Question

An experimental series stack of PEM cells produces 2.20 x 108 W of power. If each cell contributes 231 kW, how many cells are in the stack? (Round the answer to the nearest whole number.) cells

Answer 1

The Answer is 952 cells!

I hope this helps! ^^

Answer 2

Answer:- 952 cells are there in the stack.

Solution:- From given data, The stack of cells produces
`2.20*10^8` 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:

`2.20*10^8W((1cell)/(231kW))((1kW)/(1000W))`

= 952 cells

So, from the calculations it is clear that 952 cells are required in a stack to produce
`2.20*10^8` W.
