells as:
[tex]2.20*10^8W(\frac{1cell}{231kW})(\frac{1kW}{1000W})[/tex]
= 952 cells
So, from the calculations it is clear that 952 cells are required in a stack to produce [tex]2.20*10^8[/tex] W.
